[Fixed] CarPlay not working after iOS 17.5 update?

Apple CarPlay offers a safe and seamless way to access iOS apps on your car’s infotainment. With Siri onboard, you can make calls, send texts, and use maps handsfree. However, sometimes CarPlay simply stops working. It could be due to connectivity issues, wrong setup, or other reasons.

Besides, many users are reportedly facing this issue after updating to iOS 17.5. Let us take a look at how to fix common Apple CarPlay issues.

Why is Apple CarPlay not working?

CarPlay is a well-thought-out iPhone feature that can be useful while you’re driving. But sometimes, a single or a combination of issues can prevent Apple CarPlay from working for you. Some common reasons why this issue might occur include the following:

  • Your car doesn’t support CarPlay, or it only works via a USB cable.
  • Issues related to the car’s USB port or the cable you are using.
  • Pairing issues between your iPhone and car’s infotainment system.
  • Misconfigurations or unpatched software glitches in iOS 17.5

How to fix Apple Carplay not working after iOS 17.5 update

1. Precursory checks

  • Ensure both your car and iPhone supports CarPlay.
  • If your vehicle doesn’t support CarPlay, consider upgrading to a third-party ICE (In-Car Entertainment).
  • Download and install the latest iOS update.
  • Check if your car’s infotainment is updated to the latest firmware; for help, visit the manufacturer’s website.
  • Check for conflicting devices. Disconnect other wireless devices on your iPhone. See if CarPlay works now.
  • Ensure adequate power supply to the car’s infotainment.
  • Restart iPhone and see if it makes any difference.

2. Ensure CarPlay isn’t restricted in Screen Time settings

A major reason why Apple CarPlay might not be working for you could be because you’ve disabled it using Screen Time on your iPhone. You may follow the steps below to ensure that CarPlay is allowed in Screen Time.

  1. Open the Settings app on your iPhone.
  2. Go to Screen TimeContent & Privacy Restrictions.
  3. Select Allowed apps → Toggle on CarPlay.

3. Check USB cable and USB port

If you’re unable to use CarPlay over a wired connection, you might want to check the USB cable you’re using. Often, damaged or non-Apple USB-C or Lightning cables can prevent CarPlay from working correctly in your car.

To ensure that the cable you’re using isn’t causing the issue, you should replace it with another cable and see if you can access CarPlay again.

In case you’re unable to use CarPlay even after replacing the USB cable, check of you’re using the correct USB port. While your car might have several USB ports for charging, only a few ports on the car support both data transfer and charging.

In most cases, a USB port that supports data transfers features a different logo than the one that only supports power. But, If you’re unsure about it, you can always refer to your car’s manual to locate the correct USB port.

4. Check if iPhone is connected correctly

While using CarPlay via a USB cable is straightforward, this is not the case when using wireless CarPlay. If you want to use wireless CarPlay, you must:

  1. Pair your iPhone to the car through Bluetooth.
  2. Connect to a CarPlay Wi-Fi network created by your car.
  3. Press and hold the voice command button on your steering wheel.
  4. Navigate to Settings → GeneralCarPlay.

  6. Then tap the CarPlay icon on your car’s display if needed.

  1. Open the Settings app on your iPhone.
  2. Scroll down and select Siri & Search.
  3. Toggle on Press Side Button for Siri and Allow Siri When Locked.
  4. Tap Listen for → Select any option other than Off.

6. Restart your iPhone and car

If the previous solutions didn’t help you, simply restarting the iPhone and your car might do the trick. Restarting the iPhone will help you eliminate any temporary software glitches that can cause CarPlay to malfunction.

Meanwhile, restarting your car will help you ensure that it re-registers the USB/Bluetooth connection that is needed for CarPlay to work correctly.

7. Unpair and set up CarPlay again

In case you’re still unable to use CarPlay in your car, it’s recommended that you unpair and set up CarPlay again. This should help you eliminate any technical issues that could prevent CarPlay from working for you.

  1. Navigate to Settings → General → CarPlay.
  2. Select your connected car → Tap Forget This CarForget.

  2. Connect your iPhone to your car either wirelessly or via a USB cable.
  3. Navigate to Settings → GeneralCarPlay.
  4. Select your car → Tap Use CarPlay to accept the connection.

8. Check for software updates

Pesky glitches or bugs in iOS 17.5 can also cause CarPlay to malfunction. To ensure that this isn’t the case with your iPhone, you should regularly check for software updates and install them as soon as they become available.

  1. Navigate to Settings → General → Software Update.
  2. Tap Update Now if an update is available.

Apart from updating the software on your iPhone, you may also refer to your car’s user manual or contact the manufacturer to see if it’s possible to install a firmware update on your car’s infotainment system.

Sometimes, a technical glitch in your car’s infotainment system can also prevent CarPlay from working for you. The only way you can resolve such issues is to reset your car’s infotainment system to its default settings by referring to your car’s user manual or by contacting the manufacturer.

10. Reset all content and settings on iPhone

If resetting your car’s infotainment system didn’t help, your best option will be to perform a factory reset on your iPhone. This will erase all the personal data stored on your iPhone and revert all settings to their default state.

  1. Navigate to Settings → General → Transfer or Reset iPhone.
  2. Choose Erase All Content and Settings.
