The Edge 830 came with a preinstalled base map for my region.
On top of that I additionally added Openstreetmap.
Both are activated.
Now let's assume the maps have contradicting information regarding specific paths, e.g surface type or else.
Or feature the same street but with an offset.
Or one map still shows a standard intersection whereas the other a new roundabout at the same position.
What does the 830 make out of that two when computing a route on the device or just showing the position?
Would it be better to activate just one map per region at a time?
