Search for an AUX input interface for the 7th gen or 03-07 accords, there are several to choose from. I really don't recommend one as the volume won't be as loud relative to the radio and CD volume, why I don't know just is. Your much better off with an aftermarket HU, but to each their own I guess...


EDIT: If you even read this thread one is listed, here is the picture of one taken directly from this thread. Just read abit and you'll find everything you need.
