Google looks like it's working on some Android Auto features. One of them brings Gemini Live to cars and another adds support for "local media." A look at Android Auto's code shows a new string directly referencing a codename associated with Gemini and the ability to "start conversation." But it doesn't look like it's live yet. There are also added assets like "star" used for Gemini spotted in this version of Android Auto.
9to5Google reports Google is working on supporting car radio control through Android Auto. There are clues that it will support adding and removing "Favorite" stations through an app on Android Auto. And there are hints it will support "local media" from your car, too. There are also new icons for local media playback and radio but these haven't gone live yet. We have no idea if and when Google will roll out these features. But we're keeping our eye on it.
