iOS 26.4 Beta: Code hints at CarPlay video feature with Apple TV

Apple has released the first beta version of iOS 26.4 to developers. The update contains new code references that indicate a forthcoming video playback feature for CarPlay. As shown on the Apple Developer page for CarPlay, the iPhone manufacturer intends to enable video streaming via AirPlay to the vehicle display connected to CarPlay in the future – Apple TV is also to be supported.

Apple first mentioned the video feature at WWDC 2025 and announced it on the developer page. With iOS 26.4, the implementation is becoming more concrete: according to the Apple news blog MacRumors, specific code fragments related to the integration of the Apple TV app have appeared in the current beta version. There are indications of explanations during first use, notifications, and interactions with the TV app. A message in the code suggests that users must complete their Apple TV subscription via the iPhone while the vehicle is parked.

Only when the vehicle is parked

For safety reasons, video playback should only be possible when the vehicle is parked. Apple relies on integration with vehicle systems that the respective automobile manufacturer must implement. The iPhone uses GPS and motion sensors to automatically stop playback as soon as the vehicle starts moving. Apple aims to prevent distractions while driving.

The technical implementation is done via AirPlay streaming from the iPhone to the CarPlay display. Automobile manufacturers must integrate support for CarPlay with AirPlay video separately; participation in the MFi program is recommended. The feature is intended to be compatible with both classic CarPlay and CarPlay Ultra. It is currently unknown which vehicle manufacturers will specifically support the feature.

Login and subscription required

To use Apple TV in CarPlay, users must be logged in via their iPhone and possess a corresponding subscription. The code also contains privacy notices displayed during the setup process. Login and subscription must be completed while the vehicle is parked.

In addition to the video feature, iOS 26.4 brings other innovations for CarPlay, including support for AI apps like ChatGPT. Apple is also testing end-to-end encryption for RCS messages in the beta, with availability depending on the respective provider.

The final version of iOS 26.4 is expected to be released in spring 2026, likely in March or April. A public beta phase is expected to follow in the coming weeks.
