Sorry for the n00b question, but...
I have an Edge 205 (so no maps) and have put together a series of waypoints in marengo so that I can follow my planned route tomorrow. This is the first time I have done this, having previously just used courses following the wiggly line.
Anyway, my, hopefully, simple question is, can I turn my garmin on when I am somewhere in the middle of the route and start navigating it from there, or will it just point me in the direction of the first waypoint back at the start? The reason I want to do this is I am not sure my battery life will last as long as it will my take me to cycle the route. Would I be better splitting the route into separate bits or will it work as is?
