Why does my iPhone not play music or audio through my car's stereo? My friend's iPhone plays music, YouTube, etc just fine through my car's stereo using the USB cable. But my iPhone won't. I have reset and restored my phone. Even after I got a new iPhone it still doesn't play. Why would that be?
Download a song through iTunes. That is all I had to do. Apparently my car's stereo won't play any audio from any app unless I have at least one song in my iTunes library. I listen to everything through streaming services like Spotify so I didn't think I needed a song in my iTunes library.
