I don't know what a "course" is, and I haven't looked.<br></blockquote><div><br>Courses are supported by training/racing-oriented Garmin devices and add timing information, to allow better time estimates, and to give the user a target time.<br>

In summary, if you want to go somewhere with the GPS then plot the route<br>
on your map and make a GPX file containing a "route". Download the route<br>
to the GPS and it should do the rest.<br>

- Can be as long and complicated as you like<br><br>Route:<br>- Gives better instructions ("left at the next roundabout") etc<br>- Easier to create and manage<br><br>I tried both this weekend and found routes weren't reliable enough. Sometimes you'd get a "route calculation error". Also, my GPS doesn't support routes with more than 50 waypoints. It seems a lot simpler just to create a track and be done with it.<br>
