On Windows 11 I extracted part1 with WinRar, and of course it extracted part2 too. Then I ran CityNavigatorNorthAmericaNT2026.10Update.msi and instead of just installing into Program files it asked me for a folder, defaulting to the root of whatever drive I have with the largest free space. Garmin, that is sooo effing not how you do Windows installs.

So I made a C:\GPS folder and directed it there. It went through the install and when done the C:\GPS folder is empty. There's no highlight in the start menu for a new app, nor is there a new desktop shortcut.

Rerunning the msi file offers to remove it. But where is it so I can use it?!

Next thing, I have a Nuvi 1300 and it will only load from SD card, one map img. I named the US map gmapsupp.img and per instructions found all over, the canada and mexico file gmapsupp1.img but it ignores it.

Unlocked gmap folder extract and copy to C:\ProgramData\Garmin\Maps

Just copy the entire folder City_Navigator_North_America_NT_2026_20.gmap to C:\ProgramData\Garmin\Maps as written above ,then use Mapsource/Mapinstall.

nuvi 13xx,on a FAT 32 Formatted SD card create a folder Map.
Map\gmapsupp.img
Map\gmapsup1.img

If that does not work put Canada & Mexico on the device.
.System\gmapprom.img (CanMex) 1.12 GB
On SD card
Map\gmapsupp.img (US) 3.40 GB

I've just upgraded from my 2008 Nuvi 765tfm which used CN Maps which are now discontinued. I have gotten a Drive 66. Which files do I need for this device?

Unfortunately it is NOT able to use or be made to use Unlocked maps.
Your nuvi 765t uses NT maps ,for Europe the last version is 2025.10

I have looked into both the github map tools listed on this forum and some up to date open street map images elsewhere.
I have a few older Garmin 1490s models that did have lifetime maps rights when I last used them.
Is it possible with the non-Garmin map tools to carve out just a subset of the whole map for regions I might use these older GPS devices within, and have a smaller map size that could fit within the device's small amount of memory?

I think my more modern LMT devices now get full North America maps from the company/source named "here".
The map tools should let me have the latest map portable on an SD card to use if I take these older "expendable" GPS devices into areas where they might get damaged or lost.

Ideally I'd like to remove the several years old map data from the 1490's old systems for loading map updates and replace it with a small region copied out from the more up to date maps, and hopefully see faster performance and up to date information.

It seems that open street maps gives me more information about natural resources such as the location of streams but I am not sure it is giving me the same quality of information I see for roadways within the commercial maps.

Welcome to the forum,I moved your post to this thread covering the latest N.America maps
Firstly your nuvi 1490 can use the whole of N.America with the use of an SD card, and if it has Lifetime map updates Garmin Express will prompt you.

Check out this post above it gives you some options.
If you want to create a custom map set use Mapsource/MapInstall. There are a couple of custom maps sets in this thread that might help.
