Well I hate to tell you this but if you read my post near the start of this thread I said it did not work and bearing in mind I have had a lot of sucsess with getting lots of various makes and models working with the BMW bluetooth. I think you need to know who to trust when you get info of the net. I have been a member of this forum for some time and post pretty regular,Where this guy who said he had the 8800 working with his M5 could have been a 15 year old boy who thought the M5 was a cool car and the 8800 was a great phone so they are going to work.

I am sorry that this has cost you money, but at least you have a phone that works now.
