Radio Code & PROTECT Repair Service

Porsche CDR23
Becker BE 6612

As originally fitted to :

Porsche


If you are trying to fit this radio to a different vehicle, then you may find yourself with the Error message of "PROTECT". This stereo is electronically paired, or "Married" to the engine management system of the vehicle it came out of using very sophisticated MOST-BUS system technology.

When it is first powered up, it will communicate with the vehicle, and a message of "PORSCHE" will appear on the display whilst this process is in operation. If communication has been successfull, it will then operate in the normal way.

However, if removed and refitted into a different vehicle other than the original one, it will not recognise the encrypted MOST-BUS identification of the new car, and will instead display an error message of "PROTECT" after around 30 seconds.

This Radio cannot therefore be transferred from one car to another, unless it has first been reset back into its original "Delivery Mode" with the internal MOST-BUS data memory reprogrammed for use with the new vehicle.

Porsche Dealers may tell you that this stereo cannot be reprogrammed to go into another vehicle, but then thats what they said about other models, before we managed to reset the MOST-BUS PROTECT system !!

We can reset the PROTECT Error message for this radio, allowing it to be used in a different vehicle, but you will need to send the unit to our workshop for this work to be carried out. Approx turnaround time is 48 hours from receipt to dispatch.

Removal of the radio is fairly straightforward. The removal tools are inserted into the two flat horizontal slots at the lower edge of the fascia until a click is felt. The radio can then be withdrawn and the leads unplugged.

Common Fault Complaint: NO AUDIO

We get a number of phone calls from people who have retro fitted this model and then claim that there is no audio coming out. Unlike its twin sister model, the BE6611 CDR23, this model does not have a built in audio amplifier, and was designed to run an external audio amplifier located elsewhere in the car.
