Garmin Topo Maps

[groschi2]

please don't kill me if this topic is allready treated in this forum. I nearly allways use the openandromaps with oruxmaps. Sometimes not all ways are shown in the OSM. Often before I start a trck I plan it with mapsource. In mapsource I also use garmin topo maps. In germany I can use garmin topo map until version 10 with oruxmaps. In Italy I can use treck map italia v2 with oruxmaps. It's not possible to use German topo v6 pro or v7 pro or trekmapitalia V4 pro (any pro map).

Is this normal? Isn't oruxmaps able to work with pro maps from garmin or is it my mistake because I make my maps with mapsource. Mapsource isn't supported since a few years. I also have BaseCamp but I doesn't use it because using is terrible.

Does anybody know whether there is an option to use newer garmin topo maps?
