Section 2:
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 power cable. This will help you make
sure you have enough cable length for the desired configuration.
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.
The IntelliMap 502C uses an internal antenna to achieve a GPS
lock. In order to get a strong signal, you need to select a mount-
ing location that has a clear, unobstructed view of the sky.
NOTE:
The IntelliMap 502C is designed for open-cockpit boats, but the
unit will probably work in an automobile or a closed-cockpit boat if
it's mounted with a clear view through the windshield or other win-
dows. This probably will not work if you have a cab-over design
pickup truck camper or motor home, or a boat cabin with limited
visibility. Remember, for optimum operation, this unit should be
mounted in the open with nothing obstructing its view of the sky.
Power Connections
The IntelliMap 502C works from a 12-volt battery system. For the best
results, attach the power cable directly to the battery. You can attach
the power cable to an accessory or power bus, but you might have
problems with electrical interference. Therefore, it's safer to go ahead
and attach the power cable directly to the battery.
CAUTION:
When using the unit in a saltwater environment, we strongly rec-
ommend that you shut off the power supply to the power cable when
the unit is not in use. When the unit is turned off but still connected
to a power supply, electrolysis can occur in the power cable plug.
