Thread: Nüvi 3790

Hello Garman, I'm glad to know that someone has been interested in this recovery.

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

I don't know where you got this serial number from, my Nüvi model, it has never been this one. Could it be that there is something corrupted in the serial number and that is why my nüvi does not work well as a nüvi 3790?

I don't know if I'm right or not, but I still think that the LM map update was offered to me after I downloaded the unlocked map files from the internet and copied them to the nüvi. Before, whenever I connected to Garmin Express, if I wanted to update the map, I had to pay for the update, I think it cost €99.

Thank you for your help, I now it. I think, that the PC files, aren't necessary, because if there are a copy all the folder and files of the nüvi, is sufficient, Relay?

Greetings

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.
