You should be able to most likely get a FM modulated kit for it.. but then you're going to lose some of the quality. The way a FM modulated kit works is you'd have your IPOD hooked up to it and the FM modulator will be set to a frequency, the FM modulator goes in line with your antenna wire in the back of your headunit. To listen to the signal that is going through the modulator (in this case your IPOD) you'd tune your radio to that station (said station set on the modulator).
It's a very easy concept... but not the best sound quality.
