Hello 5103045017,
Welcome to Apple Support Communities!
We want to help get your devices connected using CarPlay. Let's make sure you've tried these steps:
"Connect using Bluetooth
- Restart your device.
- Go to Settings > Bluetooth, and turn off Bluetooth. Wait for about 5 seconds, then turn Bluetooth back on.
- Check the manual that came with your car for more information about how to pair with a Bluetooth device. Most cars require a phone setup on the car display.
- If you've connected multiple phones to your car stereo, try renaming your device: go to Settings > General > About > Name, and type a new name. Then try connecting again.
- Update your device.
- Make sure your stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.
If you still can't connect, contact Apple Support."

If the issue continues, try these steps next:
"First, make sure that your country or region supports CarPlay and that your car supports CarPlay. If you're unsure if your car supports CarPlay, contact the vehicle manufacturer.
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:
- 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.
- If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display.
- 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, 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.
If you still have issues connecting to CarPlay, contact Apple Support."
