If you're running a Nav V then why mount the iPhone? If your not running a Nav V, take the mounting off and mount the phone in its place. There's plenty of mounts (google). I get that the phone has GPS, but unless you have conductive gloves and a steady hand, you can't really use it. Get a bluetooth headset to take calls etc either from the phone or through the Nav - Cardo SHO-1 is ace.
