Android Auto runs from your smartphone and updates via the Google Play Store like any other app. While it typically updates automatically over Wi-Fi, you can manually check for updates by searching "Android Auto" in the Play Store. If you see an Update button, tap it; if only Uninstall appears, you're current. Ensure auto-updates are enabled via the three-dot menu. Devices need Android 9.0 (2018) or newer for the latest features like Gemini and widget support.

If updates fail or glitches persist, reset the app via Settings > Apps > See all apps > Android Auto > Storage and cache > Clear storage. This clears preferences but not data in Maps or Spotify. Reconnect to your car to test.

As a last resort, uninstall updates from the same app menu (three-dot > Uninstall updates) to revert to the factory version. If that's more stable, disable auto-updates temporarily. Otherwise, update again for a fresh install. Most issues resolve with these steps, ensuring access to Google's latest interface overhauls and assistant upgrades.
