Compass Magnetic Variation Adjustment
Compass Magnetic Variation Adjustment:
Compass variation is the difference between magnetic north and geographic north. In some areas of the country the difference is great enough to cause the compass to give a false reading. If this occurs, the compass variance must be set. View the Variance Zone Display to determine the correct zone. The zones are numbered 1 through 15. Depress and hold both the MODE and the E/M buttons simultaneously while the DID is in the Compass/Temperature mode. After 5 seconds, the DID will display the current variation setting. Release the buttons and adjust to the correct variation number using the E/M button. Consult the map for variation zone numbers. When the desired variation is reached press the MODE button to accept.
You cannot reset the Compass/Temperature mode. This mode is retained during ignition OFF.
