70.00.100 already has AA (non AIO version) built into it. Once it senses the GENUINE Mazda USB/SD Card Hub, AA should be enabled.

I would recommend NOT installing .367 since it disables the serial port and prevents further modding.
I'm sorry, I'm pretty ignorant, in what ways will I be limited if the serial port is disabled? As far as modding goes, I'm not interested in modding it any further. I just assumed since .367 is the latest update that it would improve speed/quality of life.

OK, coming back to your question... as you already have 70.00.100 installed (capable of original Android Auto), it does not matter, if you put in the new parts/hardware first or do the update to .367. You can go both ways.
