After you've learned the basics (or if you already have some GPS experience), you may want to try out some of the IntelliMap 640c's many advanced navigation features. That brings us to Section 4, Advanced GPS Operations. This section contains the rest of the unit's GPS command functions, organized in alphabetical order. When you come to a GPS menu command on the IntelliMap 640c's screen, you can look it up in the manual by skimming over the table of contents, just flipping through Section 3 or scanning through the command portion of Section 4. This unit is ready to use right out of the box, but you can fine tune and customize its operation with dozens of options. We describe how to use general system options along with GPS options in Section 5, System Setup and GPS Setup Options. Section 5 is organized in alphabetical order. In Section 6, we go into more detail on one of the IntelliMap 640c's most remarkable capabilities Searching. We'll introduce a search example in the Basic GPS Operation section, but there are so many map items you can search for, we had to give this function its own section in the manual! For example, did you know this unit can look up business phone numbers, functioning as a virtual Yellow Pages? Well show you how in Section 6. Finally, in Section 7, we offer Supplemental Material, including a list of the GPS datums used, warranties and customer service information. Now, if you're into the fine details, glance over the next segment on specifications to see just how much GPS power your IntelliMap 640c contains. It's important to us (and our power users), but, if you don't care how many watts of power the unit has, or how many waypoints it can store, skip ahead to important information on how our GPS works, on page 4.

Introduction to GPS and WAAS
Well, now you know the basics of how the unit does its work. You might be ready to jump ahead to Section 2, Installation & Accessories, on page 11, so you can mount your IntelliMap 640c and plug in the power. Or you might want to see how our text formatting makes the manual tutorials easy to skim. If that's the case, move on to "How to Use This Manual" on page 8. But, if you want to understand the current state of satellite navigation, look over this segment describing how GPS and its new companion WAAS work together to get you where you're going. The Global Positioning System (GPS) was launched July 17, 1995 by the United States Department of Defense. It was designed as a 24hour-a-day, 365-days-a-year, all weather global navigation system for the armed forces of the U.S. and its allies. Civilian use was also available at first, but it was less accurate because the military scrambled the signal somewhat, using a process called Selective Availability (SA). GPS proved so useful for civilian navigation that the federal government discontinued SA on May 2, 2000, after the military developed other methods to deny GPS service to enemy forces. Reliable accuracy for civilian users jumped from 100 meters (330 feet) under SA to the present level of 10 to 20 meters (about 30 to 60 feet.) Twenty-four satellites orbit 10,900 nautical miles above the Earth, passing overhead twice daily. A series of ground stations with precisely surveyed locations controls the satellites and monitors their exact locations in the sky. Each satellite broadcasts a low-power signal that identifies the satellite and its position above the earth. Three of these satellites are spares, unused until needed. The rest virtually guarantee that at least four satellites are in view nearly anywhere on Earth at all times.
A minimum of three satellites are required to determine a 2D fix.
The system requires signal reception from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation (your height above sea level also called altitude). This is called a 3D fix. Remember, the unit must have a clear view of the satellites in order to receive their signals. Unlike radio or television signals, GPS works at very high frequencies. These signals can be easily blocked by trees, buildings, an automobile roof, even your body. Like most GPS receivers, this unit doesnt have a compass or any other navigation aid built inside. It relies solely on the signals from the satellites to calculate a position. Speed, direction of travel, and distance are all calculated from position information. Therefore, in order for the IntelliMap 640c to determine direction of travel, you must be moving and the faster, the better. This is not to say that it wont work at walking or trolling speeds it will. There will be more "wandering" of the data shown on the display. GPS alone is plenty accurate for route navigation, but the U.S. Federal Aviation Administration has special aircraft navigation needs that go beyond basic GPS. Consequently, the FAA has developed a program to boost GPS performance with its Wide Area Augmentation System (WAAS). The FAA commissioned the system on July 11, 2003. WAAS is designed to increase GPS accuracy to within 7.6 meters vertically and horizontally, but according to the FAA, it consistently comes within 1-2 meters horizontally and 2-3 meters vertically. It does this by broadcasting correction signals on GPS frequencies. Your unit automatically receives both GPS and WAAS signals. There are, however, some fringe areas of the U.S., including parts of Alaska, that do not yet receive robust WAAS coverage. Continued WAAS development is planned to extend WAAS coverage in the years to come. WAAS boosts the accuracy of land GPS navigation, but the system is designed for aircraft. The satellites are in a fixed orbit around the Equator, so they appear very low in the sky to someone on the ground in North America. Aircraft and vessels on open water can get consistently good WAAS reception, but terrain, foliage or even large manmade structures can sometimes block the WAAS signal from ground receivers. You'll find that using your GPS receiver is both easy and amazingly accurate. Its easily the most accurate method of electronic navigation available to the general public today. Remember that this receiver is 7

