wiring diagram on page 41 for connecting the unit to
NMEA compatible devices.
To install the wiring harness to a GPS or
other NMEA device:
1. Follow the voltage source installation steps
(see page 40). For Garmin units, the ground
(Black) wires serve as NMEA ground and must
be attached together or on the same terminal.
Refer to the wiring diagram of your GPS unit
for wire identication.
2. Connect the Blue (NMEA Out 1) wire from the
unit to the NMEA In wire on the NMEA unit’s
wiring harness, and the brown (NMEA In 1)
wire to the NMEA Out wire on the NMEA unit’s
wiring harness.
3. Repeat step 2 using the Grey and Violet wires
for an additional NMEA unit.
4. Set the unit’s serial port(s) to use NMEA In/
NMEA Out

Installing the Unit to a Garmin CANet
GPSMAP 2008 is a CANet-compatible Garmin device,
and can send or receive sonar information from another
CANet-compatable Garmin device. Using the CANet
optimizes the performance of CANet-compatible
units, allowing sonar information from a Sounder
orFishndertobesharedwithuptotwoCANet
compatible Garmin GPS units. A standard NMEA
connection only allows depth, temperature, and speed
