Where can I get firmware updates for Carplay?

Official Website: Many manufacturers provide download links for firmware updates on their official websites. Owners will need to visit the manufacturer's support or downloads section and enter their vehicle's details (such as model, year of production, VIN, etc.) to find out if an applicable update is available.

Dealer/Authorized Service Center: Some manufacturers may require owners to take their vehicle to a dealer or authorized service center for a firmware update. This could be because the update process requires special diagnostic tools or software, or the firmware update is combined with other necessary maintenance checks.

Automatic updates: Some modern vehicles come with the ability to automatically download and install updates via Wi-Fi or built-in cellular data connection. This means firmware updates can happen wirelessly while the vehicle is parked, similar to operating system updates for smartphones or computers.

USB/SD card updates: Some manufacturers may provide a USB drive or SD card to download updates. Owners can update by downloading the update file onto a USB drive or SD card and plugging it into the appropriate port on their vehicle.

Mail-in media: In some rare cases where a car owner is unable to download the update themselves, the manufacturer may choose to send the update to the car owner on a mailed USB drive or other storage media.

Mobile Apps: Some car brands may provide update notifications and instructions through their proprietary mobile apps. Through the app, owners can get information about updates and, in some cases, initiate the update process directly.

Each Carplay manufacturer has a different update method. When updating firmware, please read the Carplay instruction manual or contact the Carplay manufacturer.

How to update Carplay?

Since CarPlay is actually powered by your iPhone, updating CarPlay doesn't require you to interact with CarPlay directly, and the update process is the same as updating iOS on your iPhone. Here are the steps to update CarPlay:

Update iOS

Make sure your iPhone is running the latest version of iOS. To update iOS, go to Settings > General > Software Update. If an update is available, you can download and install it from here.

Make sure CarPlay is compatible

If your vehicle or third-party infotainment system supports CarPlay, the iOS update should also update CarPlay functionality.

Check if your vehicle manufacturer provides information about Carplay system firmware updates. These updates are sometimes necessary to ensure compatibility with the latest version of CarPlay.

Connect using USB or wireless

Some vehicles support CarPlay over a USB connection, while others support CarPlay wirelessly. Make sure you know which connectivity method your vehicle supports and follow the appropriate connectivity steps to launch CarPlay.

Check for third-party app updates

For third-party apps that use CarPlay, make sure you have downloaded and installed all available app updates from the App Store.

Reboot the device

If you're experiencing CarPlay connection issues, try restarting your iPhone and your vehicle's infotainment system.

Once your iPhone is updated to the latest version of iOS, any improvements or new features related to CarPlay will be automatically applied. If you don't see these updates on your vehicle's display, the problem may be with your vehicle's infotainment system, in which case you may need to contact the vehicle manufacturer to learn how to update the vehicle system's firmware.
