Audi 2011 Q5 hook up

[mprusin]

New to site - was wondering if anyone had information on 2011 Q5's. I have a phatbox that i originally had in a 2004 VW toureg then bought a connection to convert to BMW when i switched cars. I need to find out if there is a cd changer cable anywhere in the Audi i could connect the phatbox too. Does anyone know of a good Audi lead or where a cable is in the car i cold connect too?
