TOMTOM map install HELP

Need your cooperation, and for several days I am trying to install maps for my GPS TOMTOM Brazil and I did not succeed. I leave you a picture of the data shown on my GPS to see if you are able to say that Brazil is the map that I use and how to install the map.
From already thank you very much for your attention.

If you follow the instructions provided it will work.
If you provide all the info we need, we might be able to provide help.
We are not clairvoyant here.

Abcdefghi.

My apologies. I deleted the picture in post 1, because it contained info about your device that you should never post, such as your device's UniqueID & Serial Number. I had a short notice call come in & had to quickly leave before I could reply to your post. I deleted the picture in post 3 for the same reason.
The picture showed that you currently have an Argentina_Mapear map installed. The update for that map is Argentina_Mapear v905.4776.
If you need a Brazil map, use Brazil v905.4754.
Download & unzip the new map. Remove the old map folder from your device. Copy in the new map folder. Patch it with FastActivate 09.03.2013
Patch the 9.465 navcore by replacing the current ttsystem file with this one: 9.465 SE ttsystem.rar
Disconnect & reboot.
Done.
