The RNS 315 has anti-theft coding, 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 anti-theft code does not need to be entered again. The anti-theft coding must be activated for the first time and the radio navigation system must be connected in the same vehicle.

Reactivating a locked radio/navigation system is only possible by entering correct radio code number for anti-theft protection.

Use the (VAS5051B) to get the anti-theft code. The radio card and the label on the radio that were used in the past are no longer used.

• The (VAS5051B) must be online (network connection) to access the anti-theft code. The user must have proper authorization to access the anti-theft code.
