Installation & Accessories
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 cables for the antenna and power.
This will help you make sure you have enough cable length for the de-
sired configuration.
2. Determine the approximate location for the GPS antenna module
and its cable route.
3. Determine the location of your battery or other power connection,
along with the power cable route.
4. Install the GPS antenna and route the antenna cable to the GPS
unit.
5. Install the power cable and route it to the GPS unit.
6. Mount the GPS unit.
GPS Antenna/Receiver Module Installation
The GlobalMap 4000M package includes the LGC-12w GPS module. This
device contains the GlobalMap 4000M's external antenna and receiver
for GPS and WAAS signals. The antenna/receiver module comes with a
25-foot extension cable. This module can be mounted on a flat surface or
pole, or a magnet is included for temporary mounting on any ferrous sur-
face.(The LGC-12s GPS module sold with earlier Lowrance equipment
will work with your unit, but it will not receive WAAS signals.)
