Does anyone know of a workaround for a locked Delta radio? I purchased a used car with a bad battery, and the previous owner did not have the code. I have tried all 1's and all 0's no luck. I tried to find info in the archive and could not find. I am tring to avoid a rebuilt unit ! TIA Kevin kbaisley@earthlink.net P.S. I am still looking for wood grain for 89 200 !!!!
