Connecting iPod to concert radio


Registered User
I have a 2008 A4.
It has the concert radio, no AMI in the glove box and no aux connector in the arm rest.
I know there is a lot of threads on how to attach iPod connections and different methods To do it but I can't work out which one I need.
Can someone please advise on what is best to buy. I would like connection for my iPhone to be operated by radio controls and hands free for calls, if possible work my phone from the radio controls. Also if possible Bluetooth my music rather than having to plug in every time.
