Do JVC Car audio decks use a special Aux input cable?

Is it a universal aux input? Are all aux inputs the same style? I want to get an aux input to 3.5mm to hook up an ipod. Will the 15dollar version at futureshop work?

Thanks
yes is special, or no it isnt special?
I want to go Aux Input to 3.5mm without any RCA's peferably.
