Yep, I've been mulling some DIY work on replacing the headlights and adding foglamps... Despite appearing bright on my garage door, the actual street visibility of the standard headlights is pretty awful on this car.

I'm not sure about 2015 Mazda 3, but I know 2016 and later cars can be upgraded to support Android Auto for a fee at the dealer (I want to say ~$500, which may or may not be worth it).

The AA upgrade is available to all Mz3 vehicles starting with the 2014 model year, since that's when they came out with the MazdaConnect system. The Mz6 is similar.

As for foglamps, I have the factory foglamps on mine and they're completely useless; I can't see them at all. Maybe it's because my xenons are so bright, but regardless, I never use them.

It should be possible for you to swap in the factory xenons if you want, though you might have to set something with ForScan to allow it to work. Not really sure about that.
