I am currently looking to get an aux input in my 2006 A3 so I can play music from my phone or ipod (I don't want the ipod specific hookup, rather an aux) and was wondering if anyone knew exactly what I would need. I have tha audi concert stereo with a single disc cd player, no cd changer or anything. I have found some aux connectors online bu there are so many different ones that I want to be sure to get what's right..
