From my other link, I don’t think that the touch screen is an optional purchase. I don’t think that they’re selling any entertainment computer to have a screen on. It says that they come standard with a smartphone mounting point or optionally with a tablet mounting point. But the car computer is bring-your-own, and not built into the car. Which…is what I’ve wanted, because computers age out a lot more quickly than cars do.

I assume that there’ll be an OBD-II slot that one can hook up to to feed data about the car to the phone/tablet. There’s software that can make use of that. Dunno if there’s any other data typically exposed to car computers other than what that provides.
