Radio: Activate anti-theft coding by entering security code

WARNING: This page is about a different variant/trim than selected.

Radio units are shipped with a fixed code. Fixed code means that every radio unit with anti-theft coding has been programmed with its own code. This code is not active from the factory. To increase anti-theft protection, there is no longer a radio card in the radio and navigation system owners manual. The entry of the radio code is no longer described in the owners manual.

The Anti-theft coding on a unit that is ready to play is activated by entering the fixed code. 

On chorus II+, concert II+ and symphony II+ radio systems, enter the radio code as follows

If the radio code is entered incorrectly two times and "Code Safe 2" appeared in the display, use the following procedure

Leave radio switched on approx. 60 minutes. After 60 min., "Code Safe / Code 1000" appears in the display and the radio is switched off

Enter radio code again.

On navigation system BNS 5.0, enter radio code as follows 

NOTE:
  • Please inform the customer that he can only learn the anti-theft radio code from the service advisor
  • That way, thieves really cannot use the radio!
