After pressing the "Compass Settings" button on the touchscreen the following settings will be available:
NOTE: Before compass calibration is performed, the compass variance zone should be set for best results.
Press "Compass Variance" on the touchscreen to change this setting. You will then be able to select a compass variance of 1 through 15 per the compass variance zone map figure.
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 being driven, illustrated in the zone map.
Once properly set, the compass will automatically compensate for the differences when calibrated, and provide the most accurate compass headings.

Press "Compass Calibration" on the touchscreen to enter calibration. To start calibration of the compass, press the "YES" button on the touchscreen and complete one or more 360-degree turns (in an area free from large metal or metallic objects). A message will appear on the touchscreen when the compass has been successfully calibrated.
NOTE: Keep magnetic materials away from the top of the instrument panel, such as Mobile Phones, Laptops 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.
