Repurposing Tablets for Android Auto
Android Auto, designed for in-car infotainment systems, can be extended beyond vehicles. Users can install a third-party receiver application on a spare Android tablet or phone, allowing it to act as the display for Android Auto. This method utilizes the phone's processing power, making it suitable for older tablets that may struggle with modern applications.
Setup Requirements
To implement this setup, users need an Android phone running Android 11 or newer, a secondary Android tablet or phone to serve as the display, and a data-capable USB cable. Android Auto is integrated into compatible phones, so the primary requirement is installing a receiver app on the second device.
Two notable third-party receiver apps are Open Headunit (formerly Headunit Revived), available for $3.99, and Headunit Reloaded, priced at $4.99. Open Headunit supports Android 5.0 or newer on the receiving device, though USB compatibility can vary with older hardware.
Connection Process
The wired setup involves connecting the tablet to the phone via a USB cable, potentially using an OTG adapter. Users must select Android Auto in their phone's USB options if prompted. On the tablet, opening the receiver app, tapping 'USB', granting necessary permissions, and selecting the phone from the device list will initiate the connection. Any subsequent prompts on the phone also need approval.
Self-Mode Option
Both Open Headunit and Headunit Reloaded offer a 'Self-Mode' that allows Android Auto to run on the same device, eliminating the need for a separate phone connection. However, this mode requires the device to have its own functional Android Auto installation, which may not be present on older tablets. The developer of Open Headunit notes that Android Auto 17.4 and later versions might require specific head unit startup procedures.

A new app, PhoneAuto, is in development to bring Android Auto back to phone screens, a feature Google removed in 2019. The app uses developer functionality to run Android Auto directly on a smartphone, providing an alternative to in-car displays.
Android Auto, typically used in vehicles, can be run on an Android tablet or phone using a third-party receiver app. This allows users to repurpose old tablets as Android Auto displays for desk or kitchen use, or as an in-car display without a built-in system.
