If I understand correctly, you are having trouble connecting your iPhone to your car using Apple CarPlay. It seems like you have already tried using a different USB cable to connect with. If that hasn't worked, have you tried to connect using Bluetooth?
- Update your iOS device.
- Install any firmware updates for your car stereo.
Try playing audio from a different app. If you can't play audio from a third-party app, contact the app developer for help. If you can't play audio from an Apple app, contact Apple Support.
If your car supports wireless CarPlay, press and hold the Voice Control button on your steering wheel to set up CarPlay. Or make sure that your car is in wireless or Bluetooth pairing mode. Then on your iPhone, go to Settings > General > CarPlay > Available Cars and select your car. See the owner's guide for your car for more information.
