Have wonderful 2011 135 M. Only let down is stock radio. No phone ? No blue tooth ? Steering wheel has phone button but phone option was not included on this car. I am wondering if BMW used same steering for all cars. Would appreciate suggestions on upgraded after market radios work with standard BMW wire harness.

Aftermarket units are always difficult or impossible to integrate with the factory system. Sorry, but you might be out of luck.

You could have an aftermarket unit installed, which you could get one with Bluetooth, and it would probably work fine. But, steering wheel buttons are another story.
