Anti-Theft Coding, Deactivating Premium 7: Notes
The radio has a anti-theft protection, 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 radio code does not need to be entered again. The requirement is that the first activation of the anti-theft system follows and that the radio is reconnected in the same vehicle.
Notes regarding function
After first activation of the anti-theft system, an internal radio code is stored in radio and in instrument cluster. If radio voltage is now cut off for repair work, a data exchange is then performed between radio and instrument cluster after reconnecting the voltage supply.
During this, the internal radio code is compared to the one in the instrument cluster. If the radio code is identical, the instrument cluster recognizes that the radio connected belongs to that vehicle and the radio can be used immediately. The radio code does not need to be entered again.
If the radio is replaced, radio code must be entered.
Deactivating electronic anti-theft system, refer to Electronic Anti-Theft System, Deactivating .
Then, after the "S-contact" is switched on via the ignition lock, the comparison between instrument cluster and radio is started automatically.
The comparison lasts approximately 5 seconds. Do not connect any diagnostic devices during this time or have any diagnostic devises connected.
When the power supply is disconnected, the radio is ready for use in this vehicle once the power supply is connected. The radio code does not need to be entered again.
The anti-theft coding is activated and locks the radio as soon as:
- The radio is installed in a different vehicle.
- the instrument cluster is replaced.
The radio has been locked by the anti-theft protection. After switching on the radio "SAFE" and "1000" will appear in the display.
To cancel the lock, deactivate the anti-theft protection. Refer to Electronic Anti-Theft System, Deactivating .
