Yes sorry for the delay I was away from home and was using someone else's computer. I still need assistance with this.
I have been given the code from the PT Cruiser Dealership when I provided all the seriel no etc. with them and paid for the privilege of them giving me the same no which is written on the radio. It does not work. All they have now suggested is that the code must have been changed at some point and I will need to take it to a place which can break the code or to get a new radio!
No It is a Chrysler PT Cruiser
