iPod interface

Has anyone found an interface that will allow direct connection of an iPod to the audo system of the Azera? In my old car, I have an 'ipod2car' device that fakes out the stereo into thinking it's talking to a 6-CD changer; you unplug the 6-CD changer and plug in this device. Works great, perfect audio (I have no interest in CDs any more, when I can have my entire collection on one device).  I could not find any device that would claim to work with the Azera (tried over at www.crutchfield.com, and also www.diceelectronics.com ), no luck. 
 
I'm not interested in the FM Modulator option. 
 
Thanks!
