Compass Calibration
If after a few seconds the display does not show a
compass direction, (N for North for example), there may
be a strong magnetic field interfering with the compass.
Such interference may be caused by a magnetic
antenna mount, note pad holder, or similar object. If the
letter C appears in the compass window, the compass
may need to be reset or calibrated.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
Compass Variance
Compass variance is the difference between earth's
magnetic north and true geographic north. If the mirror
is not adjusted for compass variance, the compass
could give false readings.
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to
compensate for compass variance if the vehicle is
driven outside zone eight. Under certain circumstances,
such as a long distance, cross-country trip, it will be
necessary to adjust the compass variance.
