## What it is
OkcarOS is an open-source Android 13-based ROM (built on LineageOS) that lets an Android smartphone act as a CarPlay device, streaming audio, video, and touch data to a car's head unit. It includes kernel-level emulation of an iPhone for IAP communication plus an Android app implementing the CarPlay protocol.

## Use cases
- use an Android phone with a CarPlay-only car head unit
- mirror audio and video from Android to in-car entertainment at 60fps
- send lossless PCM audio to a car stereo over CarPlay protocol
- build a custom automotive Android ROM from LineageOS
- reverse-engineer the CarPlay protocol on Android

## When to choose
- your car head unit only supports CarPlay but you have an Android phone
- you want a fast-connecting, high-resolution CarPlay-like experience from Android
- you want to study or extend an open-source CarPlay protocol implementation

## When to avoid
- you need ongoing maintenance, updates, or community support - the maintainer has abandoned the project and is trying to sell it
- you want a no-flash software-only solution - it requires flashing a full ROM onto a supported phone
- your device is not on the supported devices list
