Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is up
to 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 adjustment.
Compass zone adjustment
1. Determine which magnetic zone
you are in for your geographic
location by referring to the zone
map.
2. Press and release the
SELECT/RESET stem to scroll
through the information menu until
the message center displays HOLD
RESET FOR SETUP MENU.

seconds to enter the compass zone adjustment mode.
