2018 2.0T. New car has Garmin 2017 navigation map release. I Followed instructions to update the map to the 2018 version via USB connection. Steps 1 and 2 worked fine. However, when I started step 3 and inserted the USB Thumb Drive to complete the update I continue to get an error that the system cannot find the update file. Has anyone followed the steps outlined in the Navigation Update instructions and had success? I am confident that the Garmin Express program (used in step 2) put the updated map file on the thumb drive.

I've had similar problems with my Harley Infotainment system. The USB drive has to be a quality unit I believe 8 gig or more and nothing else on it with the file at the root of the directory. Perhaps the Honda has similar restrictions.
