Navigation question
When we drive along a newer road that the nav doesn't display, a series of blue dots appear onscreen tracing our path. These blue dots seem to be retained in memory? I notice they don't ever seem to go away. We have a long winding driveway leading up to our house, and the display now looks like we live in front of a lake, with all that blue in front of it. I also see the blue area growing around frequently visited shopping centers, etc.
Is there a way to clear these blue areas?
Thanks,
David
