I got my car from a dealer and the stock radio is locked due to him putting in a new battery. I have the code to unlock it but in the code their is two zero's in it and I dont know which button is the zero. Any help would be greatly appreciated.
I think you scroll up with seek +/- or tune then hit another button for 'next'.
Are you sure you don't have the "pre-code" that has to be descrambled on the ac delco 800 hotline?
