The thumb drive Nav update came in the mail. In order to allow the thumb drive to upload into the truck, you need to activate it. In order to do that you need to fill out a form on a website with several lines of numbers. Then they will send you a activation code to your email. Big time snag as the AI robots did not like my email address, that I had for almost 20yrs. So I was dead in the water . I called a help line, 1886 462 8837, and after getting through to a real person, she talked me through the update. Dictating several large codes over the phone was very easily gotten wrong, so there was several attempts. Took about an hour of idling the truck to get the update done. The help person was great , the experience really sucked.
