Another iPhone connection question

[Woozle]

We have a 2006 2WD EX. We have an iPhone 3G, as well as an iPhone 3GS, both of which will be upgraded in the next year. My husband enjoys listening to podcasts, but in the car, he is having to just use the iPhone's external speaker. I would love to get him something for Father's Day that would allow him to listen through the Pilot's speakers. My head is swimming with the possibilities: USA-Spec PA15-HON2? Music Link 2.0 (though I think that I understand that iPhone is not supported with music link)? Honda installed MP3 player? My preference would be to not disable the 6 disc CD changer. Even though we hardly ever use it, I don't want to change too much about what he already loves about our Pilot. I just want to enhance it. What is my best option for capability and sound quality? My husband is not especially handy, so my only fear with an aftermarket product is that it might sit in a box uninstalled. Any quick help and suggestions would be appreciated. The Father's Day clock is ticking!
Thank you!!

I'd just try one of those FM transmitters

Not particularly cheap, but they get the job done, especially if it's just for podcasts
