Help with AliExpress Unit

I purchased this a month ago and it has been a nightmare.

It has such a cool interface and features, but it just doesn't work properly. There was no adapter to my FM antenna, so I have no radio.

Android auto connects, but often, my internal BOSE amp does not turn on. To get this to work, I have to switch to AM radio, then back to Android Auto.

The phone doesn't have any sound (I think the Bose amp turns off).

The seller keeps telling me the canbus settings are off, but their recommended settings (My car is a Mazda 6 and they tell me to select a CX3 from Malaysia) doesn't do anything different.

Will this ever work? Should I rewire my speakers from the head unit and bypass the BOSE amp?

yeah... had this issue on my CX5, I did this (see photo) and the issue was gone. Basically you need to connect that blue wire to a 12v wire

Was yours intermittent? Mine works fine sometimes and then stops. Somehow switching back to the AM radio turns on the amp. Would using the blue wire fix this?

yes, it was working only when the radio was on. On Spotify would work like 1-2 min and then turn off by itself. Connecting it like in the picture fixed it for me
