I opened a new discussion as the subject of "USA/Canada Trailforks maps on European Garmin Edge 530?" that covered the same is misleading and the dicussion in the meantimee very long.
Unfortunately I am still on Trailforks 2018.20 and not on 2019.10. The update to Garmin Edge 530 version 4.10 did not help either.
If anybody does find a solution for this so that I see all those 4.10 enhancements that are linked to the latest Trailfork maps this woudl be great.
