No sound from car speakers.

Hey there, shrike1216!

It sounds like you're having some trouble with music playback in your car. While the song comes up on your stereo display and the phone charges, the actual audio itself comes from the phone speaker. I'm happy to help!

Based on what you've described, I'd recommend going through the following steps outlined in the Apple Support article If your iPhone, iPad, or iPod doesn't connect to or work in your car - Apple Support:

"If you connect using USB playback

1. Restart your device and your car.
2. Make sure that your device is unlocked and on the Home screen.
3. If possible, try to connect using another cable or USB port. Check your car owner's manual to learn how to connect an Apple device.
4. Check your charging port for any debris or damage. Make sure that your charging cable is inserted fully into the port.
5. Update your device.
6. Install any firmware updates for your car stereo.
7. 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."

Cheers!
