You can buy just the faceplate, but it is almost as much as a new deck would cost, so its not really worth it unless you have a really highend deck. And as for the face plates only working with the radio it came with, pioneer, sony, and others, as long as its the same model the face plate is interchangable. ex. pioneer 7700 i can take my faceplate of my deck and stick it on my friends 7700 and it works just fine.
