Thread necro, but I have the F700BT and I can connect my Droid Razr just fine via USB, just set the phone to mass storage device in the usb options when you connect it to the HU. I can go through all the music on my phone and play it. Video's don't seem to work (yet), but music works just fine via USB for what its worth. I can use the radio controls to change songs, so its better than using a headphone cord to the aux port.
