Default RES to RBZ swap

Hey all, I know this has been beat to death but i can't seem to find a firm answer. I just purchased an RBZ high speed bus (4678) from ebay. My question is once I install it into my 2012 Ram do I need to go to the dealer and have the PCM flashed for the thing to work? I don't have a back up camera. If anyone can help it would be greatly appreciated. I just don't want to freak out once I get it installed. Thanks!!
