You are correct that the iPad far exceeds the capabilities of head units. I use mine as an audio source, GPS, radar detector(Escort), weather radar, and of course I can check my email and messages along with numerous other apps. Once you put one of these in a vehicle, you won't want to be without it. Apple needs to build their own head unit. I believe it would sell like crazy. A good start would be to partner with an auto manufacturer like Tesla, or.....Porsche!
