Not at all certain, actually. But if my faceplate gets lost or stolen, I can apparently buy a new one from Alpine. (or if someone steals my deck and not the faceplate, THEY can call to get a new one) So, I'm guessing they are interchangable. And if I buy one and it doesn't work out, I can just resell it. The only other option is to call Alpine and check with them, which I should do. Thanks for reminding me.
