Mazda owner here. Still waiting for they mythical CarPlay/Android auto update that will supposedly come to 2014 and up models. They are using the same infotainment system in 2017 models so I'm still holding out hope.
I'm sure you know that there is an unofficial Android Auto installation available on certain Mazda forums. Unfortunately, they still haven't managed to fix a serious issue with Bluetooth calling.
In addition, if they find you've tweaked the software, they won't honor any warranty claims concerning the infotainment system.
