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.
Interference can 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 very
slowly, in circles, until the display reads a direction.
Compass Variance
The mirror is set in zone eight. It is 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 is necessary to adjust the compass variance.
To adjust for compass variance:
1. Find your current location and variance zone
number on the zone map that follows.
2. Press and hold O until a zone number displays.
3. Once the zone number displays, press
O
repeatedly until the correct zone number is
reached. If C appears in the compass window, the
compass may need calibration. See “Compass
Calibration” listed previously.
