GPSMAP 6000/7000 Series Installation Instructions 15
Wiring to a Lamp or to a Horn (Optional)
The GPSMAP 6000/7000 series chartplotter can be used with a lamp, a horn, or both, to sound or ash an alert when the chartplotter displays a
message. The alarm does not need to be wired for the GPSMAP 6000/7000 chartplotter to function. The alarm circuit switches to a low-voltage
state when the alarm sounds. The maximum current is 100 mA, and a relay is needed to limit the current from the chartplotter to 100 mA. To
manually toggle visual and audible alerts, install single-pole, single-throw switches.

Wiring to a GPS 17 or GPS 17 HVS Antenna
If you already have a Garmin GPS 17 or GPS 17 HVS installed on your boat, you can wire it to the GPSMAP 6000/7000 series chartplotter
instead of installing the included GPS 17x. Wire the existing GPS 17 or GPS 17 HVS antenna to the included 19-pin NMEA 0183 cable as well
as to the power supply for the boat, referring to the diagram below. Use 22 AWG shielded wiring for extended runs of wire to the NMEA 0183
cable or GPS 17 HVS cable. Solder all connections and seal them with heat-shrink tubing.
NOTE: If you are using more than one Garmin chartplotter over a Garmin Marine Network, do not wire more than one chartplotter to a GPS
antenna. The GPS signal is shared between multiple chartplotters connected to a Garmin Marine Network.
