Yeah, you can hook up an iPod using the RCA aux-in feature. Though there might also be an adaptor that allows you to control and charge your iPod through the stereo cd-changer port.
There a cable that best buy carries called a Deson (spell check) ice link that will change your changer controls into a ipod controller.Cable there runs 199.99.You can also do the new blue tooth setup in your car for 179.99.