only a tool. Always have another method of navigation available, such as a map or chart and a compass. Also remember that this unit will always show navigation information in the shortest line from your present position to a waypoint, regardless of terrain! It only calculates position, it cant know whats between you and your destination, for example. Its up to you to safely navigate around obstacles, no matter how youre using this product.
How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow "keystrokes" appear as boldface type. So, if you're in a real hurry (or just need a reminder), you can skim the instructions and pick out what menu command to use by finding the boldface command text. The following paragraphs explain how to interpret the text formatting for those commands and other instructions: Arrow Keys The arrow keys control the movement of dotted cross-hair lines on your mapping screen called the cursor. The arrow keys help you move around the menus so you can execute different commands. They are represented by symbols like these, which denote the down arrow key, the up arrow, the left arrow and the right arrow: . Keyboard The other keys perform a variety of functions. When the text refers to a key to press, the key is shown in bold, sans serif type. For example, the "Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU. Menu Commands a menu command or a menu option will appear in small capital letters, in a bold sans serif type like this: ROUTE PLANNING. These indicate that you are to select this command or option from a menu or take an action of some kind with the menu item. Text that you may need to enter or file names you need to select are show in italic type, such as trail name. Instructions = Menu Sequences Most functions you perform with this unit are described as a sequence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading. For example, instructions for navigating a trail would look like this: 1. From the Map Page, press MENU|MENU| to MY TRAILS|ENT. 2. Press to Trail 1|ENT|| to NAVIGATE|ENT. 3. You are asked to wait while it converts the trail into a route. 8
4. The wait message disappears and the IntelliMap 640c begins showing navigation information along the trail. Now, begin moving and follow your IntelliMap 640c. Translated into complete English, step 1 above would mean: "Start on the Map Page. Press the Menu key twice. Next, repeatedly press (or press and hold) the down arrow key to scroll down the menu and select (highlight) the My Trails menu command. Finally, press the Enter key." Step 2 would mean: "Press the down arrow key repeatedly to scroll to the trail named Trail 1, and press Enter. Next, press the right arrow key and then the down arrow key to highlight the Navigate command, then press Enter."

Section 2: Installation & Accessories

Preparations

You can install the GPS system in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drilling any holes in your vehicle or vessel! 1. Determine the approximate location for the GPS unit, so you can plan how and where to route the cables for the antenna and power. This will help you make sure you have enough cable length for the desired configuration. 2. Determine the approximate location for the GPS antenna module and its cable route. 4. Determine the location of your battery or other power connection, along with the power cable route. 6. Install the GPS antenna and route the antenna cable to the GPS unit. 7. Install the power cable and route it to the GPS unit. 8. Mount the GPS unit.
GPS Antenna/Receiver Module Installation
The IntelliMap 640c package includes the EGC-12w GPS module. This device contains the IntelliMap 640c's external antenna and receiver for GPS and WAAS signals. The antenna/receiver module comes with a 25foot extension cable. This module can be mounted on a flat surface, pole, or an optional magnet is available for temporary mounting on any ferrous surface.
EGC-12w Module, bottom view (left) and top view (right).
You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, route the cable to the unit, plug it in the center socket on the back and your system is ready to use. See the module's instruction sheet, publication part number 988-0148-371, for complete installation directions. In an automobile, you may achieve good results by placing the external antenna on the top of the dash or at the base of the windshield. A piece of the rubber non-skid shelf liner material available in recreational vehicle supply stores will help hold the antenna in place. This may not work well if you have a cab-over design pickup truck camper or motor home. If dashboard reception is poor, relocate the antenna module elsewhere on the vehicle for a clearer view of the sky.

Power Connections

The IntelliMap 640c works from a 12-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, but you might have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery. CAUTION: When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug. This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket. In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs. If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit. If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. If the cable is not long enough, splice #18 gauge wire onto it. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the in-line fuse holder to the red lead as close to the power source as possible. 12

Power/lights on and off

To turn on the unit, press PWR. As the unit powers up, the Map Page is displayed first. (To switch to another page, press PAGES| or to Page Name|EXIT.) To turn on the backlight, press PWR again. The unit has three backlight levels to select from. Repeatedly pressing PWR will cycle through the backlight settings and turn off the backlight. Turn off the unit by pressing and holding the PWR key for 3 seconds.

