Warnings and Precautions

Introduction
MAP DATA INFORMATION: One of the goals of GARMIN is to provide customers with the most complete and accurate cartography that is available to us at a reasonable cost. We use a combination of governmental and private data sources, which we identify as required in product literature and copyright messages displayed to the consumer. Virtually all data sources contain inaccurate or incomplete data to some degree. This is particularly true outside the United States, where complete and accurate digital data is either not available or prohibitively expensive.
WARNING: For use in vehicles, it is the sole responsibility of the owner/operator of the eMap to secure the GPS unit so that it will not interfere with the vehicles operating controls, obstruct the drivers view of driving conditions, or cause damage or personal injury in the event of an accident. Do not mount the eMap over air bag panels or in the field of air bag deployment. AIr bags expand with a rapid force that can propel objects in their path toward the driver or passengers, causing possible injury. Refer to air bag safety precautions contained in the vehicle owners manual. Do not mount the eMap in a place where the driver or passengers are likely to impact it in an accident or collison. The mounting hardware provided by GARMIN is not warranted against collision damage or the consequences thereof.

NOTE: you a. CD-ROMIf and ahave purchased useMapSource Data Card for with the eMap, refer to page 10 for Data Card installation and map data transfer instructions. For more information about MapSource, refer to Appendix G.
Start Up The eMap To Start Up the eMap, take the unit outside and find an open area where the built-in antenna has a clear view of the sky. Hold the receiver at a comfortable height with the front of the eMap pointing up. Press and release the POWER key to turn the eMap On. The Title Page and Information Pages will be displayed, and then followed by the Map Page.

Start Up

The Title Page followed by information pages will be displayed when the eMap is turned on.

Getting Started

Each time you turn on the eMap it must determine its location. The first time you use your eMap, this may take from five to fifteen minutes. After first use, the eMap should determine your location in less than one minute. When your location has been determined, the Compass in the upper left corner of the Map Page will display Cardinal letters (North, South, East, West) and your current location will be shown on the map beneath it. If there are not enough satellites in view to determine its location, the eMap will display a Poor Satellite Reception message with four options. A brief explanation for each option will appear when it is highlighted. Use the ROCKER keypad to highlight the logical option and then press the ENTER key to activate it. If the time displayed in the time field on the Map Page is not correct, you will need to set the time zone for your current location. Detailed instructions for setting the time zone are contained on pages 32 and 40 of this manual. About the Map Page The Map Page is the main operating page of the eMap. It graphically shows you map details, your current location, marks your route to a destination with a route line, and leaves a trail (track log) of where youve been. It tells you what direction to go or the direction you are traveling. It tells you your speed, the distance you have traveled, or the distance to travel, and the time of day or the time remaining before reaching a destination.

Getting Started Using the Map Page
Using the Map Page to Navigate The Map Page provides graphic display for the four methods of eMap navigation: Goto - A direct path to a map location, (waypoint, city, address, etc.) Track - A previous path of travel that has been stored (logged) in the eMap. A Track allows you to repeat a path or to return to your starting point on the same path using the GARMIN TracBack feature. Route - A path to a destination consisting of landmarks along the way (waypoints, cities, highway exits, points of interest, intersections, etc.) Travel when not on a Goto, Track or Route - This is best described as travel without entering a destination in the eMap. The Map Page displays your real time movement as you travel with the unit turned on and receiving satellites. It can be saved (logged) as a Track. Data Fields Several Data Fields support the Map Page and consist of the following elements. Direction Fields There are three types of direction fields, each providing direction information dependent on whether you are stopped while navigating, navigating to a destination, or traveling without a recorded destination. Direction To Go (N. S. E. W.) - Cardinal letters indicate the direction to go when starting out or to resume after having stopped while on an active Goto, Track or Route. These letters can be changed to degrees. Refer to page 33. Direction To Go (Arrow) - An arrow that points to the direction you should be traveling when moving on an active Goto, Track or Route. Compass - A compass that shows the direction you are moving when not on a an active Goto, Track or Route.

To adjust the screen contrast, use the LEFT or RIGHT ROCKER keys to move the contrast adjustment lever.

Contrast Settings

Using the Backlighting Feature You may turn on the screen backlighting for easy viewing in dim and dark lighting conditions. The backlight is set at the factory to turn Off after 15 seconds to extend battery life. To select from shut-off time options, refer to the section on Setup Options. To turn the backlighting On and Off:
1. Press and release the BACKLIGHT/CONTRAST key to toggle the backlight ON and OFF. 2. You can also turn the backlight function ON or OFF by pressing and holding the BACKLIGHT/ CONTRAST key until the Backlight/Contrast window appears. Then, press the ROCKER keypad UP for ON or DOWN for OFF.

Backlighting

Use the UP or DOWN Rocker keys to move the Backlighting switch up for ON or down for OFF.
If set for automatic time-out, it will shut-off automatically after the last key press. Pressing any key will reactivate the backlight. If the timeout is set for Stays On it will not turn off. Extended use of backlight will significantly reduce battery life. Setting the Correct Time If the time displayed in the Time field of the Map Page is not the correct time for your Time Zone, you will need to set the time. Refer to Time Settings on page 32. What Beeper Tones Mean The eMap Beeper produces three types of signals. Single Beep - Indicates that a key has been pressed. Two Beeps - Indicate that a message has been displayed with information about unit operation. Multiple Beeps - Indicate an incorrect key press. Refer to Beeper on page 32 for detailed information.

