FORD 2005 Expedition v.3 - Manual (Page 136)

Compass display
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antenna. Magnetic
or metallic objects placed in, on or near the vehicle may also affect
compass accuracy.
Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. Refer to Compass zone/calibration
adjustment.
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 Info menu, select the
Compass/Odometer function. (Do
not select Trip, DTE, or AFE. The
top of the message center must be
blank).
5. Press and release the RESET
control until the message center
display changes to show the current
zone setting (XX).
6. Press and release the SETUP
control repeatedly until the correct zone setting for your geographic
location is displayed on the message center. The range of zone values are
from 1 to 15 and “wraps” back to 1.
