No Idea, but did you try removing the stick and disconnecting the battery? trying to force a radio reset..
Maybe that helps. and also check the usb stick on a computer to see if the car radio added a playlist or any other file to the root of the usb stick. (Try this before disconnecting the battery)
Good luck
