Compass Settings — If Equipped
After pressing the “Compass Settings” button on the
touchscreen the following settings will be available:
• 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:
Keep magnetic materials away from the top of the
instrument panel, such as iPod’s, Mobile Phones, Lap-
tops and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.
• Perform Compass Calibration
Press the “Calibration” button on the touchscreen to
change this setting. This compass is self-calibrating,
which eliminates the need to manually reset the compass.
When the vehicle is new, the compass may appear erratic
until it is calibrated. You may also calibrate the compass
