Question about Garmin fenix 5X Sapphire Edition

You can also enter the coordinates of the destination under Navigate. However, you have to look up the destination coordinates in Google maps, for example. However, I would say that navigation is easier with an iPhone. However, the map display on the navigation screen is amazingly good as an orientation aid.

Yes, this is possible. Under "Navigate" a destination can be selected on the map. Thus, not directly a street, but a point.
