Compass
Compass Operation
Press O or AUTO 3 , depending on the vehicle,
to turn the compass on or off.
When the ignition and the compass feature are on, after
a few seconds, the mirror will display the compass
heading. The compass automatically calibrates as the
vehicle is driven.
Compass Calibration
If after a few seconds, the display does not show the
correct direction, (for example, N for North), there
may be a strong magnetic ?eld interfering with the
compass. Interference can be caused by a magnetic
antenna mount, magnetic note pad holder or a
similar magnetic item.
