Setting The Compass Variance And Compass
Calibration
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: 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.
To Set the Variance: with the ignition in the ON position,
with a short button press (less than one second) press and
release the EVIC button several times until you have
displayed the “Personal Settings (Customer-
Programmable Features)” menu. Once in the “Personal
Settings (Customer-Programmable Features)” menu,
press and release (less than one second) the EVIC button
