@Hans-van-de-Ven-MRA-Master Dank je. (kwam er inmiddels achter dat het niet is met HERE kaarten om het nog ingewikkelder te maken)

In several routes made in MRA the routepoint no.6 is giving troubles. If 6 is the endpoint, it is not seen; so 5 is the endpoint. If it is on a route there is a straight line between 5 and 6. To avoid this I place 6 just behind 5. First I thought it was the Zumo criting the fault, but with the GPX viewer app I see the fault already on the PC when saving the GPX.
This error is quite new, did not have it before (till a month ago or so).
