I just made the City Navigator 2012.4 on my Montana visible under Basecamp and noticed something I was not expecting. When I view the map off the Montana I get shading showing up. If I view the same version from the copy loaded on my computer (Mac or Windows) there is no shading.
See examples below....
The computer version
The Montana version
Yes I know the zoom level is different, I just zoomed out more in the 2nd image so you could see the shading of the mountain ranges better. It does go away if I zoom in to 30ft but comes back at 50ft or greater.
All views were in 2D view and Basecamp is up to date on both my Mac and Win-7 PC.
I do not have any Topo maps installed on the Montana or computer.
So what is going on here?
I looked in the Basecamp settings and I did not see anything that was set different between the two maps.
