What you see on your device as background is the colored Basemap, which changes from green for valleys to brown for mountains.
Add a solid background color of your choice to the original TYP (polygon 0x10d 01 (NT) with DrawOrder 01) and your Basemap is going to disappear!
Another "brown" problem with Topo Maps is that Garmin gives a "default" brown color to the Height Contour Lines and they are ...too many!
So you have to add to the original TYP the 3 Contour Lines categories (for NT) but you have to be very careful with the color of your choice, so that it is not a color that other lines have in the map.
Rep points 2U for the best single answer!
