Electronic Vehicle Information Center: Compass

WARNING: This page is about a different car, the 2003 Chrysler Concorde, 2003 Chrysler 300M, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

While in the C/T mode, the compass will display the direction in which the vehicle is pointed using the 8 major compass headings (Examples: north is N, northeast is NE). The self-calibrating compass unit requires no adjusting in normal use. The only calibration that may prove necessary is to drive the vehicle in 3 complete circles at 3-5 MPH (5-8 KM/H), on level ground, in not less than 48 seconds. This will reorient the compass unit to its vehicle.

The compass unit also will compensate for magnetism the body of the vehicle may acquire during normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on the fasteners that hold the overhead console assembly to the roof header can also affect compass operation. If the vehicle roof should become magnetized, demagnetize and recalibrate compass to restore proper compass operation.
