Haha... thanks for that ground breaking info Rhyda###
Just an idea. They have those "control your phone over vnc" apps. If you hooked up your touch HID to a netbook stuffed under the seat, you could then vnc them to the phone. That would be a huge deal and require a lot of soldering though. And I'm thinking every time you got in the car you would have to spend 20 minutes hooking it all up.
My suggestion would be to sell your touch screen audio system in your car, not put such emphasis on the user experience in a tool that is designed to get you from A to B, and post similar dreams you are having in the right forum sections. I mean, girls aren't impressed with xbox 360s modified with blue LEDs and probably not with touch screen cd players.
(this is all meant as a joke...)
