Theft protection: Function

WARNING: This page is about a different car, the 2006 Saab 9-5. However, it is still accessible from the selected car via links, so may be relevant.

Theft protection is effected by "marrying" the head unit to the car. If such a "marriage" has not occurred, "LOCKED" will be displayed when attempting to activate the audio system.

The audio system checks at regular intervals that the theft protection information is correct (if "marriage" has occurred). This applies also if +30 is temporarily disconnected. If the information is not correct the display shows "LOCKED".

IMPORTANT: The audio system is "married/divorced" to/from the car with the diagnostic tool. Divorce can only be performed in the original vehicle, and with the correct ignition key in the ignition switch.
