Import GPX tracks onto Zumo XT2

Sorry if it's discussed somewhere but I can't find it. I am trying to import GPX tracks as *tracks*, not routes, onto my Garmin Zumo XT2 and the device keeps converting the tracks into routes. I saw that Garmin Tread app does this and that the way around it is to copy the raw GPX file to the device via USB transfer so I did that. But then when I turn on the device it notices the GPX file and asks if I want to import it, which I do, but then it converts it into a route.

All I want is like my 680t -- select GPX tracks to display on the screen as lines with no routing. I can't hear the speaker, anyway, and I need this to work while offroad and therefore unroutable.

Any hints?

Thanks!
