If your radio has the wording "anti theft" on the front lower panel you need a 4 digit code before it works. I had the same deal with a radio I bought for my express. My RBZ came from a 2012 Chrysler and the seller provided me with the code. Apparently this code is needed anytime the radio is installed in a vehicle with a different VIN. After it is entered it doesn't ask for the code again. I think this anti theft feature was new for the 2012 radios. Good luck with your setup.
