iOS 26.4 Beta Lets You Stream Apple TV Shows on Your CarPlay Screen While Parked

Apple CarPlay with iOS 26.4 Apple TV streaming feature

Apple's CarPlay is about to get a major entertainment upgrade. The latest iOS 26.4 beta contains references to a new feature called "AirPlay Video in the car" — which lets users stream Apple TV shows and movies directly from their iPhone to their car's CarPlay display. The feature was first announced at WWDC 2025 but has yet to ship publicly. Its appearance in this beta suggests it's getting closer.

What Is "AirPlay Video in the Car"?

The feature gives Apple TV a dedicated app space within CarPlay, similar to how music apps work today. Instead of basic screen mirroring, users get a proper streaming interface — browse, select, and play content from Apple TV directly on the car's infotainment screen using AirPlay.

  • Stream Apple TV+ shows and movies on your car screen
  • Full Apple TV app interface inside CarPlay
  • Uses AirPlay from iPhone to car display
  • Only available when the vehicle is parked (safety restriction)

Safety First: Parked Vehicles Only

Due to safety regulations, the streaming feature will only activate when the car is not in motion. Apple has built this limitation directly into the feature — so don't expect to catch episodes on the highway.

Car Manufacturers Need to Upgrade

There's an important catch: vehicle manufacturers will need to upgrade their infotainment systems to support both CarPlay and the new AirPlay video integration. This means not every car will automatically receive the capability after the iOS update releases. Newer vehicles with updated head units are more likely to be compatible.

Voice Chat Apps in CarPlay

The iOS 26.4 beta also introduces support for voice-based conversational apps within CarPlay — bringing AI chat assistants into the car. However, third-party AI apps will face restrictions: Apple is expected to prevent them from being activated with a wake word like "Hey Siri." Users will likely need to manually launch the app before interacting with it.

When Will It Release?

iOS 26.4 is currently in developer beta. Apple hasn't announced a public release date, but its inclusion of these features suggests the company is building toward a release in the coming weeks or months. The iOS 26.4 developer documentation confirms Apple is laying the groundwork for enhanced in-car entertainment through CarPlay.

The Bottom Line

Turning your parked car into a cinema is genuinely useful — think waiting for someone, sitting in a charging station, or just a quiet parking lot. The catch is real though: your car manufacturer has to support it. If you drive a newer vehicle with modern CarPlay hardware, keep an eye on iOS 26.4.
