I'm using Garmin Express 7.1.4.0 to update the City Navigator South America map.
After the download, my Garmin Zumo 395 GPS receives the 2021.20 version
BUT
my PC receives the 2021.10 version.
I've investigate the downloaded files and I've found the folowing folder hierarchie:
C:\ProgramData\Garmin\CoreService\Downloads\Map\Map_Map.SAm.2021.20\RMU\SAm\2021_10\...
When I open BaseCamp I find City Navigator South America NT 2021.1
