I used Mazda AIO Tweaks to get Android Auto support (along with other changes) in my 2017 Mazda 3. I am pretty sure they support older/other models as well. Very easy, took about 20 minutes from downloading to updating the car.

You can't do this any more if you're stuck with the very latest infotainment firmware version. It locks out the tweaks. Even if you don't have it yet, be careful because your dealer might "helpfully" install it on there for you when you come in for service or warranty work. Once this version is installed, you can't downgrade to the older tweakable versions. Very disappointing.

In addition, if they find you've tweaked the software, they won't honor any warranty claims concerning the infotainment system.