Main Menu

The unit has a Main Menu, which contains some function commands and some setup option commands. The tutorial lessons in this section will deal only with functions, the basic commands that make the unit do something. The GPS will work fine for these lessons right out of the box with the factory default settings. But, if you want to learn about the various options, see Sec. 5, System Setup and GPS Setup Options. You can access the Main Menu from any of the three Page screens by pressing MENU|MENU. To clear the menu screen and return to the page display, press EXIT. 24

Main Menu.

The Main Menu commands and their functions are: Screen command: changes the contrast or brightness of the display screen. Sounds command: enables or disables the sounds for key strokes and alarms and sets the alarm style. Transparency command: adjust the level of transparency for menus. Alarms command: turns GPS alarms on or off and changes alarm thresholds. Route Planning command: used to plan, view or navigate a route. My Trails command: shows, hides, creates and deletes plot trails. Also used to navigate or backtrack a trail. Cancel Navigation command: turns off the various navigation commands. Used to stop navigating after you have reached your destination waypoint, Point of Interest or map cursor location; or after you reach the end of a route or trail. GPS Setup command: sets various GPS receiver options. System Setup command: sets general configuration options. Sun/Moon Calculations command: finds the rising and setting time of the sun and the moon. Trip Calculator command: shows trip status and statistics. Timers command: controls the up timer, down timer and alarm clock settings. Browse MMC Files command: this allows you to view the installed MMC card and the files it contains.

The unit has three Page displays that represent the three major operating modes. They are the Satellite Status Page, the Navigation Page and Map Page. They are accessed by pressing the PAGES key, then using or to select a Page. Exit the Pages Menu by pressing EXIT.
Pages Menu showing Map display options.
Satellite Status Page The Satellite Status Page, shown in the following images, provides detailed information on the status of the unit's satellite lock-on and position acquisition. To get to the Satellite Status Page: Press the PAGES key, then use or to select STATUS. Leave the Pages Menu by pressing EXIT. No matter what Page you are on, a flashing current position indicator/question mark symbol and flashing GPS data displays indicate that satellite lock has been lost and there is no position confirmed. The Satellite Status Page shows you the quality and accuracy of the current satellite lock-on and position calculation. WARNING: Do not begin navigating with this unit until the numbers have stopped flashing! 26
Satellite Status Page. The first figure (left) indicates unit has not locked on to any satellites and does not have a fix on its position. The second figure (right) shows satellite lock-on with a 3D position acquired (latitude, longitude and altitude), and WAAS reception.
This screen shows a graphical view of the satellites that are in view. Each satellite is shown on the circular chart relative to your position. The point in the center of the chart is directly overhead. The small inner ring represents 45 above the horizon and the large ring represents the horizon. North is at the top of the screen. You can use this to see which satellites are obstructed by obstacles in your immediate area if the unit is facing north. The GPS receiver is tracking satellites that are in bold type. The receiver hasn't locked onto a satellite if the number is grayed out, therefore it isn't being used to solve the position. Beneath the circular graph are the bar graphs, one for each satellite in view. Since the unit has twelve channels, it can dedicate one channel per visible satellite. The taller the bar on the graph, the better the unit is receiving the signals from the satellite. NOTE: One of the data display options for the Satellite Status page is "Position Error" (horizontal position error), which can appear in one of the page's data boxes. Position Error will show you the expected error from a benchmark location. In other words, if the Position Error box shows 50 feet, then the position shown by the unit is estimated to be within 50 feet of the actual location. It also gives you an indicator of the fix quality the unit currently has. The smaller the position error number, the better (and more accurate) the fix is. If the position error flashes dashes, then the unit hasn't locked onto the satellites, and the number shown isn't valid. For details, see Customize Page Displays, on page 76. 27

Set a Waypoint

A waypoint is an electronic address based on the latitude and longitude of a position on the earth. A waypoint represents a location, spot, or destination that can be stored in memory, then be recalled and used later on for navigation purposes. 40
You can create a waypoint at the cursor position on the map, or at your current position while you are navigating. You can create a waypoint at any location by manually entering the position's latitude and longitude. You can copy waypoints from your unit to your personal computer with MapCreate software. When you want to repeat a trip, these archived waypoints can be reloaded into your GPS unit. To create and save a Waypoint: These first two techniques use the Quick Save method, the fastest and easiest way to create a waypoint.
Create Waypoint at Current Position While you are traveling, press WPT|WPT. The waypoint is saved and
automatically given a name with a sequential number, such as "waypoint 003." The waypoint symbol and number appear on the map. NOTE: The Quick Save method uses the default waypoint symbol until you edit an existing waypoint and change its symbol. (Edit Waypoint Symbol is described in Sec. 4.) After you have changed a waypoint symbol the unit will remember the one you chose and use it the next time you "quick save" a waypoint. To revert back to the default symbol, edit a waypoint and choose the original symbol, or use the Reset Options command (described in Sec. 5).

