Suzuki + iPod Help

[ZAT]

I have a 2003 Suzuki Aerio SX that I would like to wire my iPod to, but seem to be having no luck finding the necessary parts. I currently have an FM modulator wired in and is working OK, but would like to go direct if possible. When I was installing the modualtor I noticed that the radio had an additional jack on the back. According to my owners manual the radio can handle a CD changer, which explains the additional jack. Also according to the manual my radio is a Clarion PS2533 or PS2534, but I get no results when I search for that model unit anywhere. Anyone have and words of wisdom aside from getting a new radio installed??

Thanks.
