I've got a 2008 Grand Dodge Caravan with a MyGig 430 ren HDD that won't load songs from the USB port. Everything else seems to work. But when I plug in a cellphone or an MP3 player using the USB port, it can't find any songs. With the cellphone, it tells me it doesn't recognize the device. When I plug in an MP3 player, it says there are no songs or pictures to download (when I have both on the MP3 player). Has anyone else had this problem, or know of any solution?
