My goal was to be able to get turn notifications on routes so i don’t have to constantly look at cue sheets.
This is a work in progress and may change
First create your route on ridewithgps.
Then click on the export tab, choose GPX Route (.gpx)
Open the .gpx file in Garmin Base Camp and right click on the route name and say send to device.
On the Garmin Edge 305 it should now show up under Navigation -> Routes
