I’ve got a 2010 a3 with Audi concert. I bought a Bluetooth module to fit the back of the head unit to act as a CD changer, but works via bluetooth. I had to remove the 12 pin blue adapter which was located where the white adapter is now (as pictured), next to the green adapter to fit the bluetooth, but everything seems to work as normal. Does anyone know what it’s for and is it ok to have unplugged it? Thanks for any help in advance!!! (Please ask for anymore pictures if need be!)
