One remark still to the previous version of the map in previous (already closed) discussion thread - regarding map "Garmin Recreational Map of Europe 3.00 - MapSource". If you attempt to install it into the Mapsource v 6.16.3, please use the file "install.bat" contained in the map directory "Family_469" but you need to edit the registry path in the "install.bat" file from "HKLM\SOFTWARE\Wow6432Node\Garmin\MapSource" to "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Garmin\MapSource". Then it works.
