But I still cannot add the map data to the XC Soar. In the setup
system window #1 "site" when the map database box is tapped, an
empty screen is shown. It looks like the .xcm map file should be
listed here,but it is not.

It is added to the program file's next to XC Soar,but will not transfer
over.

Did you copy the .XCM file to the XCSoarData folder? The XCSoar
manual describes this in detail.

To help you further, I need more information about your setup - what
device? What operating system? Where and how did you install XCSoar?
Where did you copy the other data files? etc.
