That is nothing Mapfactor Navigator is made for. It is mainly created for road navigation. So maps are much smaller than would be neccessary for mountaineering. For example Austria Map is approx. 100MB for Navigator and nearly 600 MB as specific outdoor map (both OSM maps).
Use specific apps like Oruxmaps and related maps as Openandromaps for walk in mountains!
When I walk in the mountain, it is very useful to have some important details like : (1) in Switzerland => cog railway between Grindelwald Grund and Kleine Scheidegg (2) in Switzerland (Grindelwald) or in France (Arcs 1800) chairlift, skilift and cableway
Through OSM (on my PC W7) these details (1 - 2) are present, but on my smartphone (Galaxy S5 - Navigator 2.1.97), these details are absent.
Do you think, you can do somethink ?
in fact, I would like to have the same details through OSM PC compare to OSM Android mobile
