If you follow Round-trip course: The watch vibrates (give a alarm) at an upcoming turn and shows the map. It also show how much meters you get the next turn.
In the past this functionality was also when you follow your own course. Currently this does not working anymore.
I asked the Dutch support of Garmin about this feature. They told me that Garmin is working hard to get this feature back, but that is some weeks ago.
When can we expect this feature back in the watch?
