My ultimate plans are to obtain a pre-98 (or Mondeo... if it fits) console and put a 7" touch screen in front of the shifter.
Eventually will build a carputer in there with it's outputs going to my Pioneer HU's AUX input. That way I keep a "normal" audio system in the car for when I don't wanna run the computer.
...Or I'll probly cheap out and buy an Ipod+connector and jack it into my CD player...
