Questions about Command Navigation

Good evening together, as already announced in the thread “G 350 BT really so bad?”, I bought a 4 month old presenter, just that G 350 BT. After a week of use I gradually get closer to the operation of the many extras, although there is still a lot to learn and try out. I recently had a hard drive navi in the Porsche 997S, but I did not use it for the Iphone after purchasing the Navigon app. The Command Navi seems to be similarly moderate, wi e that of Porsche. But maybe I’m just standing on the hose and you can help me: I want to stand constantly on the navigation screen: – the GPS speed – how far it is to the next junction – how far it is to the goal – the time of arrival that is always adjusted to the speed – the permissible maximum speed All points, which are natural with the smartphone apps. In the command I only have a window to display under route for arrival time u nd rest-km found, which almost completely covers the screen. Can it be true that you can’t display the above information permanently? From the beginning of the year there is probably a command with the traffic live system of TomTom for some DB vehicles. I only found that this is not available in the G-Class (why?). Does anyone know if it can be retrofitted at least? I found a qualitatively very bad you-tube video “link car smartphone mirroring” in which the Iphone screen mirrored on the command, but it doesn’t show how to get it. Does anyone know that? Thanks and Servus, Jonny
