The OSM maps are used in a class of its own: forest paths, bike paths, because apparently lacks nothing. With OsmAnd one would actually from any forest or unknown terrain again to find out. The GPS Genaugikeit like Android, on a Blackberry Z10 but it is rotten: there used but better the BlackBerry version of OsmAnd, which is also exactly. For me, the navigation menu is too cumbersome and the detailed maps quickly too confusing, because there are better apps especially for the car. But for me to gain an overview and without internet connection, but I have installed my OsmAnd and so it suits me well. By the way: the maps are stored locally on the best / an SD card, because there come quickly a few GB together when you download the maps of several countries or installed from journals.
