I'm looking to add a navigation unit to my car. I don't want to have a single DIN heat unit on my dash because that takes away from the stock look. I was thinking about a double DIN unit once the metra kit is available but I'd much rather have the screen on the dash for ease of use. So I was thinking, is there any navigation units that have a touch screen separate? I was thinking about finding a dash piece in the junk yard and possibly moding it to a flip screen. I found the Pioneer 80DVD but I'm hopefully trying to find something better. I'd like navigation, mp3, DVD, and hopefully bluetooth.
