My Motorola HF850 worked just fine with my Verizon 650, but the 700P does not want to stay paired. Pairs up immediately when you start the car, but as soon as the 700P screen turns off, it loses pairing and has to connect again. Never fails to re-connect, but having the screen light up again every few minutes is a bit distracting. particularly at night. I changed the settings from Hidden to Visible, but the problem remains.
