Activating anti-theft alarm

During initial operation of the radio and navigation unit (A2/56) it is necessary to activate the anti-theft alarm with the aid of the hand-held tester.

After activation has been accomplished, deactivation is no longer possible.

Only after activation is it necessary to enter a 5-digit code after interruption of the power supply. When entering the code observe:

After the code has been entered incorrectly three times the message "Wait" appears. The radio and navigation unit (A2/56) is then disabled for ten minutes. ↓
Following the next three incorrect entries operation is not possible for ten minutes again. ↓
Then after an additional 3 incorrect entries the unit is disabled for 1 hour in each case.

The waiting time expires only with the radio and navigation unit (A2/56) switched on.

Inserting and ejecting CD

CDs can be inserted and ejected (audio or navigation CD) in all operating states. After pressing the "eject button" a CD already inserted is ejected by a motor. If the CD is not removed within approx. 14 seconds, it is pulled back in automatically.

After inserting a CD it is necessary to push it a slight distance into the CD opening; it is then pulled in the rest of the way automatically.

When a navigation CD is inserted the menu for entering destination is activated automatically. However, this applies only when the system has previously requested that the navigation CD be inserted.

The eject button for the CD drive also functions when the radio and navigation unit (A2/56) is in the "code wait state". This means that a CD can be removed in spite of the request to enter the anti-theft code.
