Well my car had an Alpine CDE121 deck and faceplate in it and well someone stole just the faceplate. And I recently bought a Alpine CDE 122 and tried just the faceplate on the old deck and well it didn't work. Is there some difference between the 2? They are both a single DIN. I did buy the CDE122 used and am hoping that it isn't broke Hahah. I do have the new deck as well just kind of lazy and don't want to install it if I don't have to.
