Yeah, that's the theory... unfortunately, the reality is different. To load a route into the app requires internet. Try it. Disconnect wifi & data. Select a gpx track that already exists on the phone /tablet. You cannot get it into the app without internet. (According to Wahoo it "pings" or "Checks in" to the Wahoo cloud database. No internet and you get the message about a corrupt file.

What I don't understand is that there is no need to do "check in" when the file is transferred by cable directly to the unit. It just works.

So, what software is it that sits on my laptop that lets me see the Elemnt device as a separate drive that is missing from my tablet?

Thanks for your input!
