Just tried it and it is like you say, thanks. Influenced by the previous version, I thought pressing back button would exit navigation.
Then one more complain: in the previous version I could get a metric scale from the labs, which I think is not there anymore. I think a map without a scale is a toy-map.
When you have searched for a destination, click on the bottom right where it shows the commute type (car, bus, bicycle, walking) and estimated time. From there you'll find a list of three suggested routes (at least I do). When clicking on any of the the suggested routes, it'll show all of them in the map and you can also choose a route by clicking on it in the map.
Additionally, I get back from navigation to route view just by pressing the back button. Works just like it should?
