I use the map to make up rides as I go and stick mainly to back roads. Garmin sets the background to a light grey and then the less used roads to a slightly darker grey and it's very hard to see how the roads connect when zoomed out. I've set all of the overlays except for unpaved roads to off. Popularity map is off, high contrast is enabled, map detail set to most, color mode set to auto. I set the map scale to 0.8mi so I can see far enough ahead to know how to connect the different roads. All the "main" roads are black and show up just fine but all the other roads are light grey and near impossible to pick out on the screen. What can be done to make it so the secondary roads are shown in higher contrast color?
