My fenix 5x did round trip navigation two days ago, but after updating the maps in garmin express it will no longer plot courses. Instead, the screen will display the message, "maps do not have routable roads in the area"
Interesting, I must test this further because I typically have the pre-installed cycling map (which I believe is routable) plus an OSM map (which states it is routable) both on at the same time. As far as I know it doesn't cause a problem but I see your point. How does it choose which to use?
And an interesting observation. During a test I turned off all maps in Navigate so had no maps 'on' and I tried the
navigate->round-trip
thing where it makes a route for you based on distance and starting direction. It still managed to come up with 3 routes for me to run despite having turned off the maps. Maybe 'turned off' isn't really completely off, maybe just 'do not display'
I don't think that either of those is routable. Not sure about the Topo US because I am in Australia and don't have it but the Topo Aus and NZ that I got with my watch isn't routable. However, the watch came with a cycling map that is routable so maybe you are missing something like that somehow?
You can get routable maps from Open Street Maps (OSM) and install them if you can't get the issue sorted out in a conventional way (i.e. get Garmin Express to fix its screwup)
