GHP 10V Repeatedly Fails Compass Calibration

If a compass calibration is failing every time it is performed, there are a few troubleshooting steps to follow.

The first troubleshooting step would be to make sure there is nothing causing interference with the compass ball. The compass ball should be mounted at least 24 inches away from magnetic materials, steel objects, speakers, electric motors, or high-current wires. A way to test a location of a mounting location for the compass ball is to use a handheld compass. Hold the handheld compass in the area where the compass ball is to be mounted. If the handheld compass does not show any signs of interference, the compass ball can safely be mounted in that location.

Another troubleshooting step for this problem is wiring. The GHP 10V Gateway uses a five pin male connector to connect to the GHP 10V's compass ball. The five pin cable that comes out of the Volvo Gateway can plug directly into the GHP 10V's compass ball, however this is not the correct location. The 5 pin female connector on the GHP 10V's compass ball is used for a NMEA 2000 connection. The Volvo Gateway's five pin male connector will need to be plugged into the interconnect cable from the Compass ball.
