They just want to sell their navi map updates like they used to before CarPlay was a thing.

I used to drive a range rover sport that would display a long pop up with some legalese about focusing on the road while driving when I hit the navi button. It required acknowledging.

That wouldn't be a problem if it weren't that the built-in MB navigator is by ar the best I've ever used, and definitely better than all of the apps (Google Maps, Apple Maps, Waze, Nokia Maps, TomTom, Garmin, etc...).
