Your unit packs with the LGC-3000 GPS module. This device contains 

the unit's external antenna and receiver for GPS and WAAS signals. 

The antenna/receiver module comes with a 15-foot (4.6 m) extension 

cable. This module can be mounted on a flat surface or pole, or an op-

tional magnet is available for temporary mounting on any ferrous sur-

face.  
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. 

To use the module 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 avail-

able 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. 

A network bus is an installed and operational network cable (backbone) 

running the length of your boat, already connected to a power supply and 

properly terminated. Such a bus provides network connection nodes at 

various locations around your boat. The NMEA 2000 network is similar to