The velocity scale at the top left side of the graph changes dynamically based upon the maximum velocity of the current for that day. Slack water, the period of little or no current, is represented by the Slack Water Line (SWL). The flood appears above the SWL and the ebb appears below the SWL. You can look up tidal current data for other dates by changing the month, day and year selection boxes. 85
To select another date: 1. Use to highlight month, day or year, then press ENT. 2. Use to select the desired month, day or year and press ENT. To clear the information screen, press EXIT. Tide Information NauticPath charts contain Tidal Information, represented at large zoom ranges by a box icon with the letter "T." These icons will appear when you are zoomed in to a 6-mile range. The icon stands for a Tidal Station location. An example is displayed at right. When you zoom in to a sufficiently small zoom range (0.8 nautical mile), the icon becomes an animated gauge showing a rising or falling tidal height for the selected station at the present time. At larger zoom ranges, you can select the boxed "T" icon and it becomes an animated gauge with a pop-up name box. The name box disappears seconds.

The intersection in our example is shown below.
Map Page showing results of an intersection search. The cursor points to the located intersection.

The background map is suitable for many navigation chores, but for maximum accuracy and much more detail, you need our optional mapmaking software, MapCreate 6, or one of our special plug-and-play mapping cards. Some unit features such as searching for businesses and addresses won't work without a custom MapCreate map. There is so much detail in our background map (and even more in MapCreate) that we'll describe their contents and differences in Section 3, Basic GPS Operations, on page 30. Another portion of the IntelliMap 502C's onboard memory is devoted to recording GPS navigation information, which includes waypoints, event marker icons, trails and routes. This lets you look back the way you came. Think of this data storage like the hard drive memory in a computer or a tape in a cassette tape recorder. You can save several different GPS data files, erase 'em and record new ones, over and over again. Like any computer file, these GPS Data Files (file format *.usr) can be shared between Eagle GPS or sonar/GPS units or even personal computers. This IntelliMap 502C has one more thing in common with a personal computer. Just as computers have a floppy disk drive for storing and exchanging files, the unit has a slot for an MMC (MultiMedia Card) or SD card (Secure Digital card) flash memory card. These solid-state memory devices are about the size of a postage stamp, but can hold data ranging from 8 MB to 2 GB in size. (Compare that to a floppy disk's 1.44 MB capacity!) This unit uses all that MMC space for two key GPS purposes. First, you can backup your onboard GPS Data Files by copying them to the MMC. Since the MMC is removable like a floppy disk or a cassette tape, you can store these GPS Data Files on a personal computer equipped with an MMC card reader. Or store them on a pocketful of MMCs if you don't have a computer. Our MapCreate mapping software can save, edit or create its own GPS Data Files, which can be copied to the MMC and then loaded from the MMC into the unit's memory. No matter where they come from, GPS Data Files must be loaded from the MMC into memory before the IntelliMap 502C can use them. The other key GPS use for MMCs is storage of special high-detail, custom maps, which you can produce on your computer with our MapCreate software. These MapCreate custom maps contain much greater detail than the basic background map. These Custom Map Files (file format *.lcm) can also be shared between Eagle GPS or sonar/GPS units and personal computers. This unit automatically reads Custom Map Files directly from the MMC or SD card. To use a custom map, all you need to do is slide an MMC containing a map into the IntelliMap 502C. 5

4. The wait message disappears and the IntelliMap 502C begins showing navigation information along the trail. Now, begin moving and follow your IntelliMap 502C. Translated into complete English, step 1 above would mean: "Start on the Map Page. Press the Menu key twice. Next, repeatedly press (or press and hold) the down arrow key to scroll down the menu and select (highlight) the My Trails menu command. Finally, press the Enter key." Step 2 would mean: "Press the down arrow key repeatedly to scroll to the trail named Trail 1, and press Enter. Next, press the right arrow key and then the down arrow key to highlight the Navigate command, then press Enter."
Section 2: Installation & Accessories

Preparations

You can install the GPS system in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drilling any holes in your vehicle or vessel! 1. Determine the approximate location for the GPS unit, so you can plan how and where to route the power cable. This will help you make sure you have enough cable length for the desired configuration. 2. Determine the location of your battery or other power connection, along with the power cable route. 3. Install the power cable and route it to the GPS unit. 4. Mount the GPS unit. The IntelliMap 502C uses an internal antenna to achieve a GPS lock. In order to get a strong signal, you need to select a mounting location that has a clear, unobstructed view of the sky. NOTE: The IntelliMap 502C is designed for open-cockpit boats, but the unit will probably work in an automobile or a closed-cockpit boat if it's mounted with a clear view through the windshield or other windows. This probably will not work if you have a cab-over design pickup truck camper or motor home, or a boat cabin with limited visibility. Remember, for optimum operation, this unit should be mounted in the open with nothing obstructing its view of the sky.

