For complete instructions on setting up a new NMEA 2000 network or 
expanding an existing one, see the other document packed with your 
LGC-3000 GPS module, "Setup and Installation of NMEA 2000 Net-
works, General Information,
" part number 988-0154-173. If that docu-
ment is missing, it can be downloaded free from the Lowrance web site. 
Mounting 
The GPS module can be mounted on any flat surface, provided there is 
access behind the mounting surface for the screws. The optional mag-
net allows the module to be easily used on cars or off-road vehicles. The 
optional pole mount adapter lets you mount the antenna on a pole or 
swivel mount that uses standard marine 1"-14 threads. 
Surface Mount 
The GPS module can be easily installed on any flat surface that is at 
least 3-1/2" (90 mm) wide. Be sure that a clear, unobstructed view of 
the sky is available at the selected location. GPS signals travel "line-of-
sight" at very high frequencies, so nearly anything blocking the an-
tenna can stop the unit from finding a satellite. 
Caution: 
Do not mount the GPS module in the direct path of a radar an-
tenna's beam. Radar radiates high-energy signals that can in-
terfere with GPS signal reception. 
In an automobile, you may achieve good reception 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 recrea-
tional 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. 
Once you’ve determined the mounting location, use the template on the 
following page to drill the screw holes. The screws supplied with this 
unit are about 1-1/8" long (4 mm x 30 mm). Drill 3/16" (4.75 mm) holes 
for the mounting screws. 
If you need to route the cable through the mounting surface, drill a 7/8" 
(22 mm) hole for the cable's connector. The notch in the antenna hous-
ing allows the cable to pass through, if desired, instead of routing it 
down through the mounting surface. 
After drilling the holes, pass the O-ring over the cable and press it into 
the groove on the bottom of the antenna housing. (If you are using the 
housing notch to route the cable outside, you may need to cut a notch in
