Solved :-)
Zooming level was set to 8 meters, so only when zoomed in to a level of 8 meters would show user waypoints.
Changing the setting to 200 meters results in all GCs showing on the map when zoomed in to less than 200 meters, zooming above 200 meters hides the GCs.
Changing to "Auto" seems to show them all the time (have to test that during some navigation).
Super tip, thnx thnx thnx :-)
