Receiver Head

Stem Mount with 1 - 14 Thread
Follow these steps to stem mount the GPS receiver: 1. If you have a pre-existing stem mount, skip to step 2. If you need to mount the antenna pole (stem), determine the best location, preplan and test the cable routing to your Fishfinder unit before any drilling or cutting of your boat surfaces, then route the 20 (6 m) cable to the desired mounting location. Mark the location and drill a 3/4 (19 mm) hole for the cable and cable connector. If you have purchased hardware to stem mount your GPS receiver, follow the instructions included with that hardware to attach the stem to the boat.

Receiver Base

Antenna Stem
NOTE: 10 extension cables may be purchased from Humminbird if Stem Mount, Attaching your planned cable route exceeds 20 (6 m). Maximum cable length, Receiver Base to Stem including extension cables, should not exceed 50 (16 m). Visit our website at www.humminbird.com, or call our Customer Resource Center at 1-800-633-1468 to purchase extension cables.
2. Screw on the receiver base to the stem first, making sure that the stem pipe does not protude from the receiver base. This adds protection to the cable when pulling it through the pipe stem. In addition to this, deburr the pipe edges to reduce cable abrasion. 3. Use electrical tape to secure the NMEA pigtail to the cable as shown in the illustration.

NOTE: Leave the NMEA pigtail secured to the cable unless needed in order to make it easier to remove the GPS Receiver.

#6 - 1/4 Mounting Screws

4. Route GPS Receiver cable through the stem and continue with the planned cable route. 5. Attach the GPS Receiver to its base using the included #6 - 1/4 screws. Hand tighten only.

Cable Route Stem Stop

Access Under Mounting Location
Follow these steps to deck mount the GPS receiver when you can route the cable down through the mounting surface: 1. Determine the best location, then test route the 20 (6 m) cable from the Fishfinder control head to the planned mounting location of the GPS Receiver.
NOTE: 10 extension cables may be purchased from Humminbird if your planned cable route exceeds 20 (6 m). Maximum cable length, including extension cables, should not exceed 50 (16 m). Visit our website at www.humminbird.com, or call our Customer Resource Center at 1-800-633-1468 to purchase extension cables.
Attaching the Receiver to the Base, Making Sure Cable is Not Pinched
2. Mark the mounting location and drill a 3/4 (19 mm) hole for the cable and cable connector. Secure the NMEA pigtail to the cable with electrical tape. Route the cable. 3. Cover the cable hole with the GPS Receiver. Make sure the Receiver is flush against the surface and mark the two mounting holes with a pencil or awl. 4. Move the Receiver to the side and drill two pilot holes, using a 5/32 (4 mm) bit.

NOTE: Apply marine-grade silicone caulk or sealant to both screw and drilled holes as needed to protect your boat from water damage.
5. Align the GPS Receivers screw holes over the pilot screw holes and attach with the #6 - 3/4 Phillips head screws. Hand tighten only.
NOTE: If the mounting surface is thin or made of a light-weight material, you may need to add reinforcing material below the mounting surface in order to support the GPS Receiver.
No Access Under Mounting Location
Follow these steps to deck mount the GPS Receiver in a situation where you must route the cable to the side because there is no space for a cable underneath the mounting location. 1. Determine the best location, then test route the 20 (6 m) cable from the Fishfinder control head to the planned mounting location of the GPS Receiver.
2. Confirm that the cable length is adequate and route the cable from the Receiver to the Fishfinder control head. If holes are required to route the cable, they must be 3/4 (19 mm) to allow for the cable connector. Secure the NMEA pigtail with electrical tape.
NMEA Pigtail Taped to Cable
3. The GPS Receiver has two wire routing notches. Use the cable notch closest to the intended cable route. 4. With the cable routed, position the GPS Receiver in the planned mounting location and mark the mounting holes with a pencil or awl. 5. Move the GPS Receiver to the side and drill the two 5/32 (4 mm) pilot holes.
NOTE: Apply marine-grade sillicone caulk or sealant to both screw and drilled holes as needed to protect your boat from water damage.
6. Align the screw holes of the GPS Receiver over the pilot screw holes, referring to the illustration, and attach with the #6 - 3/4 Phillips head screws. Hand tighten only.
Finish Routing the Cable and Check Operation
Follow these steps to finish routing the GPS Receiver cable between the Fishfinder control head and the Receiver: 1. Secure the cable along its path to the Fishfinder control head as needed, using cable ties. 2. Plug the GPS Receiver cable to the Fishfinder control head per the instructions detailed in Connecting a GR16 GPS Receiver to the Fishfinder.

