Repurposing an old Android tablet can enhance your driving experience by turning it into a DIY Android Auto head unit using the app Headunit Revived. This open-source application acts as an Android Auto receiver, allowing navigation with Google Maps and access to apps like Spotify, Facebook Messenger, and Google Calendar. Headunit Revived is compatible with Android devices updated to at least Android 4.1 and can be downloaded for a fee from the Play Store or for free via an APK from GitHub. It can also be used on older Amazon Fire tablets.
To set up Headunit Revived on your tablet, grant necessary permissions, agree to terms, and follow the Quick Setup Wizard to select screen size and orientation. The app will optimize the Android Auto layout based on your tablet's specifications. You can modify settings for UI scaling, dark mode, and screen resolution.
To connect your phone to the tablet, you can use a USB cable or a wireless connection. For a wired connection, connect the phone via USB, select the appropriate USB settings, and launch Headunit Revived. For a wireless connection, enable Wi-Fi Direct on both devices, set the connection strategy in the app, and use the Wi-Fi Helper app on your phone to connect.
Once connected, Android Auto will load on the tablet, allowing access to navigation and music apps. You can switch between navigation apps and exit Android Auto by unplugging the phone or using the Wireless Helper app. Various mounting options are available for securing the tablet in your vehicle.
