Once I enter a destination, how can I make it stop navigating and just show the map?
should be able to open the menu and hit stop navigation, if you are in the navigation menu just go back to home then to the maps app and try there
That doesn't work. It would always go back to the map with the start and endpoint selected. I did just find that if you go to "layers" then select "clear map", it'll clear everything including the navigation.
Guess that's the only way to do it.
