I think I posted the answer to this question a couple of years ago, but my previous post seems to have disappeared from this forum.
I have the RVND 7720 model. On my GPS --
1) Start the trip.
2) On the map window, press the directions-list tab on the right side of the window (below the upcoming-exits tab).
3) Press Route Display Options at the bottom of the new pop-up window.
4) Press Summary Map View at the bottom of the Route Display Mode pop-up window.
5) A map of the entire route, start to finish, is then displayed.
