Part 3. How to Fix iPhone Not Connecting to CarPlay

Many drivers experience issues when trying to link their iPhone to their car, whether through a Lightning cable or wireless connection. The good news: connection failures are easy to solve with the right troubleshooting steps below.

Solution 1. Check iPhone and Car Compatibility

Not all vehicles support Apple CarPlay, and some vehicles only support wired or wireless versions—not both. Besides, CarPlay requires iPhone 5 or newer with iOS 7.1 or later, but wireless CarPlay typically requires iPhone 6 or later running iOS 9 or newer. If you're using wireless CarPlay, confirm that your vehicle supports wireless connections. If compatibility checks out, proceed with the troubleshooting steps.

Solution 2. Enable CarPlay in iPhone Settings

Sometimes, CarPlay may be turned off in your iPhone settings. If your iPhone doesn't allow CarPlay, it won't initiate a connection, even if everything is fine. Also, make sure that CarPlay is allowed when your iPhone is locked. Follow the steps below to enable CarPlay in iPhone settings.

Step 1. Go to Settings and tap General > CarPlay.

Step 2. Tap your car's name and switch on Allow CarPlay While Locked.

Solution 3. Check Your USB Cable or Port

For wired CarPlay users, a faulty USB cable is often the main culprit. Always use a certified Apple Lightning cable and avoid third-party cables that are not MFi-certified. Also, some cars have multiple USB ports, but not all support CarPlay. Try plugging into another port. And inspect for dust, dirt, or debris inside the port. If CarPlay works with another cable, replace the faulty one.

Solution 4. Reset Your Wireless Connections

Wireless CarPlay requires both Bluetooth and WiFi to function correctly. If your iPhone doesn't connect wirelessly, you can reset the wireless connection between your iPhone and car. Here's how to reset the wireless connections.

Step 1. Go to Settings > Bluetooth, forget your car, and repair it.

Step 2. Go to Settings > WiFi and ensure WiFi is enabled.

Step 3. Restart your iPhone and car's infotainment system.

Step 4. Hold the voice command button on the steering wheel to reconnect CarPlay.

Solution 5. Restart iPhone and Car System

Restarting your iPhone helps reset all background processes, including those responsible for connecting to external devices like your car. If a system glitch in your car's infotainment system is causing CarPlay not to connect, a quick restart can refresh your car.

Step 1. Restart your iPhone by holding the power button and sliding to power off.

Step 2. Restart your car's infotainment system.

Step 3. Reconnect your iPhone to your car again.

Solution 6. Check CarPlay Restrictions in iPhone Settings

If CarPlay is restricted on your iPhone, you won't be able to connect, no matter how new the cable or car is. Screen Time Restrictions can silently disable CarPlay, especially if you're using a work phone or have parental controls in place. Make sure CarPlay is allowed as follows.

Step 1. Go to Settings > Screen Time and tap Content & Privacy Restrictions.

Step 2. Tap Allowed Apps & Features, then find CarPlay.

Step 3. Toggle CarPlay on to unblock it under Screen Time restrictions.

Solution 7. Ensure Siri Is Turned on

Siri is a key communication channel for CarPlay, especially when it comes to hands-free navigation and calls. Since CarPlay relies on Siri for voice commands and interaction, disabling Siri can cause CarPlay to stop working. Here's how to activate "Hey Siri" on your iPhone.

Step 1. Run Settings and go to the Siri part.

Step 2. Select Talk to Siri, then choose "Siri" or "Hey Siri".

Solution 8. Turn Off Airplane Mode

Airplane Mode disables all wireless communications on your iPhone, including the signals required for both wireless and wired CarPlay. Even if you've re-enabled WiFi or Bluetooth manually, some connection dependencies might still be blocked. Turning off Airplane Mode can allow CarPlay to communicate freely with your car. Here's how to.

Option 1. Enter the Control Center and then tap the Plane icon to disable the Airplane mode.

Option 2. Enter Settings and then toggle off the Airplane Mode switch.

Solution 9. Disable VPN in iPhone Settings

VPNs can interfere with how your iPhone connects to external networks and devices. Some VPN services, especially those that control or reroute all traffic, may block Apple CarPlay or delay key permissions. Disabling or removing VPN configurations can immediately restore CarPlay if the VPN was interfering with the signal or permissions.

Step 1. Fire up Settings and tap General.

Step 2. Head to VPN & Device Management and turn off VPN.

Solution 10. Update iOS and Car Infotainment System

Outdated software can prevent proper CarPlay connection. Your iPhone and car's infotainment system may need software updated to stay compatible with Apple CarPlay. Both vehicle manufacturers and Apple release firmware updates to fix compatibility issues and remove bugs.

On iPhone: Go to Settings > General > Software Update and install the latest iOS.

On Car Infotainment: Check your car manufacturer's website for firmware updates and install them if available.
