965 Roundtrip planning Feature not working

ab101 4 days ago

I used to use my round trip route planning feature on my Garmin 965 all the time but anytime I use it now it doesn’t work and gives me routes of 0.2 miles. Anyone else experience this?

Tried mine and it works as expected FW23.20

When I do anything above 50-60 miles it will give the 0.2 mile results. Used to not do that, maybe it’s my location

Ok I tried a long one ( as I run mine are generally a lot shorter than that ) to see what happens. I had tried 8km.
it definitely gets confused then mine are 62 meters if I do very long ones.
I tried 21km and it worked ok.
30 k also worked ok
40k worked ok
50k worked ok
so very very long ones seem to bug out

Report it in the bug report section and email product support @garmin.com as these forums are seemingly for use-use help and any garmin rep says we'll look into it and then nothing

Thank you both! Typically not running over 60 miles lol but sometimes like to get a long bike ride in (at least 70 miles). FredGolightly could you provide me with a link to the official Garmin bug report section? I had trouble finding it, but will send them an email today

It's possible (difficult to say how likely though) that the roundtripping algorithm runs out of memory reserved for it when the distance is long enough. Those kinds of graph algorithms typically need some kind of storage for intermediate candidate paths, and there can be a lot of those if there are lots of roads or paths in the area. Of course the algorithm should still give a meaningful error message instead of a very short route.
