Android Auto language tied to phone? I have a Nexus 6P and just got a car with android auto, i use my phone and most of my things with English language (i'm used to English for tech) even tho i live in a Spanish speaking country.

Now heres the question, is there a way to set Android Auto to Spanish for example without changing the entire phone setting? Other people than me might want to use the head unit and would have to use English.

And then here's another interesting thing, when using the TTS feature to read messages, obviously its impossible to understand anything when reading Spanish with an English voice but what happens if i have messages in both Spanish and English, wouldn't it be nice to have it auto detect the language and use the appropriate TTS system regardless of the phone language?
For future reference: What worked for me was setting the search &amp; voice language inside the Google App to German. Voice commands / TTS is now German while the UI is still English (my prefered way).
