Sorry Michael, we missed your original question. Do you mean that Garmin Connect is only offered up as an app to "Open with" when you download a route from Plotaroute in GPX format? Unfortunately this is a feature of Gamrin Connect not Plotaroute. For some reason they've chosen to only accept GPX files in this way. To import other formats like TCX, I think you'd need to use the desktop version of Garmin Connect.
Admin - Any help you could give on this? Thanks, Mike
There are download options for the Garmin Connect software on my routes but it will only work on my iPhone if you use the GPX format. One route is: https://www.plotaroute.com/route/2037126 Is there something I'm doing wrong or how do I use other formats?
