    Dealer was no help, they referred me to a GM tech updated about not all usb will work. They also told me the updates can’t be rolled back.

    I having issues using usb drives. I purchased the first shipment to the dealers. Had issues with the display between the gauges, locking up and turned blank. After the software updates my usb drive does not work anymore. I was using a 32 gig original after the first update to then the display stopped blanking out but the usb stopped reading in either port. The dealers showed me a tech bulitin that stated not all usb will not work, but could not tell me what would. I went down to a 1 gig and it worked until the last update now nothing’s works. Any ideas
