If carmakers have realized that the worm has turned, they can ditch both the hardware and software by offloading onto the smartphone. Pretty good guess that anybody buying a $$ car has a smartphone, and replacing a smartphone is way easier than replacing a piece of the dash. Maybe dealers hope people will replace cars every 2-3 years rather than drive around with busted dash hardware? All that's needed is a good audio system and a means of connecting to the smartphone. And, if people aren't into really good sound, then a not-crap audio system that can play voice well.
