Maybe it’s like that time Apple thought everyone wanted that awful free U2 album that they automatically added to everyone’s iTunes library. (I know this isn’t actually the case but it’s the funniest explanation)
On my Iphone. I removed the music app. and was unable to play music in my car with the usb interface. It had no app to play from. VLC must use the music player in some way to play the audio. This is without carplay btw. Im pretty sure carplay is differnt.
