Coding A New or Remanufactured Radio

Heidelberg VI fixed coded radio, coding

The Heidelburg VI radio is assigned a fixed four digit security code from the factory. Unlike previous radios the security code cannot be changed.






The Heidelburg VI radio can be identified by white lettering on the face plate and separate knobs for fader, bass and treble control.

The radios are not coded at the factory. To activate the protection, the radio must be coded during the Pre-delivery Inspection.






The security code and serial number of the radio are printed on a removable sticker located in the trunk near the vehicle identification sticker.
