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 map to determine the correct zone. The zones are numbered 1 through 15. While the DIC is in the COMPASS ZONE item, the DIC will display the current compass zone. Depressing the Set/Reset button will scroll through the available compass zones. Depressing the Set/Reset button for a few seconds will select the displayed compass zone.
You cannot reset the Compass/Temperature mode. This mode is retained during ignition OFF.
