Since cupcake, the stereo bluetooth has worked flawlessly. However, for the last couple of days it has had a short 1/2 second pause about every 20 seconds. I can't figure out what the problem is. Have tried rebooting phone, re-pairing the two, nothing works. It is paired to my Sony auto stereo in my truck. I don't have any other headset that I can try, but I don't think that would be the problem as it worked fine for 2 months. Any suggestions?
