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 head-
ing.
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.
