Variance Settings |
NOTE: If the vehicle is taken on long trips into a new variance zone the compass function may be effected. Compass variance may need to be adjusted to the new zone number to function properly.
NOTE: The default for the compass variance from the factory is 8.
Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give inaccurate readings. To optimize compass accuracy, the compass variance should be properly set according to the compass variance map zone for the region that the vehicle is in.
To set the compass variance:
NOTE: During programming, the Zone value will wrap around from Zone 15 to Zone 1.
NOTE: The US/Metric display will change from English to Metric or Metric to English before the “VAR” symbol appears, however, it will return back to the original US/Metric setting after programming the compass variance.
