I am surprised even android auto worked with that if its the original ami port with a usb female dongle.No idea what colour the USB is, but it's the original MIB1 glovebox USB port so I'm 99.9% sure it doesn't support Apple Carplay (given all the forum posts on the issue and requirement to change the USB port when going to MIB2 head units - something I ignored being on Android platform which works fine wired).
You need the harness and the new plug.
