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 and battery powered devices, (such as
cell phones, iPod’s, radar detectors, PDA’s and laptops)
should be kept away from the top of the instrument
panel. This is where the compass module is located and
such devices may interfere and cause false compass
readings.
