My comments above were based on contibutions over at the E60 board.

Essentially, I believe it can't be that much different to the current 5-series (but willing to be corrected). Some guys over there have successfully had it retrofitted.

(there are more)

However what is clear from this is that you get different answers from different dealers - and it is not a black and white answer (even though it should be). Might be worth a call to Sytners - they seem to be the dealer most people get it done by. It is a UK option - I know of other people that have had it fitted as a factory option.
