What does geography have to do with Android Auto? If you want to know which cars have it I can be a little helpful because I bought a new car a couple of weeks ago (in Nashua NH, I live in MA). I limited my search to cars that had Android Auto which is a pretty small list at the moment, basically 2017 models. I bought a Chevy Volt which is an extended range electric. The other car that was on my short list was the Audi A4. Chevy has AA on a lot of cars, Chrysler doesn't have it yet and Ford is doing their own thing with Sync which they claim is compatible but I wouldn't trust it. Honda has it on the Accord but not on the Acuras. Cadillac didn't have it a month ago when I test drove one, but I think they've just rolled out a software update that enables it. Mercedes doesn't have it yet. Audi has it on the A4 but not on the larger cars, the A6 and A8 will get in next year.