Power Connections

The IntelliMap 502C works from a 12-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power bus, but you might have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery. CAUTION: When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug. 11

This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket. In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs. If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit. If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. If the cable is not long enough, splice #18 gauge wire onto it. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the in-line fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse.

WARNING: This product must be independently fused with the enclosed 3-amp fuse (or equivalent), even if you connect to a fused accessory or power buss. If a malfunction happens inside the unit, extensive damage can occur if the enclosed fuse is not used. As with all electrical devices, this unit could be damaged to a point that it is not repairable and could even cause harm to the user when not properly fused. 12
CAUTION: Failure to use the enclosed 3-amp fuse will void your warranty! For a replacement, use a type 3AG 3-amp fuse. This unit has reverse polarity protection. No damage will occur if the power wires are reversed. However, the unit will not work until the wires are attached correctly.

NMEA Cable Connections

NMEA is a standard communications format for marine electronic equipment. For example, an autopilot can connect to the NMEA interface on the IntelliMap 502C and receive positioning information. The IntelliMap 502C can exchange information with any device that transmits or receives NMEA 0183 data, however, a communications cable is not available for the unit at press time. If you need to create a NMEA 0183 connection, consult customer service. Service contact information is located in the back of this manual. See the diagram on the preceding page for general wiring connections. Read your other products owners manual for more wiring information. NMEA Wiring To exchange NMEA data, the IntelliMap 502C has one NMEA 0183 version 2.0 communication port. Com port one (Com-1) can be used to receive NMEA format GPS data. The com port can also transmit NMEA format GPS data to another device. A data cable should contain three wires. Com-1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for signal ground.

Now that you have your IntelliMap 502C installed, move on to Section 3, Basic GPS Operations. There, we'll present a series of step-by-step tutorials to teach you the basics of GPS navigation.
Section 3: Basic GPS Operations
This section addresses the unit's most basic GPS operations. The tutorials presented in Sec. 3 follow a chronological order. Sec. 4, Advanced GPS Operations, will discuss other more advanced functions and utilities. Material in Sec. 4 is arranged in alphabetical order. Before you turn on the unit and find where you are, it's a good idea to learn about the different keys, the three Page screens and how they all work together. BUT, if you just can't wait to get outside, turn to the one-page Quick Reference on page 34.

Keyboard

1. PWR/LIGHT (Power & Light) The PWR key turns the unit on and off and activates the backlight. 2. PAGES Pressing this and the arrow keys (4) switches the unit between the three different page screens. (Satellite Status Page, Navigation Page and Map Page.) Each page represents one of the unit's major operation modes.
3. MENU Press this key to show the menus and submenus, which allow you to select a command or adjust a feature. This also accesses search functions for streets, intersections, addresses and highway exits. 4. ARROW KEYS These keys are used to navigate through the menus, make menu selections and move the map cursor. 5. ENT/ICONS (Enter & Icons) This key allows you to save data, accept values or execute menu commands. It is also used to create event marker icons. 6. EXIT The Exit key lets you return to the previous screen, clear data or erase a menu. 7. WPT (Waypoint) The Waypoint key is used to save and recall waypoints, search for waypoints and access the waypoint list. It also launches the Point-of-Interest (POI) search menus and is involved in some navigation functions. 8. ZOUT (Zoom Out) This key lets you zoom the screen out. This lets you see a larger geographic area on the map. Less detail is seen as you zoom out. 9. ZIN (Zoom In) This key lets you zoom the screen in. Zooming in lets you see greater detail in a smaller geographic area on the map.

