Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Anti-Theft Coding
The radio has a comfort anti-theft protection, which operates with the instrument cluster.
After disconnecting the radio power supply, the radio is ready for use again once the power supply is connected. The anti-theft code does not need to be entered again. The requirement is that the first activation of the electronic anti-theft system follows and that the radio is reconnected in the same vehicle.
The anti-theft code is transmitted via the Vehicle Diagnostic Tester. The radio card and the label on the radio that were used in the past are no longer used.
To access the anti-theft code the Vehicle Diagnostic Tester must be "online", connected (network connection) and the user must provide a valid program user id to retrieve a radio code.
