Compass Variance
Compass Variance is the difference between magnetic
North and geographic North. To allow the compass
module to compensate for that difference and ensure
accuracy, you can set the variance in the compass module
to the zone where the vehicle is located according to the
Compass Variance Map. To set the variance, perform the
following steps.
NOTE:
The default variance setting is Zone 8. When setting
the variance, the numbering will wrap around from
Zone 15 to Zone 1.
Magnetic materials should be kept away from the top
of the instrument panel, as this is where the compass
sensor is located.
