Hi, Tory,
Thanks for visiting the Apple Support Communities to get help using CarPlay in your 2020 VW Golf. Troubleshooting for a variety of CarPlay issues can be done by following the steps below from If you need help with CarPlay - Apple Support:
Make sure that your iPhone has the latest version of iOS. If your iPhone is updated to the latest version of iOS, follow these steps — checking CarPlay after each step:
1. Check your connection to your CarPlay stereo:
• If you have a wired connection, try connecting again with a different USB cable to a different USB port if you have one.
• If you have a wireless connection, make sure that Wi-Fi and Bluetooth are enabled under Settings > Wi-Fi and Settings > Bluetooth.
2. If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display.
3. Restart your iPhone and your car.
4. Make sure that Siri is on.
5. If your iPhone isn't detected by CarPlay, make sure that CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions, tap Allowed Apps and make sure that CarPlay is enabled.
6. Go to Settings > General > CarPlay, tap your car, then tap Forget This Car. Then set up CarPlay again.
7. Make sure that your CarPlay stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.
Since the issue is isolated to outgoing audio while connected to CarPlay, we would also suggest reaching out to VW directly to find out if there are any issues with your Golf's stereo system.
If you still need help after that, please get in touch with Apple Support directly. You can do that here: Get Support.
Have a wonderful day!