How to Construct a Cable for the Garmin eTrex or eMap
Thank you for obtaining a GPS connector for the Garmin eTrex or eMap receiver from us. This document will provide you with the information you need to construct virtually any type of cable you may require, whether you want to connect your GPS to a computer, or to provide power to your GPS. Technically, a GPS to GPS cable could also be constructed, but it appears as though the eTrex/ eMap receivers do not have the capability to initiate a data transfer. Please remember that this information is provided without warranty of any kind. Though every effort is being made to ensure that the information is accurate, we cannot be held responsible for any errors or omissions. If you construct a cable that doesnt work (or even worse, damages your GPS, computer, or yourself) as a result of a mistake in these instructions, we would appreciate learning about the error so that it can be fixed, but we cannot be held liable for any damages.
Connector Pinouts and Signals
Diagrams represent the view of the connector as seen from the side that plugs into the computer or GPS. In other words, this is the side of the connector that you do NOT attach wires to. Keep this in mind when constructing your cable.

A note about supplying power to your GPS
The eTrex and eMap GPS receivers operate from two 1.5 volt batteries, and expect a similar voltage when external power is applied. You can use the connectors to supply power to your GPS (in addition to data, if required), but please ensure that no more than 3.3 volts DC is applied. A voltage higher than this will almost certainly damage your GPS. This means that you cannot power your GPS directly from a 12 VDC lighter adapter plug unless you provide a voltage regulation circuit to bring down the voltage to somewhere in the range of 33.3 volts. For sample schematics, please visit http://www.nomad.ee/micros/etrex.shtml Alternately, you may want to consider a prebuilt power inserter cable that we carry. In the instructions that follow, if you wire up an IBM data cable with a female DB9 serial connector, and also connect the power pin (pin 4) of the eTrex connector to pin 8 on the DB9 serial connector, the data cable that you build will be compatible with our power inserter. The power inserter can be daisy chained with your data cable to provide data transfer capability with your receiver, while simultaneously providing power via a car lighter adapter. Please visit http://www.syz.com/gps/ for more information on our power inserter cable.

Assembling the Connector

The separate parts making up the connector are shown below (the two plastic halves are shown from the inside).

Mini Din-8

Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 Simply solder or crimp wires from a four conductor cable to each of the four clips, and line them up in the right hand piece with the spring ends protruding through the slots to the outside of the connector, keeping track of which wire is going to which spring clip.

Then, snap the two plastic halves together. Slide the ring over the cable and fit it onto the connector. This will help to hold everything together. The finished GPS end of the cable should appear as follows:
Constructing a Data Cable for the IBM with a DB-25 Serial Connector
First, determine whether or not you need a male or female DB25 to plug into the serial port of your computer. Use the pinout diagrams on the preceding page for the DB-25 and GPS connectors, and connect the following pins: GPS Pin 3 (RxD) Pin 2 (TxD) Pin 1 (Gnd) DB-25 Pin 2 (TxD) Pin 3 (RxD) Pin 7 (Gnd)
Now, you can solder or crimp the wires from the cable to the appropriate pins on your serial connector (DB-9, DB-25, or Mini DIN-8). Refer to the Connector Pinouts and Signals diagrams on the reverse side as this page, as well as the following electrical construction guidelines to wire your connector appropriately. If you do wish to provide power to your GPS, the power ground is shared with the signal ground. Ensure that the power you provide the unit with is limited to 3.3 volts DC, as mentioned, and provide an inline fuse so that if something shorts out, your cable, computer, or GPS is not damaged. The little plastic tab protruding from the end of the finished connector will snap into the hole just below the eTrex socket on your receiver to provide for a more secure fit. If youre using an eMap, just clip off the tab.

Constructing a Data Cable to connect two Garmin GPS receivers
Obtain 2 GPS connectors and wire them as follows: GPS 1 Pin 3 (RxD) Pin 2 (TxD) Pin 1 (Gnd) GPS 2 Pin 2 (TxD) Pin 3 (RxD) Pin 1 (Gnd)
Constructing a Data Cable for the Macintosh
The Macintosh serial port can deal with either RS-232 or RS422 signals, and uses the Mini DIN-8 connector. Wire the cable as follows: GPS Pin 3 (RxD) Pin 2 (TxD) Pin 1 (Gnd) Mini DIN-8 Pin 3 (TxD-) Pin 5 (RxD-) Pin 4 (Gnd)
Constructing a Data Cable for the IBM with a DB-9 Serial Connector
First, determine whether or not you need a male or female DB9 to plug into the serial port of your computer (most will require female). Use the pinout diagrams on the preceding page for the DB-9 and GPS connectors, and connect the following pins: GPS Pin 4 (V+) Pin 3 (RxD) Pin 2 (TxD) Pin 1 (Gnd) DB-9 Pin 8 (used for opt. Power Inserter) Pin 3 (TxD) Pin 2 (RxD) Pin 5 (Gnd)
If your GPS emits a true RS-232 signal (most dont), tie Pin 8 on the Mini DIN-8 to Pin 4 to ground it.
