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 CAL
appears in the compass window, the compass may
need to be reset or calibrated.
To calibrate the compass:
1. Make sure CAL is displayed. If CAL is not
displayed, press and hold the compass button until
CAL displays.
2. While CAL displays, drive the vehicle in circles at
5 mph (8 km/h) or less until the display reads a
direction.
Compass Variance
The mirror is set to zone eight. If you do not live in zone
eight or drive out of the area, the compass variance
needs to be changed to the appropriate zone.
To adjust for compass variance:
1. Find the current location and variance zone
number on the following zone map.
2. Press and hold the compass button until a Z and a
zone number displays.
3. Once the zone number displays, press the
compass button repeatedly until the correct zone
number is reached. If CAL displays in the compass
window, the compass may need calibration. See
“Compass Calibration” listed previously.
