CD Changer Through Dice Silverline?

[BrockWed]

Hey, I'm looking to buy a DICE Silver line kit and last night when I was looking at them it shows that there is an AUX port on the back. Does this mean you can hook up a CD changer through the AUX port on the DICE module and have both iPod integration and a CD changer? I think I would have to get an aftermarket CD changer because I don't believe the stock BMW one has AUX out. Correct me if I am wrong. Also do you know of a company that makes a single disk player? I just want to be able to play a CD and I don't need a 6,8,10 disk player if there is just a single disk player option. My car has NAV. Thanks!!
