nope.. not touch screen.
... thank god.
... my brother had a touch screen in his car... pain in the ass... especially if your car is lowered and you have a stiff suspension... changing tracks and hit a small bump and you give the thing a hard poke.. think you're going to break the hinges on the thing. :/
Honestly.. although I'm typically not a fan of Sony... it's an awesome headunit, loaded with features, and turns everyone's heads... can't complain with 7.5" TFT either.
