A quick and reliable guide to diagnosing the most common CarPlay connection failures.
Like most features on your iPhone, CarPlay should be simple to use once set up. Unfortunately, as with any technology, problems can arise that prevent CarPlay from working properly. Once accustomed to the conveniences of Apple’s automatic software, you may feel stuck in the past when you instead have to use your phone’s screen to listen to music and maps. And that doesn’t even take into account security concerns.
Maybe you can’t get CarPlay to work for the first time, it stopped working after a period of normal use, or it keeps disconnecting suddenly. These issues often have the same root causes, so troubleshooting should resolve them. Unless the problem is with the cable you’re using for CarPlay, you won’t have to spend any money either.
You don’t need to be an auto technician or iPhone expert to apply these fixes, so even novice users should soon be able to enjoy their favorite music and navigation streamed to the car’s screen.
Start with simple CarPlay troubleshooting steps
It’s always wise to check simple things before spending time on advanced troubleshooting. Start by restarting your phone, then turn off your car and restart it. This ensures that no temporary issues prevent a good connection. Depending on your car, CarPlay may not open automatically when you connect your iPhone. Find it on your car’s default infotainment screen and tap to open it.
If this is your first time trying to use CarPlay, check Apple’s CarPlay vehicle listing to confirm that your car is compatible with this feature. Every iPhone from the iPhone 5 onwards works with CarPlay, so unless you’re using an iPhone 4s or earlier, device compatibility isn’t the issue. Apple also publishes a list of countries where CarPlay works, but as long as your car (or aftermarket stereo) supports it, it doesn’t matter where you are.
Also make sure Siri is enabled on your iPhone, as this is necessary for CarPlay to work. Start by heading towards Settings > Apple Intelligence and Siri (or just Siri if your phone does not support Apple Intelligence). There, press Talk to Siri (Or Speak and type with Siri with Apple Intelligence enabled). Make sure the top option is not set to Disabledand activate it Press the side button for Siri cursor if it is disabled. Finally, update your iPhone to the latest version of iOS. Although CarPlay does not require the latest version of iOS to work, software updates may fix temporary issues that may be causing your problem.
Allow CarPlay while your phone is locked
By default, after connecting your iPhone to your car, you must unlock your phone once per trip so the two can communicate. It’s an annoying step to take every time you start a trip, and when the icon doesn’t appear on your car’s screen, you might think CarPlay isn’t working when it’s actually just locked. If you don’t want to do this step every time, there is a simple solution.
Open Settings on your iPhone, then go to General > CarPlay. Tap the name of your vehicle, then activate the Allow CarPlay when locked cursor (if it is not already done). Now you don’t need to use Face ID or your PIN to let CarPlay start talking to your phone; it will appear as soon as you connect it with a cable or wireless.
With this setting enabled, someone with access to your phone and car could use CarPlay to make calls, send messages, and access other data on your device without having your password. In most cases, you can leave it on for your own vehicle, but consider turning it off when you’re driving a car that isn’t yours.
Troubleshoot the cable or wireless connection
If you are using CarPlay with a USB cable, try connecting to another USB port in your car (if there is one). If there are several, it’s worth checking your car’s manual to see if any of them are intended for CarPlay/Android Auto use. Next, try a new USB cable. I’ve had to replace the USB cable I use for CarPlay several times; Between the extreme temperatures inside a vehicle and the twisting, they don’t last forever.
Likewise, if you need to place your cable in a perfect position to keep the CarPlay connection stable, it’s time to replace it. When you do this, make sure you use a cable marked for data transfer, not just charging. Unlike the best iPhone accessories, cheap cables often don’t have the ability to move data and don’t work with CarPlay. Avoid using adapters with CarPlay; a direct connection is more likely to work. When replacing the cable, check the USB ports on your phone and car for dust and gently clean any buildup you see.
If you connect to CarPlay wirelessly (perhaps using a third-party adapter), open Settings on your phone and make sure Bluetooth and Wi-Fi are turned on, as wireless CarPlay connections rely on both. In the Wi-Fi menu, press the I icon next to your car name and make sure Join automatically is enabled so you don’t have to log in manually every time.
Confirm that CarPlay is not disabled
Your phone’s parental controls may completely block certain features from working. If CarPlay still doesn’t work at this point, go back to Settings and access Screen Time > Content and Privacy Restrictions. If you have set up a password to lock screen time restrictions, you will need to enter it here.
If the restrictions slider is enabled, choose Authorized applications and features and make sure the cursor for CarPlay is green (meaning it is enabled). If this slider was already disabled, that’s not your problem.
Likewise, in your car settings, look in the options menu for a Relationships Or Devices section. There, check if CarPlay is disabled or your phone is disconnected. This will depend on your car, but it’s worth checking in case the problem is buried in its menus. Take a look at your vehicle’s manual to see which options apply.
Re-pair your car and phone
Then you need to remove the CarPlay connection between the two devices and configure it again. To do this, go back to Settings > General > CarPlay on your iPhone and select your vehicle. Before resetting, capture your app layout and widgets so you can easily configure them after resetting. Faucet Applications and a screenshot if necessary, then repeat for Widgets. This will also reset the options available in CarPlay Settings panel, but you cannot check them if CarPlay is not working.
Once ready, choose Forget this car. If you are able to update the firmware of your car stereo unit, try doing so. Then you will need to pair your phone again. For a wired connection, connect a high-quality USB cable to your phone and your car’s USB port. If your car supports wireless CarPlay, open the device pairing menu on your car’s screen (which you can often do by pressing and holding the voice control button on the steering wheel). On your phone, go to Settings > General > CarPlay and select your car when it appears.
If you see the CarPlay logo on your vehicle’s screen after re-pairing, you should be in the clear. Tap it, go through the initial setup steps again, then customize CarPlay like you had before: Make sure to install some of the best free CarPlay apps, like SpotHero and TuneIn. If all else fails, you can try resetting your head unit to factory settings. This should be a last resort, as you will lose all existing settings. Check if your car allows you to export your configuration to a USB key; otherwise, you can take photos of each option to remember how everything was set up. If resetting fails to get CarPlay working, it’s time to contact the car manufacturer and/or Apple.
