When you start the routeCourse app on your GPS it will show you a list of your "cloud" routes, which are the routes (sometimes called courses) that you have created (or imported) and stored online in your dynamicWatch account.
Tap (touchscreen) or use the Up/Down and Select buttons (Edge 520 and watches) to select a route to view its details, and download and "launch" it in the GPS's built-in activity/map feature.
If you press Download then the route will be downloaded and added to your Garmin's built-in Courses list. If you press Download and Launch then the route will downloaded (and added to your Courses) and routeCourse will hand the route over to the built-in Ride activity app on your Edge (or other activity type if you have an Oregon, Rino or GPSmap66) so that you can immediately start it. This is the usual map and activity recorder capability of the GPS that you are already familiar with.
After a route has been downloaded, the icon next to it will change from a cloud to a rectangle to show that it is now on the Garmin device.
By default, the route list is sorted to show the nearest routes first. You can use the menu of the app on the main routes list to choose other sort options (nearest, newest, longest or name).
Using routeCourse when offline
routeCourse needs a data connection in order to work. However, as explained above, any route that routeCourse has downloaded is added to the normal, built-in Courses list on your Garmin, so you can choose a route to use from there when you do not have a connection.
Turn by Turn Directions
If you have our Premium option, routes from Ride with GPS can have course points that are included in the routeCourse download, as are course points contained in TCX files from other sources such as Plotaroute and Gpsies. A route may have up to 200 course points on an Edge.
If a route downloaded by routeCourse does not include "cue sheet" directions (also know as course points) your device may be able to generate them using the built-in maps.
On an Edge 820/1000 (or an Edge 520 with maps installed), you should be able to enable "Turn Guidance" and "Off Course Warnings" in Course Settings.
