We’re excited to introduce a whole new way to use Android Auto: right on your phone screen! This update allows anyone with an Android phone (running 5.0 or later) to use a driver friendly interface to access the key stuff you need on the road ― directions, music, communications ― without the distraction of things that aren't essential while driving.

So all you need would be an AUX cord (sorry Apple/Moto) and the android auto app will display UI same as android auto display mount. The new update will be rolling in the upcoming weeks (where android auto is available). But pretty sure apk file would allow installation to any region
