If you go to Settings/Maps, what version map(s) does it show that you have now? It may look like 1090.11445 (Classic) or it may look like 2022.03.43764 (NDS).
Not knowing if your device is using 'classic' or 'NDS' maps, I can't yet say what the download process will look like since that depends upon which you have. NDS allows you to update each map segment separately. 'Classic' requires updating the whole map at one time.
Once we know this we can try to walk through the process.
That is an old NDS style map.
Now that I know that, let's see what we can do.
If you select Maps from the menu, is there something at the top that says "Your active map does not support updates" (or however that translates in your language)?
If not, what do you see on the far right side of the page across from each map segment in your map list?
