BMW X6 2010 Sound issue
 The sound system has started to going off in my car since last 2 months (in the beginning was intermittent but now a day happens so often). I bought my X6 in January and up to ~June I didn't have sound problem. But then later sound started going off (no sound for radio/cd, Reverse-alert, SOS, etc). Sometime restarting the Engine was helpful but not always. BMW Service told me because I had setup the bluetooth with blackberry which has an old version. But even after deleting the blackberry from the phone list and keeping the phone off when in my car I saw sound going off again. I am putting for my car at BMW for second time. I hope they will be able to fix it. I paid $87,000 for this car!
