Been trying to help some people to get their Garmin not to send them off course, or tell them they're off course when they're not.
My standard answer is use a track not a route, and don't let it calculate, just follow the line on the map.
But then I discover that their edge units (e.g. mainly 705s, possibly some 500s) take TCX rather than GPX, and they don't use either a track or a route, but a "course". Is a course more analogous to a track or a route?
They often don't want to delve into technical details, like I do, they want it to "just work", which is fair enough I suppose.
What's some simple steps to get a 705 working in "follow the line" i.e. track mode, rather than calculate route mode?
It would be nice if I could say "here you go, there's your line - keep an eye on your unit and follow that" but I can't cos what works on my etrex doesn't on their edges.
