Anti-Theft Code

General Information

The radio is equipped with convenience anti-theft protection, which operates in conjunction with the instrument cluster.

After disconnecting the power supply, the radio can be used again after connecting the power supply. The anti-theft code does not need to be entered again. The requirement is that the anti-theft coding must be activated for the first time and that the radio is reconnected in the same vehicle.

Anti-Theft Code, Deactivating

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


  • The code number for the anti-theft system is attached to the radio card next to the serial number. Refer to the Owner's Manual.
  • For reasons of safety, do not leave the radio card in the vehicle. Obtain the code number from the customer, if necessary.
  • If a radio is being replaced, then use the number code of the replacement radio.
  • Inform the customer the radio code has been changed.
  • Obtain code number for the unit.
  • Switch on radio.

"SAFE" automatically appears and then "1000". No operating of buttons is required for this.

Position for code number to be set is indicated in display near four multi-function buttons with "_X_".

  • Enter the radio code found on the radio card in the correct sequence using the four multifunction buttons. Press respective buttons in succession until the correct characters are shown in center of display.
  • Then, press multi-function button near word "ENTER". Unit is ready for operation again and switches to last operating state.


If the wrong code number was entered when overriding the electronic lock, first "SAFE" blinks in the display and "1000" appears again. You can now repeat the entire procedure one more time. The number of tries is shown in the display. If you enter the wrong code again, the unit is locked for about one hour, that is, it cannot be operated. This lock is indicated by the word "SAFE" appearing continuously in the display. After one hour has passed in which the unit and the ignition must be switched on, the number of attempts disappears and the electronic lock can be deactivated again as described above. The cycle "two attempts, locked for one hour" still applies.
