Hi. I purchased 2020 used mazda 3. The Bluetooth connection works well on music but the Bluetooth can’t support android auto. I’ve connected my phone using USB but both of the front and between the seat USB ports don’t recognize the phone.

It seems like the ports are working - my phone is charging. Even if I change the phone connection mode to file transfer/android auto, it is only being charged. When I go to the entertainment source list, USB ports are grey and inactivated while it still charges my phone. I’m using the android cable and the same cable worked fine on my rental car.

I’ve deleted the other Android auto connection, reinstalled the app, deleted the Bluetooth connection but the USB android auto still doesn’t seem to work. Anyone has the similar issue? How did you solve it?
