COMPASS CALIBRATION MODE:
Setting the Compass
The compass is self-calibrating, which eliminates the
need to manually set the compass.
However, under certain circumstances, such as during a
long distance cross-country trip, it will be necessary
to compensate for compass variance and reset the zone
through the DIC.
Compass variance is the difference between earth’s
magnetic north and true geographic north. If not
adjusted to account for compass variance, the compass
in your vehicle could give you false readings.
In order to do this, you will have to set or calibrate the
compass to the variance zone in which you are located.
