Android Auto 15.4 (build 15.4.6540) is now rolling out globally, bringing a refreshed interface, improved Google Maps tools, Pixel 10 connection fixes, and groundwork for Gemini AI integration. The update was first spotted in early October 2025 and is now reaching more cars via Google’s phased deployment model.
How Android Auto 15.4 Reaches Devices
Google’s rollouts always start slow. Android Auto 15.4 began in early October 2025 as a beta before expanding through stable waves later in the month.
The stable build (15.4.6540) is now live and gradually arriving through the Play Store. Some users report receiving it automatically, while others can manually install via APKMirror to skip the wait.
What this really means is that Google fine-tuned under-the-hood stability longer than usual. Some Pixel 10 users saw black-screen or disconnection bugs with version 15.3—issues the new build appears to resolve.
Let’s break down exactly what features Google has slipped under the hood.
What’s New in Android Auto 15.4?
Enhanced Interface and Customization
Android Auto 15.4 introduces a more cohesive visual design, syncing accent colors with your phone’s wallpaper for a cleaner, less distracting dashboard. AndroidSage reports redesigned icons and subtle animation tweaks that make the system feel smoother and more unified.
Upgraded Features for Google Pixel Users
Pixel owners can expect exclusive tools such as Call Notes and Call Screen, which let drivers review conversation details and manage calls safely through the infotainment display. Google confirmed these Pixel-specific features will arrive by late 2025, integrated with the upcoming Gemini AI voice system.
The Shift to Gemini AI Assistant
Google is quietly preparing to replace Google Assistant with Gemini AI, a more advanced conversational system built on the same multimodal model powering Android and Workspace. Demonstrated earlier with Mercedes-Benz vehicles, Gemini brings faster responses, contextual awareness, and natural-speech control for maps, messages, and media.
Many drivers ask: Will Gemini fully replace Google Assistant inside cars?
Google says the rollout will be phased, beginning in select regions through 2026.

Additional Improvements and Changes
Google Maps Enhancements: Google Maps for Android Auto now allows more drivers to report hazards and accidents directly from 7- and 8-inch screens—a feature previously reserved for larger displays. The pinned hazard system, first tested in 2019 on phones, is now available for in-car reporting.
Fixes and Compatibility Improvements: Pixel 10 and other new Android phones benefit from improved USB and wireless connections, addressing the reboot bug and delayed connection issue. This build stabilizes pairing reliability across vehicles using Android 12 and later.
So, why should you care about this new version? Let’s break down the direct improvements to your daily drive.
How Android Auto 15.4 Improves Your Driving Experience
Smarter visuals: adaptive colors and modern iconography enhance readability.
AI prep: Gemini AI groundwork improves voice-based interaction.
Pixel-first upgrades: call summaries and smarter call screens coming soon.
Navigation boost: incident reporting now on smaller screens.
Fewer glitches: stable connection fixes for Pixel 10 and other new phones.
If you haven’t received the update yet, you can sideload the APK safely or wait for automatic deployment. Google’s staggered rollout ensures stability across regions and vehicle systems.
Why It Matters
Android Auto 15.4 shows Google’s long-term vision: merge AI-driven intelligence with safer, distraction-free design. This release might seem incremental, but it lays the foundation for Gemini-powered driving—where the assistant predicts your needs, manages routes dynamically, and communicates naturally.
As automakers expand Google built-in systems, Android Auto 15.4 will act as the bridge between smartphones and embedded dashboards. For everyday users, it means fewer taps, better voice control, and a more seamless experience on the road.
