Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences and provide the most accurate compass head-
ing.
NOTE: Keep magnetic materials away from the top of the
instrument panel, such as iPod’s, Mobile Phones, Lap-
tops, and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.
