Factors Affecting Compass Accuracy
Magnetic mounted devices (antennas, racks, etc.)
should not be located on the front third of the
vehicle roof. Placement of these devices near the
compass will cause the compass to be inaccurate. If
these devices are used, for improved accuracy,
recalibrate the compass with the device(s) installed.
Driving near power lines or large iron or steel
structures can temporarily change the compass
heading. Demagnetize the vehicle and recalibrate
the compass if it remains inaccurate after driving
near such objects.
Compass Adjustments
Press and hold the COMPASS control, then press
the RESET control. Next, release both controls. The
display will show the “Compass Menu” (Figure 1).
The letters on the left side of the arrows indicate
the control to press to perform the adjustment
indicated on the right side of the arrows, as shown
in Figure 1.
