how does next generation of CarPlay work?

The next generation of CarPlay offers a deeply integrated and customizable experience that combines the best features of your car with the familiar interaction patterns of your iPhone. Here are some key aspects of how it works:

1. Wireless Experience: The next generation of CarPlay is a wireless-only experience, ensuring seamless reconnection and stability during drives (Meet the next generation of CarPlay architecture).

2. Customizable Design System: It features a powerful new design system that is built to be deeply customizable, adapting to any vehicle's drivetrain, feature set, and configuration. This includes support for various screen sizes and configurations, from single to multiple screens (Say hello to the next generation of CarPlay design system).

3. Vehicle State Integration: The system relies on the vehicle to provide up-to-date state information, which is reflected in the UI. This ensures that the data is used only where needed and often does not leave the vehicle, protecting user privacy (Meet the next generation of CarPlay architecture).

4. Local UI Rendering: The local UI is rendered directly on the vehicle's system using an OpenGL-based renderer, which allows for low latency and high responsiveness to car signals. This local rendering ensures that the UI starts instantaneously, even before the iPhone is detected or reconnected (Meet the next generation of CarPlay architecture).

5. Dynamic Content and Custom Features: The system supports dynamic content that combines vehicle information with CarPlay features. Automaker apps can be used to create rich, custom UIs and experiences, including specialized settings, alerts, and notifications (Say hello to the next generation of CarPlay design system).

6. Flexible Layout System: The layout system is flexible and can adapt to the hardware configuration and design preferences of the vehicle, allowing for a co-branded experience that integrates seamlessly with the car's native features (Say hello to the next generation of CarPlay design system).
