How do you know if it is working? I did the usb drive and it scrolls something on top of the screen for a second and then nothing. I drove around for a while and finally gave up .... no indication anything was updating.
You need a USB Drive with a LED status indicator. If the LED is flashing then you know it is being read and it is working. If it's not flashing then something went wrong. Once the upgrade is complete, it will tell you to remove the drive and restart the truck. Mine took about 20 minutes total to complete.
