Does the USB drive recognize music on the thumb drive? FWIW, my glovebox USB was dead when I tried to do my last update and required service at the dealer to get it working again. There was at least one other member with a similar issue. After they dealer replaced it the update was easy.
If you can load music, then it may be the drive or the NAV files. If nothing loads, then you may want to check the USB interface.
