If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic CB
or cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle,
move the magnetic item, then turn
on the vehicle and calibrate the
compass.
To calibrate the compass, use the
following procedure:
