could be base on the limits imposed by the video codec that they use to stream to the HMD this page https://www.mathieupassenaud.fr/build-your-own-android-auto-... talks about H264 but they also need USB data also for the touch controls

Thanks for posting this.

> Android auto is just a remote screen. Nothing is generated by the car display. A H264 video stream is generated by the Android App on the smartphone.

So ... the car really just needs to implement h264 streaming to be compatible? So there's exactly nothing special about bringing an app to Auto (in theory)?
