No joy, I'm afraid. They say they can only get the code for the radio when it is installed in the car and they then contact Germany. I'm afraid I can't go back and uninstall our Concert CD player to do this as the CanBus emulator would have to come out as well.
I tried the original dealer too - they don't have records going back to 2001.
You are welcome to have the radio cassette for just the cost of sending it to you (£8) if you think you can get the code for it.
Cheers, Graeme
