Compass Operation - Chevrolet 2005 Equinox Owner's Manual

Temperature Display
The temperature can be displayed by pressing the
TEMP button. Pressing the TEMP button once briefly,
will toggle the temperature reading on and off. To
alternate the temperature reading between Fahrenheit
and Celsius, press and hold the TEMP button for
approximately four seconds until the display blinks °F
and °C. Press and release the TEMP button to
toggle between the Fahrenheit and Celsius readings.
After about four seconds of inactivity, the display
will stop blinking and display the last selection made.
If an abnormal reading is displayed for an extended
period of time, consult your dealer. Under certain
circumstances, a delay in updating the temperature
is normal.

Compass Operation

Press the COMP button to turn the compass on or off.
When the ignition and the compass feature are on,
the compass will show two display boxes for
approximately two seconds, then the mirror will display
the compass heading.
Compass Variance
Compass variance is the difference between earth's
magnetic north and true geographic north. If not
adjusted to account for compass variance, the mirror's
compass could give false readings. The mirror is
set in 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 circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance.
