CD Changer (CDC): Security

The radio headsets are no longer protected by a manually entered security code system. If a valid K-bus message isn't received, the radio will remain inoperative ('Disabled' status). Normal radio operation will commence once the radio has received a valid K-bus message. Each time the radio power supply is disconnected and reconnected a K-bus message is sent to the radio and if OK, the radio operation recommences. This security function also applies to the CD Autochanger when equipped.
