Android Auto and Android Automotive sound similar but serve different purposes. Android Auto mirrors your Android phone onto a compatible car display, offering navigation, music, messaging, and supported apps via USB or wirelessly. It depends on your phone for functionality and works with various vehicle systems, similar to Apple CarPlay.

In contrast, Android Automotive OS (AAOS) runs directly on the vehicle’s hardware, providing a built-in platform for infotainment, instrument displays, climate controls, EV information, and other vehicle functions without needing a phone. AAOS is open‑source, while Google Built‑in offers native Google services (Maps, Play, Assistant) as a separate optional package. Some manufacturers, like Rivian, use AAOS alone, while others, such as Polestar, combine Google Built‑in with AAOS and retain compatibility with Android Auto and Apple CarPlay.

The Polestar 2, launched in 2020, was the first production car to feature Android Automotive OS.
