1st post - and I ask an awkward question! 
Does anyone know the interfacing for the iPod nano screen and digitiser - and is it compatible with the DSI input on the Pi?
The reason I ask is I plan (I always 'plan', sometimes I even 'execute'), to build a Car computer with my Pi.
Not the usual 'run-of-the-mill' media centre, but a full replacement dashboard.
As I don't have OBD (or even an ECU) I will be needing a Gertboard for sensor inputs (Speedo, Revs, Fuel Temp) and Dash warning lights. The intention is to drive graphical representations of the existing analogue gauges, and warning lights could be replaced by text prompts. (More on that in later posts). 
Where the mini touch screen comes into play is for starting/stopping the car.
The idea is the provide a 'Start Button' graphic when the Pi detects an input from the RFID reader I have (logic state change) and then pressing the touchscreen starts the car, on detecting that the engine is running the graphic then changes to a 'Stop Button' graphic - and you can probably guess what happens when you touch that.
Basically, I want to use a pretty display instead of a really easy, cheap, already provided on the Gertboard as a buffered input, button!! - Sorry!! 
Any ideas? (Other than 'just use a damned button you fool')!!
