"If CarPlay doesn't work like you expect, learn what to do.
- 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 Bluetooth is turned on on your iPhone under Settings > Bluetooth. Then go to Settings > Wi-Fi, and make sure that Wi-Fi is also turned on. Tap the CarPlay network, and check that Auto-Join is turned on.
- If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display and select it.
- Restart your iPhone and your car.
- Make sure that Siri is on.
- If your iPhone isn't detected by CarPlay, make sure that CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions. If Content & Privacy Restrictions is on, tap Allowed Apps, and make sure that CarPlay is enabled.
- Go to Settings > General > CarPlay, tap your car, then tap Forget This Car. Then set up CarPlay again.
- Make sure that your CarPlay stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information."
