My 2016 Mercedes GLA was supposed to have support for Android Auto but the car arrived without it. Mercedes was working on the update for over a year now, and just few days ago I received an official reply from Mercedes Benz customer service saying that the technical department won't release such update, it was cancelled. It sucks to have such a modern car without support for it - and my partner's tiny volkswagen Polo supports both android auto and apple car play.
