Instrument Panel Cluster: Compass

The compass, which is integral to the radio, sends a signal to the Instrument Panel Cluster (IPC) to duplicate what is shown on the radio navigation screen. The radio Uconnect® touchscreen offers the customer two different options to select that involve the compass:

• Compass Variance 

  - Compass Variance is the difference between Magnetic North and Geographic North. To compensate for the differences the variance should be set for the zone where the vehicle is driven, per the zone map. Once properly set, the compass will automatically compensate for the differences, and provide the most accurate compass heading.

• Compass Calibration 

  - Press the "Calibration" button on the touchscreen to change this setting. This compass is self-calibrating, which eliminates the need to manually reset the compass. When the vehicle is new, the compass may appear erratic until it is calibrated. You may also calibrate the compass by pressing the "ON" button on the touchscreen and completing one or more 360-degree turns (in an area free from large metal or metallic objects). The compass will now function normally.

If the compass is not reading properly or has lost its calibration, perform the following steps:

1. If the compass is no longer reading properly, perform the Compass Calibration procedure located in the radio options menu and then recheck the compass display.
2. If the compass is still not reading properly, disconnect the radio and then reconnect it. Several ignition cycles may need to be performed before the compass will read properly.
