For 1990-2009 cars only
Compass Operation
Press the COMP button to turn the compass on or off.
When the ignition and the compass feature are on, the compass displays the compass heading after a few seconds.
Compass Calibration
The compass may need to be calibrated if:
| • | If CAL is displayed while driving in the vehicle. |
| • | After approximately five seconds, the display does not show a compass heading (N for North, for example), there may be a strong magnetic field interfering with the compass. Interference can be caused by a magnetic antenna mount, magnetic note pad holder or a similar magnetic item. |
| • | The compass does not display the correct heading and the compass zone variance is set correctly. |
In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, press and hold the COMP button until CAL is displayed.
The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction.
Compass Variance
The mirror is set to zone eight. If you do not live in zone eight or drive out of the area, the compass variance needs to be changed to the appropriate zone.
To adjust for compass variance:
- Find your current location and variance zone number on the following zone map.
- Press and hold COMP until a zone number displays.
- Press COMP on the bottom of the mirror until the new zone number displays. After you stop pressing the button, the display shows a compass direction within a few seconds.
