Dan, I remember that - it was a Golf owner that reviewed it and said it was a POS.
As for the Colour DIS (Audi speak for the MFD - it stands for Driver Information System) the costs are extremely prohibitive in retrofitting this to an Audi. Apparantly it is a whole new instrument cluster, so I doubt it would be a case of swapping the red screen for the colour one... if that was what you were thinking?!
There are a number of slight differences, eg Audi's have a seperate clock in the speedo (with date!) so there is no clock on the top line of the MDF / DIS, which is great actually as the space where the clock is on the Leon is reserved for warnings only.
The red DIS also allows you to configure what is displayed by the trip computers - on the Leon you couldn't do this. There is also a seperate button for the Speed Warning (can't set it in the DIS) and there are actually 2 types of speed warning... One you can set through the MFD and one you can't.
Last but not least, radio stations are displayed on the DIS as well as MP3 track names...
So my guess is that the software has significant differences and therefore I don't think you could change it.
One other thing, if you are thinking of buying a 2nd hand cluster - they can only be recoded to a different car within the first 100,000km. Something to do with the immobiliser. And even then VAG-Com can't do it - you need a
dealer. From what I can gather.
PS Those pics are from the new A4 - even less compatible than the old A4... I would look to the A3 if you are interested in this. And I don't think colour DIS is available for the old A3...
