Is my stereo compatable with this 6-disc cd changer?

I have an Alpine iDA-x305 head unit installed. It is a digital media receiver, meaning it does not play cds, only radio, usb drive, and through iPods. I have an old Alpine CHA-S634 6-disc cd changer and was wondering if it was compatible with my head unit so that I could also play cds. Thanks

Yeah thats prolly the easiest way to find out. But now that I scrolled down the page for the head unit link, I think it will work. It mentions Flexible System Building Options and one on the list is cd changer. Now the only problem is, I need to find the little plastic thing that holds the actual cds that you insert into the changer.
