@Serge-e I copy the English translation in here. I think that you then get more response.
Regarding the first question:
I also have missed the "tomtom vieuw" and hope somebody will answer. That view shows a three dimensional view of the map as though you are driving through the landscape. The dynamic mode (which you get by clicking on the compass) is close but not quite the same I think.
TRANSLATION:
"I need your help to show me how to display the MyRoute App navigation (on my Carpuride - Android Auto) and therefore the progress of my route in a dimension that allows me to anticipate turns, as can be done on my TomTom. Indeed, for the moment, I still haven't found a way to display the progress of my route in a dimension in which the route appears "finely" and not in a zoom that displays either a large, short line that gives me no visibility of the route between my points, or the entire route with all the waypoints but aggregated into a small image. So I simply want to display my navigation in a dimension close to that of TomTom or Garmin GPS devices, but no matter how hard I try to change the zoom or line thickness settings in MyRoute App, I always get a large, short line! So how do I do this?
Another question: shouldn't the route be displayed on a horizontal screen? Additional question: How do I switch from vertical mode (e.g. on a smartphone) to horizontal mode on Android Auto? Thanks in advance for your answer."
