What I'm imagining is something similar to Android Auto / Chromecast / Samsung's smart TV "evolution kit", using a connector in like HDbaseT (everything-over-ethernet) or USB C 3.1 (both of these connector solutions even offer up to 100W power transfer and arbitary data streams). Basically an RPi3 / RPi Zero with a single connector and a number of well defined interfaces for audio, video, talking to car systems, networking, etc... The possibility to swap I/O devices would be nice too, so you can integrate stuff like Soli (Google ATAP) when modules for that shows up. And I want that same thing for smart TV:s too. Ideally both of those could use the exact same standard too!
