When a course is loaded, this works fine. A dot shows your position on the green sloped "hill", which scrolls to the left as you ride.
But I would expect this to work the same way when you use the 830 to navigate to a location. It does not. No dot. The map shows you where you are. The screen shows some kind of change that is seemingly related to your ride. It does change, and scrolls to the left, but with no dot.
In a related matter, if you are riding with no course or no navigation, same thing. The elevation screen is showing something, it does change. Does it mean anything? Does it show past elevation, since the data could show where you have been, but obviously not where you are about to go.
