@ericbuijs @pocketvj I noticed that the maps on my
#Garmin Edge 530 were dated 2019, and the Garmin Connect Android app didn't offer to update them (I updated the firmware through it). I bit the bullet, as I currently have a Windows PC at home (employer owned CAD workstation), so tonight I installed Garmin Express and updated the maps. I find it silly to not be able to do it with the mobile app.
My Edge saves routes in FIT format. I found
#GPXsee, an open source Linux map viewer that can import gpx and FIT files (and a few others). Unfortunately it cannot export them to gpx. But I found a Python library that apparently does, I'll test it out soon.
Garmin Express has been known to install successfully on Linux with Wine, although the latest entry on the WineHQ db reported failure. Somerhing to look into in the long run. Worst case is I keep the device as is.
