It is necessary to calibrate the digital compass if:

• The compass directions are not correct,
• The letter "C" instead of a direction will appear or the display will be blank.
• A new Automatic Dimming Interior Rearview Mirror -Y7- is installed.

The digital compass may also need to be calibrated if:

• the vehicle battery was reconnected after being disconnected for an extended period,
• a new audio system or audio system component was installed.
