City Navigator North America NT2026.3

Anyone try loading NT2026.3 into Windows 11?

Just got a new computer last week (went from Windows 10 to 11). Hooked up my Zumo390, and Garmin Express says there's a new map update available. After the update was complete into the GPS, I then downloaded it into the computer.

When I went to Basecamp it showed "Map Detail Locked" in the lower right hand window of the Basecamp map (under the distance scale). I'm unable to see any of the small roads, only the main roads. When i look at the Map Product Manager. it shows that it is "Locked".

Garmin has opened a case file on this. They had me completely uninstall Express and Basecamp, but still have the same results.

Took the computer to Geek Squad at Best Buy, and they can't figure it out either.

The only way I can see the map details is if I connect my buddy's Zumo 396 that still has the older NT2026.2 map loaded in it.

I use Basecamp to create remote backroad routes, then download those routes into my GPS and lead a group of my motorcycle friends on rides. Trying to create a route in the GPS takes forever.

We're questioning whether the NT2026.3 is compatible with Windows 11.

Anyone else have this trouble with the NT2026.3 and windows 11?

The map is compatible with Windows 11. Does this map work on your zumo 390? In that case you can copy the map certificate from your device to your PC.

The certificate has the extension .gma and is problably called "gmapprom.gma". You can find it in the folder .System on the zumo (or maybe .System\Map). The .System folder is hidden by default, so set Windows Explorer to show hidden files.

The right file has a timestamp of the moment you updated your map. Copy it to your computer and use the Map Product Manager to import that file.

Thanks for the help. To answer your question, the map details did not work with the gps plugged into the computer. Garmin said that when the Geek Squad moved everything from my old computer to the new one that the files must have gotten corrupted. They had me completely delete the Garmin folder, restart the computer and re-%download Garmin Express. This worked, as I am able to now see the map details. The Geek Squad also screwed up all the Routes I had saved under my Internal Storage, but I guess recreating the 100 or so routes will give me something to do on those rainy days.

It is working on my Win11 24H2 Pro so compatibility is not an issue.

Yes, I had the same symptoms that you report which I was able to resolve. I hope this helps you...

I run Win11 credentialed as a local account with standard user privileges. The map installer triggers User Account Control prompting for administrator credentials. What then happens is the map gets installed, but only unlocked for that admin user. My solution was to:

uninstall the map
log out
log in as administrator
elevate my user privileges to administrator
log out
log in as me
install the map
log out
log in as administrator
set my user privileges back to standard
log out
log in as me
Run Basecamp. Map is now unlocked.
