I just started using Basecamp on my Mac with my new nevi 1300 that replaced my street pilot 2620, which I still have.
The problem is that when I look at a map by zooming in and showing greater detail, major highways are doubled. It's weird, the highways run almost parallel to one another where one line is curving and follows its true path while the other is straight and angular. I have tried my best adjust the settings but to no avail. I decrease the detail and the problem goes away but then I don't get the detail I want, such as the very minor roads.
I have the latest Basecamp software and updates along with the latest map updates.
Any help is greatly appreciated.
Thanks!
