The Bluetooth will just turn itself off, no real pattern. Sometimes 3 times in 3 minutes, sometimes works great for two hours. Mostly it turns off while I'm listening to tunes on my Cardo S-2 Headphones, but it does turn off at other times - like when I'm not even using the phone. It has happened at a variety of places - home,work,walking down the street,restaurants, etc... - so I don't know what kind of interference would be in all those places.

Any ideas, thanks in advance!
