i dont know about that particular model, but what probably is a better idea is to purchase and install a new head unit with audio-input jack so you can directly wire your ipod to the head unit and speakers. something like the Aiwa CDC-X204 or CDC-X304 might do the job for you. the first goes at $80 from crutchfield.com, but the price goes up to $100 with all the installation accessories

besides, its not just adding an input jack, its upping the rms range of your head unit and you'll get improved sound quality right away, even if you stick with your stock speakers
