That's a good point, in fact my COMBOX did indeed have Bluetooth and it only needed to be turned on. The issue however was less about programming and more about finding the proper wire harness to connect the Bluetooth antenna and the microphone.
So after 16 months with this car and trying a bunch of options to get a decent Bluetooth option, I am happy to say I have a solution that is stock BMW and a dealer would never identify that anything is modified.
Anyone interested in buying a slightly used - totally functional but not perfect mObridge device? Mine is on eBay right now:

If you guys want to know more about how I was able to get this to work, let me know...
Cheers!
