The maps in Garmin Explore are totally useless with lack of details. Users have been waiting for years for Garmin to add usable maps. They have outdoor watches, but their use is limited because official app does not have maps that can be used for outdoor activities. In many places (like in Finland) there are free topographic maps available, Garmin has to only add them to the Explore app. Or at least make it possible to users add those maps.
All other outdoor apps have better maps than Garmin, and after all Garmin has a very long history with GPS-systems and maps so it's a shame that they don't develop maps for Explore app so their users would get the best out of their watches.
