I am mirroring off a thread on E53, which I benefit greatly by reading through them, thought to start one on the E70 plate forum. ( I did a search and there isn't one)

Anyhoo...

I may have seen lots of people think the Bluetooth streaming music is impossible, after configuring on the idrive, which you can go

cd multimedia, external device, the phone your blue tooth hooked up, takes a while to let the car configure. But, it will work!

Make sure the Bluetooth audio is enable.

Let me know if anyone needs help
