Well in this case, think of your Accord as a giant set of external speakers for your iPod, same as if you were getting one of those gizmos from BestBuy to plug it into and listen to music, except that it also takes you places and costs more in insurance.
So the "connection" is then going to be only as good as the sound performance of the speakers in your car.
Personally, I don't want a "part" (like a CD player) built into my car that doesn't work. Wel....except for the optional voice-activated self-destruct sequence in mine, but I finally decided to pull the fuse out on that one. Probably don't need it until gas goes back under $.99/gallon.
