A friend of mine has a 2007 Sportback with a concert 2 (single din) head unit.
I did my search but couldn`t find what i was looking for
Is it possible to add a AUX-in port to the Single din stereo?
I got a Concert 2+ myself and AUX was already installed when i bought the car.
I know what parts are needed, i just need to know if it is possible or not.
Looking at the Concert 2 diagram i couldn`t see any ports described as AUX in (+,-,GND)
