Google is set to launch the Gemini update for Android Auto, enhancing hands-free functionality for drivers. The update will feature different experiences based on vehicle compatibility, with around 250 million cars supporting Android Auto and about 50 models equipped with Google built-in. Gemini allows for voice control independent of an Android smartphone, enabling tasks like adjusting climate settings through natural language commands. Vehicles with Google built-in will have access to the Google Play Store and integrated car manuals. Gemini will also include offline capabilities and streamline trip planning via voice commands. Most features will be available across all vehicles with Android Auto, with a rollout expected in the coming months. The pre-release version showed improved reliability over the previous Google Assistant.
