I have a Pioneer DEH-3400 head unit, but it seems some lowlife decided that I really didn't need the faceplate and stole it from my car. Does anyone know of a site that will tell me which faceplates are interchangeable with this model before I buy another one?

 

I found a place online that sells them but I didnt see one for your model #, they range from about 60-300, depending on the unit, if I were you id just buy a need deck, you can install it yourself since your just replacing it, sorry to hear that bro, some people are just so pathetic....

 

Nevermind found it, here ya go.... its $75, or you can get a new deck, Pioneer DEH-3400 face plate
