Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer to
Compass zone/calibration adjustment.
Compass zone/calibration adjustment
1. Determine your magnetic zone by
referring to the zone map.
2. Turn ignition to the ON position.
3. Start the engine.
4. From SETUP menu, select the
Compass/Odometer function.
5. Press SELECT to show the
current zone setting (XX).
6. Press the SELECT control
repeatedly until the correct zone
setting for your geographic location
is displayed on the message center.
The range of zone values are from
01 to 15 and “wraps” back to 01.

release the SETUP control.
Perform compass calibration in an open area free from steel structures
and high voltage lines. For optimum calibration, turn off all electrical
