DIGITAL RADIO RECEIVER

The digital radio receiver utilizes class 2 serial data to determine if it is in the appropriate vehicle. Each time the digital radio receiver receives the "run"power mode message, it compares the VIN information received from a module which supplies VIN information on the class 2 serial data circuit. If a mis-match occurs, the radio display will indicate to the user the digital radio receiver is locked. The digital radio receiver cannot be unlocked, it must be replaced. The two scenarios able to cause this condition are:
1. A digital radio receiver is installed from another vehicle
2. A module which supplies VIN information is replaced and not properly setup with the correct VIN information for that vehicle.

The radio controls communicate with the digital radio receiver via the class 2 communication circuit. The digital radio receiver sends low level audio signals to the audio amplifier.
