However, after upgrading to iOS 18, many users have reported issues with CarPlay not working properly, such as failing to connect, CarPlay apps won’t open properly or you can’t hear anything when CarPlay is connected.
While frustrating, these glitches can often be resolved with a few simple troubleshooting steps.
In this guide, I will walk you through 9 step-by-step solutions, starting with the easy fixes and progressing to more advanced troubleshooting methods.
Follow along to get CarPlay back up and running smoothly on iOS 18.
Possible Reasons CarPlay is Not Working
CarPlay might stop working due to connectivity issues between your iPhone and your car’s infotainment, which can stem from faulty USB cables or unstable wireless connections.
Sometimes, software glitches or misconfigured settings on either your iPhone or the car’s infotainment system can also cause this problem.
Try each of the following solutions to resolve the issue with CarPlay.
Step 1) Verify Your Car’s Compatibility with Apple CarPlay
If you are trying CarPlay for the first time, ensure your car supports the feature by checking the user manual or the manufacturer’s website.
Remember that some vehicles might only support CarPlay via a USB connection, which can lead to issues if you try to connect wirelessly.
Step 2) Ensure you are Using the Right Cable
For those using a wired connection, it’s crucial to use a cable that supports data transfer. Not all USB-C or Lightning cables are created equal some are designed only for charging.
If CarPlay isn’t working but your phone is charging, the cable could be the problem.
Try a different cable to ensure it’s compatible. It’s best to use the one that came with your phone or another high-quality, data cable.

Note: When connecting via USB, ensure you use the correct port. Most cars have multiple USB ports, but only one can charge your iPhone and transfer data for CarPlay. Check your vehicle’s manual to identify the correct USB port.
Step 3) Allow Carplay in Screen Time Settings
If you have set up Screen Time restrictions on your iPhone, you might have unintentionally disabled CarPlay.
To check if this is the case, follow the steps outlined below:
Open the Settings app and go to Screen Time. Scroll down and tap on Content & Privacy Restrictions.
Then, navigate to Allowed Apps & Features. Enable the toggle next to the CarPlay option, and finally, enter your Screen Time Passcode.

Then, choose Forget This Car and confirm by hitting Forget.
After that turn on your car and access the multimedia system. Depending on your car model, navigate to the Bluetooth settings, which may be located under Phone, Bluetooth, or Settings.
Look for your iPhone listed among the previously paired devices.
Highlight your iPhone’s name and select it. You may need to press an options button (often represented by three dots or a gear icon) to access more settings.
Find the option to Delete, Remove, or Forget the device. Confirm the action when prompted.
After that again Pair your device with your car.
Step 6) Disable VPN
If you use a VPN on your iPhone, it could interfere with Apple CarPlay. Disable the VPN and see if that resolves the issue.
Go to Settings > General > VPN & Device Management.
If you have a VPN enabled, disable it and check your connectivity with CarPlay.

Try performing a force restart, as it often resolves temporary glitches that may affect CarPlay functionality. Here’s how to do it:
- Press and quickly release the volume up button.
- Press and quickly release the volume down button.
- Press and hold the side button.
- Release the side button when the Apple logo appears.
