hello there, can someone explain the utility of this mysterious button in the lower right corner when you are in the Map mode (just at the right side of the "clear guidelines" button..... Thanks for any ideas

Cant see it  Picture?

The one that looks like an eraser ???

Hello Daver/m......exactly....the eraser thing :-)

The eraser will clear the flight trace line from the screen. (Wipes the whites lines from the flight path)

Great.....thanks Tim
