What I am trying to get
CD changer connector working (So that I can plug in a grom unit)
Retain the steering wheel controls
Head unit must fit into single slot (not a double height unit)
What I have
I have a chorus tape unit (car made in 2000) - Pinout is http://www.tehnomagazin.com/Auto-radio-car-connector/Audi-Car-Radio-Wiring-Connector.htm
I connected the aux unit to the cd changer connector, then realised that the CC/CD button just switches the head unit to tape mode
So, is there
a) A way of making the CC/CD button trigger the cd changer (unlikely i guess)
B) Does someone know which audi cd head unit is pin compatible, and meets what I am trying to get
