Installig in Mapsourse is not a problem. There are many ways and I did it many times with different maps. Problem begins after installation: a map doesn't look like a map only pieses of different regions. Ex. in Moscow you can see its north-west and south. Other parts are missing. I tryed Mapedit as alternative program but it says "map is not comlete" and refuses to load. I have not tryed to install the map to a device (I have rather aged Garmin IQ, but if it's still working why not) but I see this map preview for the first time.
