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 drill-
ing 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.
NOTE:
The GPS antenna is inside the unit, so you must mount the unit in
a location with an unobstructed view of the sky.
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.
Power Connections
Your unit comes with a power/data cable that splits into three ends,
each with several exposed wires (shown in the following figure). The
end with 4 wires (blue, yellow, orange and shield) is a Data cable that
connects to a NMEA 0183 interface. The end with three wires (red,
black and shield) is a power cable that connects to a NMEA 2000
The thicker three-wire cable (red, black and white) is the Power Supply
for your unit (and optional external speaker connection for some units).
