Looking to upgrade my current stock head unit with a double din dvd unit. Can get one of these for 200 new from a guy I know. As for what I want in the head unit, good sound quality with the ability to upgrade interior speakers in the future and still sound good. Play dvds obviously. Bluetooth and nav is not required right now but can add on later. This head unit pretty much covers all that except it's not a full 7" screen. Any opinions. If this doesn't pan out right I'll just be looking for a good quality single din cd player I guess.
