My Headset working fine.. I was having a conversation, when suddenly no sound from the headset. The caller was still on my phone.. Luckily I was in a parking lot, dragged out the phone and could talk via the phnone, but not the headset, withthe caller. Ended the call, took off & the headset was working fine for spoken directions from GPS.. It was as though the bluetooth connection to the phone from the headset, via the GPS, just stopped, My phone is a Blackberry Storm 2 through Verizon.
