Looking at each pic in comparison to the other, one clearly says AA while the other looks like a it is mirroring your phone display. Mirroring displays items that you would expect to see on your phone like your favorites menu, the icons along the side that would appear pinned to the bottom of your phone screen like, Phone Maps Spotify Messages, and in your photo, shows a display like you're in an app. Are you connected the same way in each photo, USB/Wirelessly? Are you using navigation for both pics? If you are not using the same connection method or the same apps it could account for the display difference.
If it is a case of connection type, whether connecting as AA or mirroring, and this is happening randomly here are some steps you can try to cause it to connect as AA every time.
Steps to Fix Connection Issues:
- Reset Connections: On your phone, go to Settings > Connected devices > Connection preferences > Android Auto > Previously connected cars. Tap the menu (three dots) and select "Forget all cars".
- Remove Vehicle Pairings: In your phone's Bluetooth settings, forget your car. In the car’s infotainment system, delete your phone from the list of saved devices.
- Re-pair Carefully: Pair your phone and car again. Ensure you allow all permissions (Location, Bluetooth, Nearby Devices) when prompted.
- Set Connection Priority: In your car's settings, find "Device Connections" or "Phone Projection," and ensure Android Auto is prioritized over screen mirroring/media transfer.
- Check Background Activity: Ensure the Android Auto app is not set to "sleep" or restricted in your phone's battery settings.
- Use USB First: If using wireless, establish a solid, consistent connection with a high-quality USB cable first.
