I like to have head units that run android, so I can load up Google maps with traffic etc, but as it's only a single DIN slot I've gone for one with a 7" flip out screen. It has 2 video inputs (one for reverse camera and one for action/accident recorder) and video output to other screens, plays DVDs (for the kids in the rear seats, although I'll probably get a roof mount DVD for them), GPS for Navi/offroad tracks and Bluetooth for handsfree phone. Only seemed to be available from Hong Kong ebay, but should be here in a week or so. (yeah, I haven't got the Disco yet!).
