I really like the Noeman site. Good downloads but the best part is that info is well organized and if you spend some time, you can get all the info you need. Credit to both uploaders and moderators.

"SouthAmerica_2012_40.img" is actually the original file name directly from Garmin. Newer Garmin units that have extra maps in "[UNIT or memory card]:\Map" directory will get this file as "[UNIT or memory card]:\Map\SouthAmerica_2012_40.img" when downloading from Garmin.
Older Garmin units may have to store the map in the Garmin sub-directory instead and rename the file to "gmapsupp.img" or "gmapsup2.img" or "gmapprom.img" or "gmapprom1.img". All depending on the type of unit and the usage of other maps with their existing file names.
You may check the "[GPS unit]\Garmin\GarminDevice.xml" file and see if there's a NMaps tag and a location of those maps. If so, then you can use any file name in that location as long as the extension remains IMG.
