This is all fascinating stuff. I myself don't have a DVD/TV function, but my dad has a DVD in his X5 and S-class - would be interesting to 'chip' it for them so my mum can watch movies on the fly.
A serious question though: does messing with the software invalidate the warranty or is this something that needs to be declared to the insurance company as some kind of 'mod'?
I dread to think that something goes wrong with the car or there's an accident and either/both of them decide they're not going to do anything under cover as we've messed around with the software...
