If yall really think that pioneer was solely responsible for yall needing a new radio to support Android Auto, then you have a fair amount of misplaced rage. Much like Apple did to pioneer and other radio manufacturers, it is a safe bet that Google has a set requirement on internal hardware to run there system. Look around, it's the same reason that no one has been able to add carplay to older units with out doing an oddball hack, (which honestly I don't put a ton of faith in actually working fluidly like Carplay does on the current NEX's)
