i just did the 2 part non navi install; went well; going to watch the beginning of raw then to confirm 2.2 has been installed; is it hard to pop out the usb port?
i just called walt sweeney ford and they said this is in stock (GJ7Z-19A387-B); so i ordered this and when i asked about the front usb port he said to only connect the gray cable and not the black cable and the front usb should work fine; i changed my order over to that one and he processed it...
at my dealer and asked for the part; he told me it is on back order until mid feb of 17 and that the part number needed is 19A387; i also have a diagram that he printed out; thought i would report in
after a quick google search it appears to be the dual usb port
