I'm driving a 2006 X3 3.0i and have it paired with my 8900. Took a bit of experimentation, but in the end it paired fine. Once paired, I find that the 8900 and the X3 connect very quickly when the phone is in range and car is on, disconnecting immediately when the car is shut off.
BMW's bluetooth implementation has been awkward and glitchy for a while now. Read some of the BMW forums (e.g., bimmerfest or bimmerforums) to get a sense of this. BMW service folks apparently also seem to generally take the view that if your bt phone isn't on the "approved list", you may wind up "damaging" the BMW's bluetooth unit -- resulting in an out of warranty repair charge in the neighborhood of $700. As far as I can tell, though, this is bunk. Turns out that when a car is brought in with non-responsive bluetooth, the first thing they do is unhook the power to the unit and to a cold start -- and this "fixes" most issues. Well... it's not that hard to do the same thing yourself, depending on where your BT unit is located in your BMW.
In the X3, I can get to the ULF from the back hatch. Standing behind the X3 with the hatch open, I can see a removable panel on the left side of the interior, just inside the hatch door. Once that pops out, the view is similar to this:
...and the ULF is the silver box at the bottom. The red arrow points to the power connector. Apparently, you can simply unlock and remove the connector, wait 30 seconds and replace it, and this "fixes" a myriad of BT issues that BMW's suffer. When my BMW BT becomes unresponsive, this is an instant fix for me. On the other hand, if this continues to be necessary, it may be worth having BMW replace the unit (assuming you're still under warranty).

Worst case, there are some good after-market alternatives available for BMW's...
