Anyway, I took the risk and flashed R59!
It was problem-free, no star key bug or anything like that! What I immediately noticed:
“Faster” boot animation, generally faster reaction of the infotainment
sometimes different dialogs: "Please plug in the charging port to charge" wasn't that called something else on the R46?
quick access to switch off LKA (pulldown menu)
Charging planning is only possible on the second page, nothing is planned directly in the navigation system
+49 Bug seems to be gone too
Amazon Music is working again!

Load planner in action, can also be adjusted at what % should be charged, what % arrive at the destination, etc.
The only disadvantage is that the hotspot really doesn't work, but I personally have never needed it.
