Chaps,
Resurrecting an old thread ... I have just called Midas Components (there was a link earlier on this thread to a form where you could enter LCD screen specifications) to ask about custom made screens. The person there was very helpful, but apparently custom-made LCD screens need to be ordered in minimum quantities of around 10,000, whereupon they cost about £2 each for the size we want. So, yes, that's an outlay of £20,000.
The guy also explained that the screen is almost certainly a part made specially for the car, and therefore won't be available off-the-shelf. That, combined with the total lack of any identification marks, kind of scuppers any idea of cheaply replacing the screen.
So, sorry. Drawn a blank again. Anyone else got any good ideas?
Oli.
