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.
