Apple Tests Parked-Only Video and Third-Party Chatbots in CarPlay With iOS 26.4

Overview

• Developer and public betas show video casting to the dashboard only when the vehicle is parked, alongside a new Apple TV app.
• Casting uses AirPlay from iPhone, limiting support to vehicles whose infotainment systems offer Wi‑Fi and integrate AirPlay.
• CarPlay relies on the connected iPhone’s accelerometer to detect motion and disables playback once the car moves.
• iOS 26.4 also surfaces third-party voice chatbots such as ChatGPT, Gemini, and Claude as CarPlay apps, with Siri remaining the system assistant.
• A public release is expected in late March or early April, though Apple could change timing or features before rollout.
