It would be the same as a tablet that was left in the car. except it wouldn't have a battery to overheat, and it would be protected from direct sunlight by the dashboard. It would be built into the dash, so you'd still have to take it apart to remove the unit. I'm meaning to use the tablet architecture as the platform for a single module dashboard 'brain' and display. It already contains all the electronics to support gps, bluetooth, voice command, hands-free, cameras, system monitoring and diagnostics, music library, etc. Essentially I mean use the 'guts' of a tablet cause it's already designed and ready to go. No development needed, just some simple programming. No reinventing the wheel. And since it is generic architecture you COULD replace the unit with the 'guts' of an off the shelf unit, which is çheaper than a decent gps alone.
