This. My car (Porsche Panamera from 2013) runs QNX for its nav+soundsytem. I can stream from bluetooth or use a jack plug but I don't bother: the car's got its own storage for music and, notably, the system takes both .mp3 and .wav files, but not .flac files. So at home I play .flac files but for the car I convert my music to 320 kbps .mp3 (I think I can put about 5000 320 kbps .mp3 in the car). In 2013 Porsche was still putting HDD and not SSD in their cars: some people do the upgrade themselves to a SSD but in my case that would void my extended manufacturer warranty (which I plan to extend up until 15 years / 200 000 km). Since then, for newer models, the manufacturer has moved the nav+infotainment to Apple's iOS CarPlay. I don't know if QNX is still used for other stuff (like reporting the oil level / warning messages etc.).
