So I have a 5.5" screen thats been sitting in my room for maybe 2 years now. It was installed in my truck when I bought it, and it worked, but I haven't used it since and I'm not planning on it. I want to trade it for one or two QUALITY sets of RCA's. I dont have any of the mounting hardware or anything else besides the screen. I guarantee it will work and that it is in good condition but I don't know about picture quality or whatever.
