## What it is
Open Headunit is an Android app that turns an Android tablet, phone, or aftermarket head unit into an Android Auto receiver. It is a revived and modernized fork of the original mikereidis/headunit project, supporting wired USB and wireless connections with high-resolution video decoding.

## Use cases
- turn my android tablet into an android auto head unit
- run android auto on an aftermarket android head unit
- connect my phone to a car display wirelessly with android auto
- display android auto on a 4k tablet in my car
- use android auto without buying a new car stereo
- automatically launch android auto when bluetooth connects in the car

## When to choose
- you have an Android-based tablet or head unit and want Android Auto projection on it
- you need wired USB or wireless Android Auto receiver functionality without root
- you want customization like keymapping, DPI scaling, portrait mode, or HUD flip

## When to avoid
- you need Apple CarPlay support
- you rely on wireless Android Auto with AA 17.4+ without running the headunit server on the phone
- you need a certified, manufacturer-supported Android Auto experience
