load a gpx onto the satmap, zoom down to 1:3K and set to orientate the map to the direction I am riding.
Normally works pretty well although I might have to tart up the GPS before I go.
For example if they double over the same piece of track twice in different directions, etc, I may need to ensure that the tracks are separated enough to distinguish the direction I should be riding, without having to stop and peer at the map.
The satamp is good as I can move around the map, a 1:25K OS map, to look what is near me. Not sure how good the garmin edge range are for this.
The worst bit though is that I don’t learn the area very well as the map is rotating with direction – it is like a car satnav. I would be better having it not move to the trail direction and stay North up – would be better for my orientation.