Before contacting the Humminbird Customer Resource Center, please read the following section. Taking the time to review these troubleshooting guidelines may allow you to solve a performance problem yourself, and therefore avoid sending your unit back for repair.
Fishing System Doesnt Power Up
If your Fishing System doesnt power up, use the Installation Guide that also comes with it for specific confirmation details, making sure that: the power cable is properly connected to the Fishing System control head, the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground the fuse is operational the battery voltage of the power connector is at least 10 Volts. Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacing the battery if necessary.

Fishing System Defaults to Simulator with a Transducer Attached
A connected and functioning transducer will cause the newly-started Fishing System to go into Normal operating mode automatically. If, when you power up the Fishing System, it goes into Simulator mode automatically, even though a transducer is already connected, this means that the control head is not detecting the transducer. Perform the following troubleshooting tasks: Using the Installation Guide that also comes with your Fishing System, check to make sure that the transducer cable is securely connected to the Fishing System. Reconnect if necessary, and power up the Fishing System again to see if this fixes the problem. Replace the non-functioning transducer with a known good transducer if available and power up the control head again. Check the transducer cable. Replace the transducer if the cable is damaged or corroded.

Display Problems

There are several main conditions or sources of possible interference that may cause problems with the quality of the information displayed on the control head. Look in the following table for some symptoms of display problems and possible solutions: Problem The control head loses power at high speeds. Possible Cause If the power output of your boats engine is unregulated, the control head may be protecting itself using its over-voltage protection feature. Make sure the input voltage does not exceed 20 Volts. The transducer position may need to be adjusted. A mix of air and water flowing around the transducer (cavitation) may be interfering with the inter-pretation of sonar data. See your Installation Guide for suggestions on adjusting the transducer position. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information. There are no fish detected, even when you know they are in the water under the boat, or sonar readings seem weak or faulty. Sonar readings may be affected if the transducer is not positioned correctly (i.e. mounted at an angle, not straight down), or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for proper sonar transmission, the bond between the transducer and the hull is not airtight, or because the transducer is dirty. Check with your Installation Guide for guidance on re-positioning the transducer, and make sure the transducer is clean. Low battery voltage may be affecting the power of signal transmission. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.

GPS & Navigation Glossary
Acquisition Time: The length of time that a GPS receiver typically takes to determine a position from at least three satellites. Humminbird GPS receivers provide very fast acquisition times (under one minute), permitting users to get out on the water faster. Alarm, Arrival: The audible alert that sounds when the boat is equal to or less than the alarm setting (25 feet3000 feet) from the location of the destination waypoint. Alarm, Drift: Drift Alarm is an audible alert that sounds when the boat is equal to or over the alarm setting (25 feet3000 feet) from the location where the alarm was turned on. Alarm, Off-Course: Off-Course Alarm is an audible alert that sounds when the boats distance from the intended Track, (Cross Track Error), is equal to or over the alarm setting (25 feet 3000 feet). See Track and Cross Track Error. Altitude: Altitude measures height above sea level. Altitude is a measurement that can be provided by GPS. Bearing (BRG): Bearing is the direction to a destination waypoint measured in degrees from North (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). Chartplotter: Chartplotter describes a navigation device that shows Present Position on a Map, along with Tracks, Waypoints, and Routes. All Chartplotters are also considered Trackplotters. All Humminbird GPS Combo units are Chartplotters. See Trackplotter. Cold Start: Cold Start refers to the procedure that a GPS receiver must perform when it does not have historical information regarding its current location. This procedure typically lasts for several minutes, and may be experienced upon first power up of the receiver, or if the receiver has been moved a great distance. Course Over Ground (COG): Course Over Ground is the current direction the boat is traveling measured in degrees from North (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). When the Course Over Ground is equal to Bearing, the boat is said to be On Course and will arrive at the destination in the most efficient manner. COG is often confused with Heading. See Heading. Cross Track Error (XTE): Cross Track Error is the straight-line distance of the boat from the intended Track. XTE measures how far the boat is off course, and also triggers the Off Course Alarm. See Track. Differential GPS (DGPS): Differential GPS is a system to improve the position accuracy of the Department of Defense GPS through the use of secondary correction signals broadcast from

