I've got a base model 06 Civic and the one feature that I'm really wanting is a proper aux in. I've tried FM transmitters but they never seem clear enough, and I don't want to put in a whole new head unit. The stock unit that is in the car has a CD/AUX button, so I thought it might be an easy task to put it in. Does anyone know of some official or just simple way to get an aux in port with the original stereo?

Thanks
