Compass Variance
Compass variance is the difference
between the earth's magnetic
north and the true geographic
north. Your vehicle's compass
should be pre-set to your zone.
If your vehicle is taken outside this
zone, it may be necessary to adjust
the compass to compensate for
variance.
To adjust for compass variance:
1. See your dealer to find out
what zone you are in.
2. Press and hold the on/off but-
ton for six seconds until ZONE
appears in the display.
3. Press the button again until
the correct zone number
appears in the display. The dis-
play will show a compass
direction within a few sec-
onds.
4. Calibrate the compass, if nec-
essary.