Pages Menu, showing some Map display options.
Satellite Status Page The Satellite Status Page, shown in the following images, provides detailed information on the status of the unit's satellite lock-on and position acquisition. To get to the Satellite Status Page: Press the PAGES key, then use or to select STATUS. (Clear the Pages Menu by pressing EXIT.) No matter what Page you are on, a flashing current position indicator/question mark symbol and flashing GPS data displays indicate that satellite lock has been lost and there is no position confirmed. The Satellite Status Page shows you the quality and accuracy of the current satellite lock-on and position calculation. WARNING: Do not begin navigating with this unit until the numbers have stopped flashing!
Satellite Status Page. Left view indicates unit has not locked on to any satellites and has no fix on its position. Center view shows satellites being scanned. Right view shows satellite lock-on with 3D position acquired (latitude, longitude and altitude), and WAAS reception.
This screen shows a graphical view of the satellites that are in view. Each satellite is shown on the circular chart relative to your position. The point in the center of the chart is directly overhead. The small inner ring represents 45 above the horizon and the large ring represents the horizon. North is at the top of the screen. You can use this to see which satellites are obstructed by obstacles in your immediate area if the unit is facing north. The GPS receiver is tracking satellites that are in bold type. The receiver hasn't locked onto a satellite if the number is grayed out, therefore it isn't being used to solve the position. Beneath the circular graph are the bar graphs, one for each satellite in view. Since the unit has twelve channels, it can dedicate one channel per visible satellite. The taller the bar on the graph, the better the unit is receiving the signals from the satellite. NOTE: One of the data display options for the Satellite Status page is "Position Error" (horizontal position error), which can appear in one of the page's data boxes. Position Error will show you the expected error from a benchmark location. In other words, if the Position Error box shows 50 feet, then the position shown by the unit is estimated to be within 50 feet of the actual location. This also gives you an indicator of the fix quality the unit currently has. The smaller the position error number, the better (and more accurate) the fix is. If the position error flashes dashes, then the unit hasn't locked onto the satellites, and the number shown isn't valid. (For details, see Customize Page Displays, on page 74.) 25

Zoom Range

Position, distance and bearing data
When the map is zoomed out far enough, most POIs appear as square dots. As you zoom in closer, the symbols become readable icons. In the 0.2 mile zoom example at right, the cursor has selected the Cupps Caf POI, which triggers a pop-up box with the POI name. This pop-up box works on POIs at any zoom range.
In some urban areas, businesses are so close to one another that their POI icons crowd each other on the screen. You can reduce screen clutter and make streets and other map features easier to see by simply turning off the display of POIs you're not watching for. (To see how, check the text on Map Detail Category Selection, page 79. It shows how to use the Map Categories Drawn menu to turn individual POI displays off and on.) Even though their display is turned off, you can still search for POIs and their icons will popup when your unit finds them for you. The Map Page has its own menu, which is used for several functions and for setting various options. To access the Map Page Menu, from the Map Page, press MENU. The Pages Menu also offers several map display options under the Map Page category. To access them, press PAGES| or to MAP| to Option|EXIT.
Digital Data map page option.
In pages that have two major windows (such as two maps) you can toggle back and forth between the two windows by pressing PAGES|PAGES. This allows you to change which map your cursor moves on, and which map the menu operates on.

Resize Window command Resize Window is another extremely handy feature for pages that have two major windows. You can change the relative size of the windows, as well as horizontal or vertical layout, to suit your viewing preference. Here's how: 1. From any two-window display, press MENU| to RESIZE WINDOW|ENT. 2. Four flashing arrows appear along the centerline dividing the two windows. Press an arrow key perpendicular to the centerline to adjust 32

Find Your Current Position
Finding your current position is as simple as turning the unit on. Under clear sky conditions, the unit automatically searches for satellites and calculates its position in approximately one minute or less. NOTE: "Clear sky" means open sky, unobstructed by terrain, dense foliage or structures. Clouds do not restrict GPS signal reception. If for some reason satellite acquisition takes longer, you may be inside a structure or vehicle or in terrain that is blocking signal reception. To correct this, be sure you are positioned so that the unit's antenna module has as clear a view of the sky as possible, then turn the unit off and back on again.
Moving Around the Map: Zoom & Cursor Arrow Keys
The map is presented from a bird's eye view perspective. The current zoom range shows in the lower left corner of the screen. 1. Press the ZIN key (zoom in) to move in closer and see greater detail in a smaller geographic area. 2. Press the ZOUT key (zoom out) to move farther away and see less map detail, but a larger geographic area. When you are traveling, the map will automatically move as you move. This keeps your current location roughly centered on the screen. You can manually pan or scroll the map northward, southward, eastward or westward by using the arrow keys, which launch the cross-hair map cursor. This allows you to look at map places other than your current position. To clear the cursor, press EXIT, which jumps the map back to the current position or the last known position.
Use the cursor to determine the distance from your current position (or last known position, when working indoors) to any map object or location. Simply use the arrow keys to position the cursor over the object or place. The distance, measured in a straight line, appears in the popup data box. Press EXIT to clear the cursor.
Distance measured by cursor
Pop-up name box Selected wreck
Cursor line Cursor line The selected wreck (the Empress) to the southeast is 12.81 miles away.
Selecting Any Map Item with the Cursor
1. Use the zoom keys and the arrow keys to move around the map and find the item you wish to select. 2. Use the arrow keys and center the cursor cross-hair on the desired object. On most items, a pop-up box will give the name of the selected item.
This unit has an extremely handy Cursor Undo feature that lets you instantly return to the previous location you were looking at without scrolling. It works like this: Use the cursor (arrow keys) to scroll the map to some far away location or waypoint. Press EXIT to clear the cursor and jump back to your current position on the map. When you want to take another peek at that distant place, just press EXIT again. You can use this trick to toggle between your current position and your destination without a lot of scrolling.

