I recently replaced my OEM head unit with a Pioneer AVIC Z3 and no longer have a need for my aux in adapter. This unit plugs into the CD charger input on the back of your OEM head unit and provides two RCA inputs. Cables are available at you local electronics store to give you a 3.5mm headphone jack style input for use with an ipod, zune, laptop etc. If you have an existing CD changer, it can be plugged into this unit as well. Fits 2003-2006, maybe 07-09 as well but check to make sure. I don't think this will work with the JBL units
This unit does not provide iPod control, only audio in. I paid $75 for this just a few months ago. I will sell for $50 SHIPPED.
