You might be able to put a GPX file directly into the GPS unit from your computer. I assume you have the mini (not micro) USB cable for it. I assume it operates the way my Garmin 62 or 64 does.
When I connect my GPS via the cable to my windows based computer, the screen on my GPS has a weird symbol on it and the word Garmin that indicates it is connected.
From my computer, I can see two extra drives, or only one if there is no micro SD card in the GPS. On my computer, one is called D, the other E. The D drive is named Garmin GPSMAP and the model name. The E drive is named whatever name I gave to the micro SD card, if I named it.
In the drive that is Named Garmin GPSMAP <model namd>, the direcory called Garmin has a directory in it that is labled GPX. That is where my tracks, routes, waypoints, etc., are. If you have a GPX file for a track or route you want to ride, put a copy of that file into that GPX directory.
Then exit. Tell your computer to disconnect that drive. When I do that I get a note that it is safe to remove.
I unplug it and the GPS turns off.
I assume the Garmin manual tells you what to do at this point. The track shows up on the map screen, it is up to you to keep on that line.
