You need to select an antenna installation location that has a clear, un-

obstructed view of the sky. After the module is installed, connect it to the 

unit. The LGC-3000 can communicate with your GPS unit either directly 
(using the supplied extension cable) or through a NMEA 2000

® 

 network. 

See the module’s instruction sheet, publication part number 988-

0154-651, for complete installation instructions. 

In an automobile, you may achieve good results by simply placing the 

external antenna on the top of the dash, at the base of the windshield. A 

piece of the rubber non-skid shelf liner material available in recreational 

vehicle supply stores will help hold the antenna in place. This may not 

work well if you have a cab-over design pickup truck camper or motor 

home. If dashboard reception is poor, simply relocate the antenna module 

elsewhere on the vehicle for a clearer view of the sky. 

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

each with several exposed wires. 
The thicker two-wire cable (red and black) is the power supply for your 

display unit. This cable has no label. 
The 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 5 wires (blue, yellow, orange, green and shield) is a data 

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

ports. These allow your unit to exchange NMEA 0183 data with another 

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