Radio Unit With Electronic Comfort Antitheft System

Electronic Antitheft System

Radio unit is equipped with an electronic Comfort antitheft system which operates in conjunction with the instrument cluster.

After disconnecting the radio power supply, the radio is ready for use again once the power supply is connected. The antitheft code does not need to be entered again. The requirement is that the first activation of the electronic antitheft system follows and that the radio is reconnected in the same vehicle.

The antitheft code is transmitted via the vehicle diagnosis, testing and information system (VAS 5051) or the vehicle diagnosis and service system (VAS 5052). The radio card and the label on the radio that were used in the past are no longer used.

• To access the antitheft code the Guided Fault-Finding (VAS 5051) or the Guided Fault-Finding (VAS 5052) "online" must be connected (network connection) and the user must provide a valid program user id to retrieve a radio code.
