This might not be new news, but I just found it. It appears that Toyota, and other car manufacturers are working on a Linux based infotainment system. I don't know if it is going to be backward compatible with the systems already in our cars. You can read the article here: Toyota owners to get Linux system instead of Apple CarPlay, Android Auto. Hooray? The questions mentioned regarding the integration of phone software (Apple or Android) and this Linux software may be interesting for end users. In any event, I am still replacing my JBL system with a new head unit soon, as I want Apple CarPlay.
