I have the radio with all the bells and whistles, and SYNC. I can't get any mp3 player to work or any portable device to work. I do have the usb port and line in port right on the front of the radio. When I push the MEDIA button I do not have a "line in" choice on the left as it say it should in the book. Is there something I am missing???? Oh and this is a 2009 F-350


Thanks
Steve
