Using the cable and the laptop is a fine alternative when being under the right conditions, but the problem is that I can't easily wirelessly transfer another gpx file to my Zumo XT when sitting somewhere down the road on a terrace e.g. Garmin will (have to) fix it (eventually).
Understood. There is nothing more convenient than performing an app transfer. It's one of the things that's really appealing about using the MRA app for navigation.
And yes, Garmin will fix the Drive app transfer issue. They always do, but more on their timeline instead of yours. Looking forward, I was referencing life with the XT2/XT3. The XT is 6-years and 2-generations old, and existing units won't last forever. Garmin has since significantly integrated their cloud based Explore DB into the XT2/XT3 architecture. When using the replacement Tread app for route transfer, your route components are stored in the Explore DB for future recalculations. The bottom line is that it doesn't always work well. Routes sometimes get recalculated incorrectly, or sometimes not at all. The only way to guarantee your routes remain intact is to not enable the Explore DB, which means you have to perform a wired transfer.
Garmin might fix this behavior in the future, but based on their history, it's doubtful. They're moving towards a world where they want everything performed within their Tread/Explore universe, including initial route creation. I don't think optimally bringing in external GPX files is high in their priorities.
