I just installed the BMW 84 10 6 987 546 ULF module in a 2003 X5, and it works GREAT.

Biggest changes are faster bluetooth connection in pairing and phone connection, Larger phonebook storage, plus faster. Better handsfree voice quality and faster loading of phonebook.

I have only been using the system one day and have not found any more voice commands yet.
