Android Automotive vs. Google Built-in: Two Google Car Systems, Two Different Roles

The distinction matters as automakers move away from phone mirroring systems such as Apple CarPlay and Android Auto in favor of native infotainment. Google has supported that shift with both products. General Motors has moved away from Android Auto in favor of a Google Built-in solution since 2023. Automakers describe such moves as creating a more seamless connection between a driver and their vehicle. Some customers have met the changes with anger and confusion, saying built-in systems are likely intended to open new revenue streams through subscription models or the sale of driver data rather than to improve the driving experience.

Google has become a major player in the infotainment space. Manufacturers deploy its in-car technology through Android Automotive Operating System, or AAOS, and Google Built-in. Unlike Android Auto, which projects a phone's display onto a car's dashboard, both Android Automotive and Google Built-in are independent operating systems with applications and features that run without a phone. Connecting a phone and car to the same Google account may increase compatibility, but neither system requires an Android phone. For consumers, the difference can be difficult to parse, yet it produces measurable changes in the customer experience and can have a major effect on how an infotainment system looks and operates.

Android Automotive is a full-stack software solution that car manufacturers integrate into their vehicles to operate the radio, climate control, cameras, mirrors, lighting, seat adjustments and instrument clusters. It is open source and highly customizable, allowing manufacturers to design their own in-vehicle infotainment and software systems using Google's infotainment architecture. That flexibility lets them create systems specific to their brands and drivers, add Android in-house applications and customize layouts. In some cases, drivers may not even know their infotainment system is powered by Google. Rivian, for example, declines to include Google-specific branding in its Android Automotive system even though its Rivian OS infotainment system relies on the open source architecture.

Google Built-in is a group of applications that manufacturers license to integrate into their Android Automotive systems. Debuted in 2020, it gives drivers access to applications such as Google Maps and Gemini. Manufacturers that license Google Built-in also give customers access to the Google Play Store, where they can use popular media applications including Spotify, YouTube and Google Play. Sixteen brands have access to Google Built-in, including Honda, Volvo, Chevy, Nissan, Ford, BYD and Renault. A full list is available on Google's Built-in website.

The differences between Google Built-in and Google Automotive Services may become more pronounced as Google accelerates the incorporation of advanced AI features into Google Built-in applications. Gemini is rolling out across sixteen car brands and is officially replacing Google Assistant as the infotainment system's chatbot.

The integration, billed by some proponents as Gemini at its most practical, brings a host of voice-activated AI features into the car's cockpit. The Google Maps application will incorporate real-time traffic updates, EV-tailored routing and Gemini's smart navigation. Drivers will also be able to use Gemini to check email and messages, craft playlists and order dinner. One feature touted by Google is Gemini Live, which lets drivers chat with Gemini about their destination and can tap into the car's front-facing camera. Drivers can also adjust in-car settings, access hard-to-find settings and gain insights into the car's battery or performance metrics.

Google's rollout of Gemini began earlier this summer, premiering with cars that support Android Auto before expanding to popular brands with Google Built-in such as Honda, Chevrolet and Volvo.
