There is no software. I'm not entirely sure you understand what it is you're after.Can you send me the link for the software? I do not want to buy a usb hub since the car came with it. Do you have the usb hub with your car?
I have a CX-3 2019 Grand Touring but I know I do not have Android Auto, they only gave me a navigation card instead of Android Auto.
I am not sure if I have the phone icon next to the usb port.
- Android Auto (or Apple CarPlay) requires both an app on your phone and USB ports (the hub) that support it (Or a hack, which on our cars requires disassembling the dash, wires, serial ports... a lot of work, instructions can be found at https://mazdatweaks.com/, and I have no further information nor have I tried that).
- If the USB ports on your car do not have a phone icon then they do not support android auto natively, they are only designed for media files. You must install a USB hub that does.
- If the USB ports on your have that icon, then you already have android auto. Download it on your phone, connect it with a USB cord, and you'll be done.
- The navigation SD card has no bearing on Android Auto whatsoever.
