Yeah, I thought it was a bit of a long shot. Damn. Oh well, I'm going to end up replacing the screen anyway with an TFT screen driven by the PC, so it doesn't matter quite so much now.

Just wondered if anyone had been able to get their hands on, what in hindsight would probably be confidential BMW technical information!

Suppose you could reverse engineer it though if you had the right equipment, but then its down to time vs benefits really. As you say, its not much of a point with BMWs as the colour screen replaces it, its only the MG & Rovers that have the screen in a different location and additional to the Sat Nav screen.
