Compass: Adjustments
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.
To set the compass variance:
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. If the compass/temperature data is not currently being displayed, momentarily depress and release
the C/T push button to step through the display options until you have reached the compass/temperature display.
3. Press and hold the Reset push button down until "VAR" appears in the display. This takes about five seconds.
4. Momentarily depress and release the STEP push button to step through the zone numbers (1-15), until the zone number for your geographic
location appears in the display.
5. Momentarily depress and release the Reset push button to enter the displayed zone number into the compass unit memory.
6. Confirm that the correct directions are now indicated by the compass.
