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.
Electronic Anti-Theft System
Radio navigation system RNS 510 is equipped with an electronic Comfort antitheft system which operates in conjunction with the instrument cluster.
After disconnecting the power supply, the radio navigation system is ready to be used 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 navigation system is reconnected in the same vehicle.
Reactivating a locked radio navigation system is only possible by entering correct code number for electronic antitheft system.
The anti-theft code is accessed by guided fault finding VAS 5051 or the guided fault finding VAS 5052; the radio card and the sticker on the radio unit have been discontinued.
To access the antitheft code the guided fault finding VAS 5051 or the guided fault finding VAS 5052 must be connected (network connection) and the user must provide a valid program user id to retrieve a radio code.
