Everything worked great on my 650. I got my new 700P and everything seemed to work right. In fact it seemed to work better, the phone would turn its headset symbol on as son as it saw my connected device. The problem is that when I make a call it is connected, because when I hit the button on the headset/car kit it hangs up the call. It, however, never transfers the voice over to the headset/car kit. I have unsync'd/resync'd the devices, done soft resets etc....nothing seems to work? Any thoughts?
