I don't understand what you mean by Pro file. These files have been loaded in the map update. Why are they strange?

Most probably left overs of the 2012 NT preprogrammed maps you had causing a conflict. The G2S folder is just taking up space now. Compare your device files & folders with the one I shared [Only registered and activated users can see links. ] now contains .system folder

Hello Garman, now I understand you. You think there is a conflict between the 3D map files.
I explain to you:

Voice commands do not work with these maps either, I have carried out the test with all the ASR files that I had from the web download, and I have also tested it without these, only leaving the original ASR files.
Tomorrow I will try to test if the crossover view (JVC) works well.

When the nüvi became a 37xx, I copied some files I found on a website and these corresponded to City Navigator 2025.10 Western Europe. Subsequently, I connected the nüvi to Garmin Express and it was from this moment that Garmin Express offered me a complete City Navigator Europe update. So, I updated the map but I didn't do it with the nüvi connected (I was afraid it would get messed up again), but with a USB simulating it as if it were the nüvi. When the installation of City Navigator Europe 2025.10 was finished, I copied all the files to the nüvi and the maps in the photo above appeared on (my maps).


Once the transformation of the nüvi to 34xx was completed and after uninstalling, deleting, deleting any Garmin folder or file from Windows 10, including deleting the Windows Registry, I deleted the GarminDevice.xml file from the nüvi 34xx, and installed the Garmin Express, I connected the nüvi 34xx and that was when Garmin Express offered me the 5 updates that I showed in post no. #33.

When I updated the map, as Neil told me (with the nüvi connected) that was when all the system folders, voice, JVC, SID, and the maps that were installed were installed, I think they are correct. These are my maps shown now.

Now, in the 3D map, the Pro coding is no longer shown. It is possible that in the map update like nüvi 37xx, a somewhat corrupt installation was made, but I get the feeling that now, like nüvi 34xx, the map installation is fine.

This week, I will review my folders and compare them with those in the file that you have provided me, my idea is to delete the files that the system used when it was nüvi 37xx and leave only the ones it needs like nüvi 34xx, since, as you say, they are files that only take up space and can even generate some type of conflict. I will keep you informed.

By the way, I still don't see the .system folder.


Thanks for your help Garman, a hug.

As it's been shown that your device's region 41 doesn't delete or erase successfully (and therefore likely cannot be written to either) it's of more concern that there's other problematic data rather than some outdated data related to earlier maps.

Does GarminDevice.xml properly update after each boot-cycle? Try moving it manually to a safe location on your PC and then boot the device to check it's properly re-created and compare the two files if it is. If it's not recreated properly on boot then the device certainly can't even read data in region 41.

About Audible, there are only a couple of short sample books and a Welcome audio in that folder, and you'd need to add books in .AAX file format to listen to more. Nobody ever seemed to use it much to listen to audio books on Garmin devices anyway in my experience but if you want the original files here's the zipped folder: [Only registered and activated users can see links. ]

BTW, the .SUM extension is indicative of checksum files and they're not really needed even for current files so either can be deleted safely or just left there - even for old unused removed files - they won't harm anything.
