Can the NUVI 500 be updated to increase the Map Detail of secondary roads? My old GPSMAP 76 shows secondary roads sooner and over a farther area than the NUVI 500. An it has a smaller screen. I don't need to see the road names just the lines. Also, can the color of the secondary road be customized? They are hard to see against the green background when in track up mode.
Changing the secondary road color in the day mode to the color in the night mod wold help.
Edit: One time the green background in 2D changed to white and I could see the gray secondary roads. But it must have been and error because when i switched to to 3D and back it was green.
I noticed today some of the secondary roads are a dark color and can bee seen. Why not all?
Thanks