Set a Waypoint

A waypoint is simply an electronic "address," based on the latitude and longitude of a position on the earth. A waypoint represents a location, spot, or destination that can be stored in memory, then be recalled and used later on for navigation purposes. You can create a waypoint at the cursor position on the map, or at your current position while you are navigating. You can create a waypoint at any location by manually entering the position's latitude and longitude. You can copy waypoints from your unit to your personal computer with MapCreate software. When you want to repeat a trip, these archived waypoints can be reloaded into your GPS unit. To create and save a Waypoint: These first two techniques use the Quick Save method, the fastest and easiest way to create a waypoint.
Create Waypoint at Current Position While you are traveling, press WPT|WPT. The waypoint is saved and
automatically given a name with a sequential number, such as "waypoint 003." The waypoint symbol and number appear on the map. NOTE: The Quick Save method uses the default waypoint symbol until you edit an existing waypoint and change its symbol. (Edit Waypoint Symbol is described in Sec. 4.) After you have changed a waypoint symbol, the unit will remember the one you chose and use it the next time you "quick save" a waypoint. To revert back to the default symbol, edit a waypoint, choose the original symbol or use the Reset Options command see Sec. 5.

Step 4: vehicle continues on its way; number waypoint symbol is visible on map. Create Waypoint on Map
1. Use the arrow keys to move the cursor to the place where you want to make a waypoint. 2. Press WPT|WPT. The waypoint is saved and automatically given a name with a sequential number, such as "waypoint 001." The waypoint symbol and number appear on the map.
Create Waypoint by Entering a Position 1. Press WPT| to MY WAYPOINTS| to NEW|ENT.
2. Press to ENTERED POSITION|ENT| to CREATE|ENT.
3. Press to LATITUDE|ENT. Enter the latitude by pressing or to change the first character, then press to the next character and repeat until the latitude is correct. Press ENT. 4. Press to LONGITUDE|ENT. Enter the longitude by pressing or to change the first character, then press to the next character and repeat until the longitude is correct. Press ENT, then EXIT|EXIT to return to the previous page display. The waypoint is saved and automatically given a name with a sequential number, such as "waypoint 001." The waypoint symbol and number appear on the map and in the waypoint list.

The man overboard position is also stored in the waypoint list for future reference. It can be edited the same as any other waypoint. This prevents the inadvertent loss of the current Man Overboard position. To cancel navigation to MOB, press MENU|MENU| to CANCEL NAVIGATION|ENT| to YES|ENT. The unit stops showing navigation information.
Navigate to Cursor Position on Map
The GO TO CURSOR command: navigates to the current cursor position on the map. It's a quick and handy way to navigate to anything you can see on the map display. 1. Use the cursor (controlled by the arrow keys) with the zoom in and zoom out keys to maneuver around the map until you find a location you want to go to. 2. Center the cursor over the location to select it. See the example in the following figure. (Many map items such as waypoints, Points of Interest, towns, etc. can be "selected," and appear "highlighted" with a pop-up box. Other features, such as a river or a street intersection will not appear "highlighted," but the cursor will take you to those locations just the same.)
Navigate to cursor. In this example, the cursor has selected the town of Oologah, Oklahoma.
3. Press MENU|ENT and the unit will begin navigating to the cursor location. The Map Page will display a red line from your current position to the cursor position. The Navigation Page displays a compass rose showing navigation information to your destination. See the following examples.
The 30-mile zoom figure at left clearly shows the red course line connecting your current position to your destination. The 30-mile zoom, center, shows both current position and direction to destination on screen. The Navigation Page, right, will also show navigation information.
To stop navigating to the cursor, use the Cancel Navigation command: press MENU|MENU| to CANCEL NAVIGATION|ENT| to YES|ENT. The unit stops showing navigation information.
Navigate to a Point of Interest
For POIs that are in view on the map, you can easily use the Navigate to Cursor command above; just use the cursor to select the POI. The other method involves searching for POIs with the Find Waypoint command, launched with the WPT key. (See the searching example earlier in this section, or turn to Sec. 6, Searching, for detailed instructions on POI searches.) After you have looked up an item with the Find Waypoint command, use or to make sure the GO TO command is highlighted at the bottom of the screen, then press ENT. The unit begins showing navigation information to the item. To cancel navigation, press MENU|MENU| to CANCEL NAVIGATION|ENT| to YES|ENT. The unit stops showing navigation information.

