Hi All, Contacted TWR garage (they provided the car originally and maintained it up to 150K miles.). They were very co-operative and phoned me within 5 minutes with a code. Regrettably the radio did not accept it; I assume that it was changed fairly recently. Local advice was that my only choice now is to remove the radio, observe the serial numbers and try a Jaguar agent again. Is this good advice and are there any other options? J
