Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To ensure compass accu-
racy, the compass variance should be properly set accord-
ing to the variance map for the zone where the vehicle
will be driven. When properly set, the compass will
automatically account for this difference.

NOTE:

• A good calibration requires a level surface and an

environment free from large metallic objects such as
buildings, bridges, underground cables, railroad
tracks, etc.

• 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 com-
pass readings.
