Hi Dutch Guy stuck in Norway,
First, you should register your serial number so that you can access the Missions board where questions about missions should be asked. On that board, you can download the Missions Manual, which answers your question and many others.
Free sample: There are buttons below the chart that select various items to be displayed on the chart. One selects waypoints. It’s second from the left, as I recall.
Regards,
Marty
