Compass 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 heading.
NOTE: Magnetic materials should be kept away from the top of the right rear quarter window. This is where the compass sensor is located.
