iPod lead for standard Renault headunit

Sorry to bring this thread back to life, just exactly what I need, however I also have a parrot system connected to the audio too, can someone point out exactly where the green plug from:

plugs into the back of the head unit. Don't want to buy it then realise it's being used by the parrot system.
Picture below is of the rear of my head unit, is the plug for the green connector free?

IIRC you take out the yellow one and the green one clips to it and goes back in so its at the side of yellow one.
 
i got mine today and plugged the green clip next to the yellow one and it doesnt seem to play am i doing something wrong?
 
You need to do something to bring AUX up, did you not get any instructions with the lead?

I did but not sure were they are now.
