Who said it was an infotainment device? That's as short sighted as calling an iPhone "just a phone."
The point is, if you make the full data stream and some controls available, people will step up with interesting ideas.
Beyond nav, music and phone calls, why not have these very tasks integrate with the hardware as you would like?
•Control the radio with your device.
•Displaly extra info on what's playing on the radio
•Phone calls through audio system (obviously)
But why stop with these?
•Change mirror and seat settings (cars that do this usually only remember two people.)
•Why not read your vehicle's trouble codes with your "infotainment device"?
•Why not choose a custom display of engine performance or instantaneous gas milage?
•I'm sure people who love to hack the subtleties of engine performance would love to use an iPhone or iPad to record data and make adjustments (this gets into the safety issue, but people can do with their car as they please.) NASCAR could sell an app to their fans.
•How about an app that gives feedback on driving performance in terms of safety, economy, shifting choices, or whatever?
"If you build it, they will come." Until it's built though, nobody knows what people will want to do with it.
