If your iPhone charges but wired CarPlay won’t connect, park the car and unlock the phone. Plug it directly into the car’s CarPlay USB port using a cable that carries data. If the CarPlay icon appears on the car’s screen, select it. Try one change at a time so you can tell what made the difference.
Apple released iOS 27.2.1 on November 9. One driver reported that wired CarPlay stopped working after the update and later said it was working again. If yours still won’t start, begin with the USB connection and then check the iPhone settings. See Apple’s release information and the driver’s follow-up on MacRumors.
Check the USB cable and port first
- Unlock the iPhone and reconnect it. Unplug the cable, unlock the phone, and plug it back in. If the iPhone or car asks you to allow the connection, follow the prompt while parked.
- Use the port meant for CarPlay. Look for a CarPlay or smartphone icon beside the USB port. If your car has several ports, check the manual for the one that supports wired CarPlay.
- Try a different cable that carries data. Use a cable that fits both ends and has worked for data transfer. Connect the phone directly to the car’s USB port. Remove any hub, adapter, or wireless CarPlay dongle for this test.
- Select CarPlay on the car’s display. Some systems wait for you to choose CarPlay on the screen. If it still doesn’t appear, try another USB port that the manual lists for CarPlay.
Apple recommends trying a different cable and port and notes that some combinations of cables and adapters can interrupt a wired connection. The Apple CarPlay troubleshooting guide has the connection checks. If this is the first time you’ve connected that car, start with our CarPlay setup guide.
Choose the next check based on what you see
| What you see | What to check next |
|---|---|
| The iPhone charges and the car shows no CarPlay icon. | Try a known data cable in the CarPlay USB port with the iPhone unlocked. |
| The car shows a CarPlay icon but the app won’t open. | Select the icon. If it still won’t start, check Siri and Screen Time, then restart both devices. |
| CarPlay launches, then drops when the cable moves. | Try a different cable and another supported port if available. If the connection is still loose, ask the car or phone maker to check the port. |
| Another iPhone works with the same cable and port. | Check your iPhone’s settings and set up the CarPlay connection again. |
Check Siri, Screen Time, and the saved car
- Make sure Siri is on. Open Settings on the iPhone and search for Siri. Check that it’s enabled.
- Check whether Screen Time allows CarPlay. Go to Settings → Screen Time → Content & Privacy Restrictions. If restrictions are on, open the list of allowed apps and make sure CarPlay is enabled.
- Restart the iPhone and car. After both restart, unlock the iPhone and reconnect the cable. Check for any available iOS update under Settings → General → Software Update.
- Set up the car again if the connection still fails. On the iPhone, go to Settings → General → CarPlay, choose the car, and tap Forget This Car. Reconnect and follow the setup prompts.
If you also use wireless CarPlay, check that Bluetooth and Wi-Fi are on. In the iPhone’s Wi-Fi settings, select the CarPlay network and make sure Auto-Join is on. Apple explains both connection types in its CarPlay setup instructions.
If the wired connection still fails
If you can, try a second compatible iPhone with the same data cable and port, or try your iPhone in another car with working wired CarPlay. If the problem follows the car, check the manual for an infotainment firmware update or ask the vehicle or stereo maker. If it follows the iPhone, tell Apple Support the iOS version, car model, and which cable and port you tested.
If CarPlay opens and only the sound is missing, check the selected audio source. Our guide covers what to try when the radio stops playing after CarPlay connects.
FAQs
Can a cable charge an iPhone without starting CarPlay?
Yes. Charging shows that power is reaching the phone. Wired CarPlay also needs a USB data connection. Try a cable that you know carries data in the car’s CarPlay port.
Which USB port should I try first?
Use the port your car manual identifies for wired CarPlay. It may be marked with a CarPlay or smartphone icon. If more than one port supports CarPlay, try another one with the same cable.
Why try again with the iPhone unlocked?
An iPhone may need to be unlocked before it recognizes a wired accessory. Unplug it, unlock it, and reconnect it. Apple explains this behavior in its wired accessories guide.
What does Forget This Car do?
It removes that car’s saved CarPlay connection on your iPhone. You’ll need to set up the connection again the next time you plug in.
