I have paired my HTC-One with my new 2011 F10. It works very well when it works. However, sometimes it seems as if the contact with phone and car is only "half way":

What happens is I receive a call and I cannot answer with the button on the steering wheel - I have to answer by pressing down the Idrive-wheel. Then, I can only hear the caller in the phone itself (I suppose the speaker of the phone turns on...?). The caller, however, can hear me fine. If I ask the person to call me again then everything works as normal.

It seems to me this happens when the phone is in my jacket lying in the back seat - have to do some more testing.

Has someone else experienced this? Does the phone need to be close to the dashboard for working properly - i.e. in the front seat?
