'10 Outlander GT Stock USB not working
 

I have a 2010 Outlander GT with the stock USB port. For about a year I was able to have my ipod linked through it with no issues. Than one day I go to listen to the ipod (which I have made no changes to) and it only says "reading" on the nav screen and never loads anything. I've tried using my kids ipod and different cables to troubleshoot and still have the same result. Everything else seems to be working correctly, just the USB option. Please help!
