Question about Garmin fenix 6 Pro

TopoActive are of Europe. Basic maps (with the main roads) worldwide. If you are going to the USA and want to use the maps there, I recommend downloading free OSM maps to the fenix (relatively easy, e.g. with the instructions from DC Rainmaker).

German is clear. In my opinion, maps are available worldwide or can be downloaded. But it is not comparable with car GPS.
