I have an ipod and it does work well with the adapter/charger that I bought at Best Buy however, when you unplug itl, the car stereo is louder. I called Mercedes about the stereo that came in the clk430's and they said that they haven't made the kits yet for them that you can plug the ipod directly into it. I have a friend that has a 2006 330i that has it built in and the ipod sounds awesome!!
