What folder do you prefer?  BaseCamp installs folders for Maps in a number of locations:

C:>Garmin>Maps

C:>ProgramData>Garmin>Maps

C:>Program Files (x86)>Garmin>Downloaded Maps
C:>Program Files (x86)>Garmin>BaseCamp>Maps
C:>Program Files (x86)>Garmin>MapInstall>Maps

The first location seems like a good choice for either 32 bit or 64 bit operating systems.

The second locations contains a mapset formatted differently than the standard .img files.

I don't understand the redundancy of the last three locations.  Duplicate copies of the Global Application Base Map v2.gmap folder occur in the last two locations.

I downloaded and installed more than 40 state topo maps from this website - thank you very much!  All of them appear in BaseCamp under the Maps tab on my PC running Windows 7.

From BaseCamp, I transferred as many maps as I could to my eTrex20.  It filled 2.39 GB out of  3.63 GB of internal memory before it ran out of enough space for another complete map.  All of these maps appear in the eTrex20 under Menu>Setup Map>Map Information Select Map where they can be enabled or disabled. 

I  bought a 32GB Sandisk Ultra PLUS Micro SDHC card from Best Buy.  The rest of the maps transferred to this card, using 6.21 GB of the 29.7 GB of space.  The process created a folder on the card named Garmin which contains the maps and a document named Id.txt.  The Garmin folder also contains a folder named GPX which is empty.

None of the maps on the MicroSD card appear on the eTrex20 under Setup Map>Map Information Select Map.

Any suggestions?  I searched the Knowledge Base here, but most people had the problem of using a 64 GB cards that was solved by reformatting it to FAT32.  That is not the case for me because my 32 GB card is already supposed to be FAT32.  One of the answers suggested that the user copy the GarminDevice.xml file to the MicroSD card, which I tried, but it failed to make the maps appear.
