How to fix common Apple CarPlay problems

⚡ Fast fix

• Check the cable first. Use an Apple-certified Lightning cable—cheap ones often fail.
• Make sure CarPlay is enabled. Go to Settings > General > CarPlay and confirm your car is listed.
• Restart both devices. Turn off your iPhone and your car’s infotainment system, then reconnect.
• Try another USB port. Some cars only support CarPlay through one specific port.

Apple CarPlay® is a hands-free driving tool that lets you stream music, follow directions, and use more of your favorite apps while you drive—all without having to pick up your phone. Cool, right?

But what happens when Apple CarPlay isn't working? Whatever the issue—CarPlay isn’t connecting, your apps aren’t opening, or your phone is charging but the car screen is blank—we can help.

At Asurion, we don’t just fix and protect your tech; we teach millions of people how to get the most out of their connected devices. Here’s our guide on what to do when Apple CarPlay isn't working.

1. Restart your phone and your car

Are you wondering, “Why is my CarPlay not working?” Start with the simplest IT solution in the book: a quick reboot. It clears out background glitches and forces the two devices to shake hands again.

To restart your iPhone®:

1. Press and hold the Side button and either Volume button until the power-off slider appears on the screen. (If you have an iPhone with a Home button, just hold the Side button).
2. Drag the slider, then wait 30 seconds for your phone to turn completely off.
3. Turn your iPhone back on by pressing and holding the Side button until the Apple® logo appears.
4. While the phone restarts, turn your car's engine off, open and close the driver's door (to force the dashboard to power down), and turn the car back on.

2. Check your USB cable and car port

If your phone is charging but CarPlay isn't popping up, the connection is the problem.

• Use an MFi-certified cable: Cheap cables only transfer power, not data. You need a high-quality, Apple-certified Lightning or USB-C cable (depending on your iPhone model).
• Check for damage: Inspect the wire for frays, bends, or a dirty connector tip.
• Use the right port: Most vehicles only support data transfer through one specific USB port. Look for a port outlined in white or marked with a smartphone icon.

3. Make sure CarPlay is turned on

If your iPhone isn't connecting to Apple CarPlay, the feature may have been accidentally disabled in your settings.

1. Go to Settings > General > CarPlay.
2. Select your car from the list.
3. Make sure the Allow CarPlay While Locked option is toggled on. If it's off, CarPlay will fail every time your phone screen goes to sleep. (Note: If your car is already connected but acting buggy, tap your car, select Forget This Car, and set it up from scratch).

Check your Screen Time restrictions: If CarPlay is completely missing from your settings, you may have restricted it. Go to Settings > Screen Time > Content & Privacy Restrictions. Tap Allowed Apps and ensure the toggle next to CarPlay is green.

4. Confirm Siri is turned on

This is a common trap: Apple CarPlay will not work if Siri is disabled. Apple requires hands-free voice control for safety while driving.

1. Go to Settings > Siri & Search.
2. Confirm that Listen for "Hey Siri" (or just "Siri") is turned on.
3. Ensure that Allow Siri When Locked is also turned on.

5. Troubleshoot your wireless connection

If you are lucky enough to have wireless CarPlay, a wired USB cable isn't your issue—your wireless radios are. Wireless CarPlay requires both Bluetooth® and Wi-Fi to be active simultaneously.

• Turn off Airplane Mode: Swipe down from the top right of your screen to open the Control Center. If the Airplane icon is highlighted, tap it to turn it off.
• Check Bluetooth and Wi-Fi: In the Control Center, make sure both the Wi-Fi and Bluetooth icons are toggled on (blue).
• Enable Auto-Join: Go to Settings > Wi-Fi, tap the small "i" icon next to your car's network name, and make sure Auto-Join is turned on.

6. Make sure your iOS is up to date

Apple frequently releases iOS® updates to patch software bugs, including Bluetooth and CarPlay glitches. If you are running an old version of iOS, the software might be failing to communicate with your car. Check out our guide on how to update your iPhone to the newest iOS for step-by-step instructions.

7. Make sure your vehicle is compatible

If you're in a rental car or just bought a new vehicle and are wondering why CarPlay won't launch, you may have an incompatibility issue. Not all trim levels include CarPlay. Double-check your vehicle's owner's manual or look for your exact make and model on the list of compatible cars on Apple's website.
