@Corjan-Meijerink ...I can understand your point of view.
But I feel, my question belongs to "main function". During a ride, I often want to stop navigation and restart (may with other Waypoit as starting point). It's a bit nasty with the double confirmation for stop the navigation. But if I could reach both confirmations by remote controller, I can live with.
The other question seams for me also simple: if there is still a breadcrumb navigation on the top (which is reachable by remote controller), then there is only one level missing; that's all.
My personal feeling: sometimes, it's not possible to stop the bike immediately to operate the navi device. So, most people do it while riding. But since I use a remote controller - I still do only the really needed operations on navi - but I feel much much more secure by this.
As I often tell: it's the biggest game changer I experienced ever...
