I installed the "B" phone cradle and the BMW BTUM blutooth module in my early '05 A8. In 5 seconds I had a hands free phone system for $500 using the onstar voice keys from the Audi owners manual. The steering wheel button and volume works perfect and the radio mutes. All fine. I have used a Nokia, and Samsung, and a Blackberry and all work great. One thing though, I read where I should get my phone book from the blackberry to display on the little screen between the tach and speedometer but it doesn't. Do I need to recode the system to recognize the phonebook using the VAGCOM? If so, how?
