100% functional. for those not familiar, this unit allows you to control an ipod through your headunit via the ai-net connection. sold the headunit, so i no longer need this. $50 shipped via paypal. thanks
no you need the 420 box with this cord to connect to your ipod . it lets you control the ipods music thru the headunit instead of controlling it thru your ipod.that cord on the left will hook up to an alpine headunit with out the 420 box whats the box do?
