Mazda 3 (2015) - upgrade infotainment for Android Auto

[iamcoda]

Hello,

Wondering if anyone replaced their Mazda Connect system with Mazda (or with 3rd-party)? I tried using AA via AIO Tweaks but it's quite buggy, and the USB charging is really slow - it doesn't charge as fast as the  phone consumes the battery. 

I enquired with Mazda on the upgrade price but haven't heard back yet. I'm curious if anyone upgraded their system?

Thanks
