The course list shows all your courses. Here you want to enable the course(s) you want to include on your overview map. So that’s normally the course(s) there is active in the course guide. This is done so there will be drawn play line points on the overview map for the active course(s). Normally you want to leave the labels and icons blank for the courses that are active in your course guide and only enable icons and labels from the overview course.
With Overview Orientation you can turn your overview, so it fits your course guide best. When you have a active overview course the compass will be active as well. You can click anywhere in the compass to point the north arrow in that direction or you can just drag the arrow around.
