okay my i Mate Jam doesn't work properly with the BT system in my X5.

I can make calls fine, but don't seem to be able to answer calls (it hangs up when I hit the phone button on the dash or steering wheel), and doesn't transfer the phonebook.

Ive had a look here :
http://www.xoutpost.com/html.php?file=bmw_bt_phones.htm

and also on the other sites that are mentioned at the bottom of the page, and of course no-one lists the iMate (Ithink its called an o2 XDA mini in the UK?) as being compatable.


At the bottom of the page I mentioned above it indicates that for the phone to be compatable it needs:

(a) Bluetooth + (b) Handsfree profile => ability to make/receive calls

(c) Object Exchange => transfer of phone book from phone to car


Checking the specs on my phone, it has/does all this,... so why doesn't it work?

Is it different versions of Bluetooth? how can i figure what is missing, so I can fix it?
