I get turn by turn navigation on my Edge 800 and on my (Garmin) wrist watch.
Use RideWithGPS to create a route if you want to plan one in advance. Export as TCX. I have to convert to FIT to get turn by turns in my watch but I think the Edges don't require this step. But it has to be TCX, a GPX file isn't capable of holding the information to do it right.
