Apple CarPlay is a secure and hands-free way to access apps on your iPhone while driving. With Apple CarPlay, you can use your phone to make calls, send text messages, and listen to music.

You might find it really annoying to sit in your car for ages, trying to figure out why your CarPlay is not working. But you don't have to worry overmuch. In this article, we'll look at what causes the issue of Apple CarPlay not working and how to resolve it.

Part 1. Why is My CarPlay Not Working After Updating to iOS 17/16?

There can be several reasons behind the malfunction of Apple CarPlay. These are the most common causes for the issue:

  • iPhone Model: CarPlay is not supported on iPhone models before the iPhone 6 series. If you have an older iPhone, it won't be compatible with CarPlay.
  • Car Incompatibility: Some cars may not have built-in support for CarPlay, or they might have limited compatibility with certain iPhone models. It's best to check with the car manufacturer or refer to the car's documentation to confirm if CarPlay is supported.
  • Regional Limitations: CarPlay may not be available in certain regions. So, if you are in a location where CarPlay is not supported, you won't be able to use it.
  • Siri is Switched Off: CarPlay relies on Siri for hands-free operation. If Siri is disabled on your iPhone, CarPlay may not work. Ensure that Siri is enabled in your iPhone's settings.
  • Bugs in CarPlay or iOS Version: Occasionally, software bugs can cause CarPlay to malfunction. Ensure that both your iPhone's iOS version and CarPlay's software are up to date to minimize potential issues.
  • Improper iPhone Connectivity: If there are connection problems between your iPhone and the car's infotainment system via USB cables, it can lead to CarPlay connectivity issues. Ensure that the cable is in good condition and correctly connected.