Alarms command (left); Alarm menu at right.
To change alarm settings: 1. Press MENU|MENU| to ALARMS|ENT|ENT. 2. Scroll or to select the desired category, then press ENT to check or clear the Enabled box. This turns the alarm on (checked) or off (unchecked.)
3. To change distance settings, scroll or to select the desired category, then press |ENT to activate the distance dialog box. Press or to change the first character, then press to the next character and repeat until the name is correct. 4. When your adjustments are finished, return to the last page displayed by repeatedly pressing EXIT. IMPORTANT ALARM NOTES: Anchor Alarm - The anchor alarm may be triggered even when you're sitting still. This typically happens when using small (less than.05 mile) anchor alarm ranges. Arrival Alarm - If you set the arrival alarm's distance to a small number and you run a route (see the Navigate Routes segment), this unit may not show navigation data to the next waypoint, once you arrive at the first one, since you may not be able to come close enough to the first waypoint to trip the arrival alarm.

Communications Port Configuration
The unit has one NMEA 0183 version 2.0 compatible communication port, or com port for short. The Com Port Menu, which is accessed from the System Setup Menu, lets you configure the communications port to send or receive data to another electronic device, such as an autopilot. The com port can be used for NMEA Binary data transfer. 70
Menus for changing Com Port settings.
For connectors and wiring information for another device, see page 14. For assistance in configuring the unit to communicate with another device, consult the factory; customer service phone numbers are in the back of this manual. Also see the entry below for Configure NMEA. To set Com Port Configuration: 1. Press MENU|MENU| to SYSTEM SETUP|ENT. 2. Press to COMMUNICATIONS PORT|ENT.

Configure NMEA

You can configure the unit to use specific NMEA sentences. 1. Press MENU|MENU| to SYSTEM SETUP|ENT. 2. Press to COMMUNICATIONS PORT|ENT| to CONFIGURE NMEA|ENT. 3. A menu appears showing the prefixes of the available NMEA sentences. A check mark next to a prefix means the prefix is in use. Use to select a prefix, then press ENT to turn off the prefix. (Press ENT again to check the box and turn a prefix on.) NOTE: The names of the NMEA sentences are abbreviated in this menu. These are the functions of the various selectable prefixes: GLL transmits latitude and longitude of present position, time of position fix, and status. RMC and RMB transmits navigation information messages. APB transmits autopilot information. GGA transmits time, position, and fix related data.

Configure a map fix so the unit can find your position on a printed chart or topographical map.
Press to SELECT ORIGIN|ENT|ENT|ENT to bring up the waypoint list. Select the waypoint (or a landmark of POI) that you saved the reference point under and press ENT. The unit displays a waypoint information screen with the command SET AS ORIGIN selected; press ENT and the unit returns to the Configure Map Fix menu. Finally, press EXIT to erase this menu. Now press to COORD SYSTEM|ENT, select MAP FIX from the list and press ENT|EXIT. All position information now shows as a distance from the reference point you chose.

Map Orientation

By default, this receiver shows the map with north always at the top of the screen. This is the way most maps and charts are printed on paper.
In Track Up mode, map shows "N" and arrow to indicate north.
Map orientation at left is shown in north up and at right, track up.
This is fine if you're always traveling due north. What you see to your left corresponds to the left side of the map, to your right is shown on the right side of the map, and so on. However, if you travel any other direction, the map doesn't line up with your view of the world. To correct this problem, a track-up mode rotates the map as you turn. Thus, what you see on the left side of the screen should always be to your left, and so on. Another option is course-up mode, which keeps the map at the same orientation as the initial bearing to the waypoint. When either the track-up or course-up mode is on, an "N" shows on the map screen to help you see which direction is north. To change map orientation: from the Map Page, press MENU| to MAP ORIENTATION|ENT. Use or to select the desired mode, then press ENT. Press EXIT|EXIT to return to the page display. NOTE: In North Up and Course Up, the present position arrow appears in the center of the map page. In Track Up, the position arrow appears centered in the lower third of the page.
NauticPath USA Marine Charts
Your unit can display NauticPath electronic charts on MMCs. They work just like a MapCreate custom map on a MMC. Nautical Chart Notes NauticPath charts contain notes or chart information, represented by circle-i Chart Note icons on the map display. An example is shown in the following figure.
