I did go to Garmin's site and updated with Garmin Express. It only took about 5 minutes to update which didn't seem right. It only did a software update and didn't seem to do any maps. When I checked the installed map it still showed City Navigator North America NT 2015. It's now showing the 2017 version. I had originally got a message on the unit saying that the 2015 version was a year old. I had also got this message about 6 months ago and updated then also. 2017 was to be installed with Garmin Mapinstall and it told me that there wasn't enough room so I had to go about it a different way.