ground stations around the coastal United States and on some inland waterways. These correction signals are provided by the USCG and received by an auxiliary Differential Beacon Receiver (DBR) that connects to the GPS receiver. The advent of WAAS has largely negated the need for the added expense of a DBR in the United States. Distance To Go: Distance To Go is the straight-line distance between Present Position and the Destination Waypoint. DTG and SOG (Speed Over Ground) are used to calculate Time To Go. See Time to Go and Speed Over Ground. Estimated Position Error (EPE): Estimated Position Error is a calculation that indicates the potential position inaccuracy the user may experience due to a variety of GPS factors which include satellite position in the sky, signal strength and others factors. Fix Type: Fix Type indicates whether the GPS receiver is providing 2D fix or 3D fix. A 2D fix requires only three satellites and provides only latitude and longitude. A 3D fix requires four or more satellites, and provides latitude, longitude and altitude. GPS: GPS is an acronym for Global Positioning System. GPS provides accurate position (latitude, longitude, altitude) information virtually anywhere on the earth through satellite technology and personal receivers on the ground. A series of geosynchronous satellites broadcast a unique signal toward the earth once per second. A GPS receiver, such as that included with many Humminbird products, receives the signals from these satellites and is able to determine position based on very slight differences in the time each signal is received and the receivers knowledge of the location of each of the satellites. Heading: Heading describes the direction the boat is pointing and is measured in degrees (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). Due to wind and waves, the boat is often traveling in a slightly different direction than it is heading, and therefore Heading is often confused with Course Over Ground. See Course Over Ground. Map Datum: A Map Datum refers to a particular survey of the earths surface that was referenced when creating a chart (i.e. WGS84). Since the earth is not flat, and not even consistently round, a mathematical model must be used to translate coordinates from the sphere of the earth to the flat surface of a chart. This mathematical model is the Map Datum. Historically, many different Map Datums have been used around the world to create maps; often a reference to the Map Datum can be found in the legend of a paper map. It is important to select the correct Map Datum setting in your fishfinder when comparing GPS position to a paper chart to avoid slight position inaccuracies. Almost all electronic charts use the WGS84 Map Datum and therefore, they do not require setting changes. MMC: MMC is an acronym for Multi Media Card. An MMC is a postage stamp-sized memory device used to store electronic data such a maps, waypoints, routes and other information.

across a given distance, and is the speed measurement provided by GPS. An alternate, Speed Through Water, is provided by a speed paddlewheel, and is the measurement of the flow past the boat, which may vary depending on current speed and direction. Speed Over Ground is optimal for navigation because accurate destination times can be derived from this measurement. Humminbird products allow for input and display of both speed measurements. Time To Go (TTG): Time To Go is the estimated time required to reach the destination waypoint. TTG is calculated using the SOG and DTG. See SOG and DTG. Track: A Track is a series of saved points that define the past path of the boat. These Track Points are saved at regular time intervals. Tracks are a useful and quick method to see where youve been, and an easy guide to follow to get you back to the starting point. Generally, all GPS units have a limited number of Track Points that can be saved before the unit runs out of memory and begins erasing the first track points saved. Because of this, the user can adjust the Track Point Interval menu to increase the amount of time between when points are saved, and thus extend the distance covered by a track. Tracks can also be permanently saved to memory, and re-displayed at the users option. Track Line (TRK): The Track Line is the desired line of travel between two waypoints, and represents the most efficient path between the two points because it is a straight line. The TRK is measured in degrees (i.e. 321, where 000 is North, 090 East, 180 is South, 270 is West). See Cross Track Error, Course Over Ground. Trackplotter: Trackplotter describes a navigation device that shows Present Position, along with Track, Waypoint, and Routes, but NO MAP in the background. See Chartplotter. Trolling Grid: Trolling Grid is a Humminbird feature that displays a precise reference grid around a waypoint. This grid is used as a guide pattern for trolling around a specific area to assure a more efficient and complete coverage of that area. Trolling Grid resolution be changed by zooming in or out on the chart. The Trolling Grid can also be rotated on the display to orient it for optimal boat course for wave and wind conditions. UTC: UTC is an acronym for Universal Time Constant. UTC is the standard time used in navigation, and is the local time in Greenwich England. (UTC is equivalent to Greenwich Mean Time (GMT)). To display the correct Local Time in a Humminbird GPS unit, the user must use the Local Time Zone menu and select the time zone (i.e. EST, CST). WAAS: WAAS is an acronym for Wide Area Augmentation System. WAAS is complementary technology to GPS that provides enhanced accuracy through correction signals broadcast from Federal Aviation Administration WAAS satellites stationed over the USA. These secondary signals are automatically received by the standard Humminbird GPS Receiver. With WAAS

signal, GPS accuracy is improved to within 3 meters 95% of the time. Outside the United States, regional governmental coalitions have created similar systems such as EGNOS (Europe) and MSAS (Japan). Waypoint: A Waypoint is the saved location (latitude, longitude) of a point of interest that is stored in a GPS receivers memory. This can include a marker buoy, dock, fishing hole or anywhere else the user may want to return to. Humminbird products offer the ability to name and assign a symbol to the saved location. Depth, Date and Time of Day when the waypoint was created is also saved. Waypoint Target: Waypoint Target is a Humminbird feature that displays a precise bulls eye around a selected waypoint. This bulls eye is used to easily monitor boat position relative to a waypoint, and is useful for fishing over submerged structure. With Waypoint Targets, a quick look at the screen lets you know how far off the waypoint the boat has drifted.
