Head Unit not reading USB

[GTS]

So I have a deck that reads USB. I use a USB key to play music off the deck. I've been using this deck for almost 2 years with no problems. Recently, the deck has stopped reading the USB. I mean...it's not even detecting it.

I've already looked up the compatible formats and ensured my music is in the correct format. I've tried different USB keys and still have the same problem.

This is a long shot - but does anyone have suggestions?

Have you tried resetting it? Other than that I think it might be done.

What deck is it? From time to time i'll accidentally put a corrupt file on my usb then it causes my unit to not read it anymore until i power cycle it by simply unplugging the unit for a minute or so then it works fine. Could have been the same issue with yours.
