I just don't understand the need for "infotainment" in cars. I carry a screen in my pocket that I mount to my dashboard. It does a much better job of navigating me around and enabling me to talk to people than any goofy head unit with UX designed at a car manufacturer ever could. All I need in a car is a knob for the air conditioning and a knob for the volume. I still just use a single din aftermarket stereo that plays music from an SD card. I will never have anything more. I will drive cars as old as myself if I have to for the rest of my life before I allow some car manufacturer to push me around.
