Does edge 520 plus not do a basic reverse course, ie go back the way I came? I tried back to start and neither most direct route or along same route did that? Any ideas?
It should, but that there are some errors in the current map that may prevent it from working. I'm told that they are fixed in the 2018.20 release of the maps that are due out soon.
The first time I had selected the “along same route option” and it kept wanting me to u-turn and acted like it wanted me to continue the original route. The next day I tried again and selected “most direct route” of course it wanted me to take a different t route than what I came out on. And even as I was less than a mile from my finish it wanted me to u-turn which would have been way longer. I’m not sure what it’s re-routing calculations were doing.
