Instead of Android Auto, Apple CarPlay, or some “custom OS”, all I want is a standard video input that will be displayed on a screen.<p>To make this even better, route the touch input of the screen back to the device, in some simple way (for example, as a mouse position, not sure of any touch protocols).<p>Any software has a pretty good chance of getting deprecated or irrelevant during the lifetime of a car. Just think of what is still actively supported in the mobile world from 10 years ago. My 2013 car doesn’t have Android Auto or CarPlay, but has built-in “apps” for Stitcher and Pandora, which I never used. The bluetooth connection still works, but is really flaky with newer iPhone (a 2013 Android worked exceptionally well, however).
