I have a 2010 Audi A3 S-Line with the Audi Concert II+ 2-DIN head unit recently installed to replace the old head unit of the same model and the standard fitted AUX input near the cigarette lighter. (See attached images)
It doesn't seem to me like the AUX input is working.
I'm not sure if there is a cryptic way to change source, if so what would this be?
With it being a standard fitted AUX input I would have assumed this would be pre-wired into the wire cluster therefore would just be plug and play?
If anyone could shed any light on this that would be helpful.
Cheers! :)
