I have been enjoying great audio in my car by using the standard USB-A to Lightning cable (same as used for charging) for years now. Seems that this somehow is broken or changed after iOS13. Now, when plugging in, the car display reports “No music files could be found”, kinda like it expects an iPod. I have no files in Apple’s Music app, so that is correct as such.
However, earlier I would just connect, select USB as the source and could send any audio, from Overcast, Spotify, Tidal, whatever, and the audio would be processed through the car’s audio system. When plugging in the cable, the car also correctly identifies the phone model, so something is working… Just no audio, even when I play a track (the seconds are ticking by on the phone display). Bluetooth is OK for talk podcasts, but music sounds WAY better over USB in my car.
Using an iPhone 11 Pro on iOS 13.3, and had the same issue on the iPhone X on 13+ too. I’ve tried all the obvious stuff, re-starting phone, using a different cable etc.
Any ideas on where to continue the troubleshooting? Thanks!
Also - have a Happy New Year
