My husband and I have an 09 535xi and 328i and had been experiencing endless Bluetooth/iDrive issues for months so we decided to upgrade to new Motorola W755 cell phones last week. It was a snap to pair the phones with our vehicles and so far we've not experienced any issues. The Verizon rep said the new phones have better, more stable Bluetooth software. We'll see. Nothing is more annoying than having to dig through stuff to answer the phone because the Bluetooth isn't working.

Happy motoring...
