I think I pretty much already know the answer to this one, but thought Id ask just incase!
In my car I have an Alpine headunit with 7" touchscreen.
Obviously my initial thoughts were to use a Pi with it for sat nav/music etc, but if that was the case I would need to control it all.
Does anyone know if it would be possible to use the touchscreen aspect of the screen to control the software
Im guessing not as there would be no way to interface it with the Pi
Im not sure if I want to remove the stereo in place of a touchscreen that would work as I also have ipod connectivity (not such a problem as I could use a external drive with the Pi) but also have digital freeview tv which would not work with the Pi either
