Forgive me for not reading through the whole thread. I searched but couldn't find anything.
I recently bought a 2011 E91. It has L7 and Bluetooth Audio.
Question: is it possible to improve the signal quality with factory BT?
I love being able to use the factory buttons to change songs and see music info on iDrive.
Most of the time the audio quality is good, however sometimes it has trouble connecting and randomly cuts in and out.
