Android tablets can function as Android Auto displays

Older Android tablets can be repurposed to provide a large-screen interface for Android Auto in vehicles that lack factory-installed systems. By using the Open Headunit application, available on the Google Play Store, a tablet can serve as a display while a smartphone performs the primary processing tasks.

This solution allows drivers to access apps like Google Maps, Waze, and Spotify on a larger screen without needing to purchase expensive new head units or vehicles. While the application is a paid product on the Play Store, its source code is available for free on GitHub for users with advanced technical knowledge.
