Jeep 2013 Wrangler - Owner Manual - Manual (Page 323)

Compass/Temperature Display
NOTE: If the vehicle is equipped with a Chrysler
Uconnect® gps (Navigation Radio), the NAV system will
provide the compass direction, and the variance and
calibration menus will be unavailable. The compass will
perform accurately, based on GPS signals instead of the
Earth’s magnetic field.
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 differ-
ences and provide the most accurate compass heading.
