You can install the GPS system in some other order if you prefer, but 

we recommend this installation sequence: 
Caution: 

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. 

Your unit comes with a power/data cable that splits into three 

branches, each with several exposed wires. 
The thicker three-wire cable (white, red and black) is the power supply 

for your display unit. This cable has no label. 
The thinner branch with three wires (red, black and shield) is the 

power cable for a NMEA 2000 network. It is labeled "NMEA 2000 

POWER."  
The branch with four wires (blue, yellow, orange, and shield) is a data 

cable, labeled "RS-232 COMM." It supports a serial communication 

port. This allows your unit to exchange NMEA 0183 data with another 

device, such as an autopilot, DSC marine radio or computer.
