Good afternoon,

I have tried newst NTU 2023.10 European maps to SD Card, but device is not recogznizing those maps with statment that maps are interruped and not usable. I would be very thankful if someone has the solution for this, thanks in advance.

EU maps unlocked?
Properly appointed?

EU NTU 2023.10 South IMG UnLocked, and does not see them

Try NT map. And pay attention to naming of folder/files on card.

I've already tried changing the NT map folder in SD and "Garmin" or "Map" and the "gmapsuupp" folder itself, unfortunately without success.

Wrong

Browse and read, I'm not at the computer right now, so I can not browse the Forum and find the proper nomenclature.

Here are some names used by Garmin OS:

gmapsupp.img – maps you download, can be both internal and external on a SD card (this name is most common, and it means you can copy it into your GPS internal memory or memory card
gmapprom.img – built in maps like City Navigator, only internal
gmapprom1.img – built in extra maps, only internal. City Navigator EU and US need two files
gmapbmap.img – base map file, can only be internal (on the GPS device)
gmapoem.imb – OEM maps, only internally

The above are found in the internal memory of the GPS

Some in .system folder and some in \Map folder

I will not spell that out you can check for yourself.

Then there are these types of map names:

example:

City Navagator Europe 2023.10 (type NTU)
D6210220A.gma
D6210220A.unl
D6210220A.img

These go in the folder (SD) \MAP (can be in the internal memory in the \Map folder too.)

Plus you can name the map Europe_South.img but the unlock has to have the same name Europe_South.unl

If you do not have unlock file then you will have to use a patched version of the map for it to work.

Make sure you do not have the same name maps that are in the memory of the GPS.
That will not work.

The name you posted is not correct "gmapsuupp".

Forget about that name and give it another name.
