An old Android tablet can run a car interface at home

An old Android tablet can display Android Auto at home using a third-party receiver app, repurposing the car interface for a desk or kitchen counter. The setup may help keep maps, music and messaging visible while limiting the temptation to browse other phone apps, though it is an unofficial workaround.

The wired method requires an Android 11 or newer phone, a second Android device and a data-capable USB cable. Open Headunit costs $3.99 and supports receiving devices running Android 5.0 or later; Headunit Reloaded costs $4.99, and both offer a Self-Mode option with extra requirements. Wireless connections are possible but take more setup, and the phone must stay connected; maps can dominate the screen, messages may be visible to others, and Google’s official instructions do not cover home use.
