When I bought my car used from private listing, the guy already had a wire running through that opening under the radio/AC. Phone can charge when car is off and able to play music. Im asking here because the part that goes into my iPhone now broke a little and it will only play from my passenger speaker. It's not my speakers because regular radio works fine. I have no idea where this wire goes so I don't know if I have to bring it to Acura or something for a new one. The guy had a pamplet in the glovebox about it being Honda/Acura way of it's AUX.

It's the USA Spec I think and just the bottom of the wire that goes into ipod is kind of broke so I just need a new wire. Is there anyone I can just get a new wire? I see the whole Spec kit is like 150.
