No, srtm isn't updated yet, but most the other layers for Germany are.
But where is the problem?
C:\Garmin\Maps\TK-OSM-DE-Basesystem\Uninstall.exe
C:\Garmin\Maps\TK-OSM-DE-Hiking\Uninstall.exe

You don't need to put them in the same directory, only the $REG_KEY
needs to be the same.

You don't need if you choose different directorys.

That was my first idea, but in the end, I had to struggle with
too many possible file conflicts and making sure, not to delete
a file still needed by another map, that I decided to use different
directorys.
MapSource and BaseCamp don't care about where the files are on
disk, only where the registry entries are.
