A widget below the signpost proposes, by default, the four nearest places from these categories: fuel stations (or charging stations), parking lots, and rest areas. You can add such a place as a waypoint in one tap. Tap the hamburger icon to view more places, or collapse the widget by the arrow.
You can change which categories you would like to see. Go to the Menu – Settings – Notifications – Places along route. Use the toggle to enable the categories you want to see in the widget or to disable the categories you don’t need.
