Can’t play music through car USB port
Hi, I have an iPhone SE (iOS 12.3.1) that has always played music perfectly through a USB cable plugged into my car’s port. Yesterday, my friend plugged her iPhone 5 into my cable to try and play her music. The phone connected, but when we tried to play music no audio came out (even though the song said it was playing on her phone). I then plugged my phone back in but the same thing happened. It connects, shows that it’s charging and playing music, but nothing plays. I’ve restarted my phone, unplugged the USB, turned my car off and back on, messed with all volume settings, and nothing worked. If you could please help I’d really appreciate it!!!
iPhone SE, iOS 12
