Mark II Navigation System Calibration

The calibration procedure of the Mark I system is not required with the Mark II system. This system self calibrates automatically as the vehicle is driven after following the steps below.

• System must be fully functional with no faults present in fault memory.
• Correct Map data base CD installed for your.
• Vehicle outside with an unobstructed overhead view. Switch ignition on and allow system adequate time to receive a minimum of three GPS signals. This is confirmed by the green GPS indicator in the map display.
• Set the map display to the 400' scale and drive the vehicle on digitized roads. Make frequent turns at intersections where possible.

While driving, the system utilizes the map CD, the received GPS coordinates, the Gyro sensor to determine turn activity and the wheel speed sensor input. It compares all of these variables and automatically pinpoints the vehicle position.
