It is snowing out, so I am not taking my car out soon,so cant test my theory. I'm wondering if you click on the arrow in the bottom left corner to bring up the menu bar on the bottom of the screen, then go far right to the "settings" tab in Nav., then select "Highway Exits", then "Only When Menu is Open"?
. If this doesn't work, I think I'd be hollering out "Dan! HELP!!" Now that you brought up the subject, I can't wait to find out the real answer. s.
