GMC Envoy XUV Automobile User Manual


 
Compass Display
O
(On/Off): Press this button to turn the compass on
or off. The compass display, can show a maximum
of two characters. For example, NE is displayed
for north-east.
When the ignition and the compass/temperature feature
are on, character boxes will appear for about two
seconds. After two seconds, the mirror will display the
direction the vehicle is facing.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass direction, (N for North,
for example), there may be a strong magnetic field
interfering with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item. If the
letter C should ever appear in the compass window,
the compass may need calibration.
Press and hold the on/off button for nine seconds to
activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display shows
a direction.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
The mirror is set to zone eight upon leaving the
factory. It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain conditions, such as during a
long-distance, cross-country trip, it will be necessary
to adjust for compass variance. If not adjusted to
account for compass variance, the compass could
give false readings.
