Compass Variance Adjustment

COMPASS VARIANCE ADJUSTMENT





Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and true geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this problem occurs, the compass variance must be set.

NOTE: If the vehicle is taken on long trips into a new variance zone the compass function may be effected. Compass variance will need to be updated to the new zone number to function properly.

NOTE: The default for the compass variance from the factory is 8.

Set the compass variance manually as follows:





1. Using the Variance Settings Map, find your geographic location and note the zone number.
2. Turn the ignition switch to the ON/RUN position.
3. Using the U-Connect Touch (TM) screen, select SETTINGS either from the hard controls on the side of the screen, or from the menu selections at the bottom of the screen, depending on model.
4. Scroll through the menu, and select COMPASS VARIANCE.
5. Once selected, toggle through the zone numbers (1-15), until the zone number for your geographic location appears in the display. The zone number will set automatically.

NOTE: The default for the compass variance from the factory is 8. During programming, the Zone value will wrap around from Zone 15 to Zone 1.

6. Press the BACK button to return to the main menu.
7. Confirm that the correct direction is now indicated by the compass.
