2-78 Compass Variance
Compass variance is the difference between magnetic
north and geographic north. In some areas of the
country, the difference is great enough to cause the
compass to give false readings. If this occurs, the
compass variance must be set.

Compass/Temperature mode. Press the RESET button for
approximately five seconds. The last entered variance zone
number will be displayed. Press the MODE button until
the proper variance number, as shown on the map, is

zone and resume normal operation.
The display will show all the display segments for half a
second to acknowledge the change in zone number.

need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases ªCALº will be displayed, and all segments
of the compass will be illuminated where the compass
reading is normally displayed.
To calibrate the compass, in an area free from large metal
objects, make three 360
