Got it, josedebardi, thanks. When you open Navigation, before setting a route, the four corner buttons are (clockwise from top left): Memory, Route, Settings and Map. Once you set a route and the map comes up, the labels for the top two buttons (Memory and Route) disappear but, unknown to me, the buttons are still functional. So, if I press Route while the map is showing, there's a sub-menu for 'Nav Info' and, when you scroll down, there's distance and arrival time for all Stopovers and the final Destination. Result.
Just surprised that distance and arrival time for final Destination are not up front on the main screen, along with distance and arrival time for the next stopover. That's the way it is on my old, portable TomTom. Like many things on the S1, the tech seems to be previous generation.
