Android Automotive OS is more than that, as it is the software platform that is installed in the vehicle itself and allows automakers to integrate it with infotainment, instrument displays, climate controls, EV information and other vehicle functions rather than just providing an interface from a connected phone.
So, is Google built-in the same as Android Automotive?
AAOS is open source, while Google built-in relies on a separately licensed collection of Google Automotive Services. That can provide a car with native Google Maps, Google Play and Google's voice assistant, without the driver's phone. Google treats those services as a separate, optional package rather than part of AAOS itself.
That difference is important when you're reading a spec sheet. For instance, Rivian builds its own software experience on top of AAOS and doesn't offer Android Auto or CarPlay projection.
Polestar demonstrates how flexible things can be. It can have Google built-in in its AAOS-based cars and still be compatible with Android Auto and Apple CarPlay, so it's not a case of either/or. In 2020, the Polestar 2 was the first production car to feature Android Automotive OS.
