How to Change Wallpaper & Theme on Your Android 12 Stereo

Make your dash feel like yours. Swap wallpapers and pick the home‑screen layout in a few quick steps.

Set Your Wallpaper

1. Pick your images.
   • Save one light image for daytime and one dark image for nighttime.
   • If your display rotates, also save vertical versions.
   • Use JPEG or PNG format.
   • Match the resolution to your screen (e.g., 1920×1080).
2. Organize them on a USB drive.
   • Create a folder named wallpapers.
   • Inside, create day and night folders.
   • Within each, add a folder for your screen size (e.g., 1920x1080).
   • For rotating screens, include both 1920x1080 (landscape) and 1080x1920 (portrait).
   • Place your images in the correct spots (day images in day, night images in night).
3. Import to the stereo.
   • Plug the USB into the head unit.
   • Open the Wallpaper app.
   • Tap Import → choose your USB path → Start Copying.
   • Set your wallpaper from the imported list.

Tip: If your unit supports auto day/night, it will switch wallpapers based on lighting.

Change the Theme

Choose the home‑screen layout you like: UI1 or UI2. Try both and stick with the one that feels right.
