IPod Lead in glovebox?

[GTI8v]

Hi all
I've found this lead in the glovebox,

it doesn't work with an Iphone as I've tried pluging one in, lead is connected to something as the phone gave a message say it didn't support the device so I'm guessing it's for an Ipod.
Once I've found an ipod to test, what do I select on the CD player to test if it works?

Apologies for picture not being very clear... it's like the lead in this post...

Thanks, I never thought to press the CD button when I was testing the lead with the phone.
Will try to find an Ipod to test before I buy one.

Press cd button twice fast
I use my old iPhone 3gs on mine and works fine
If you create 6 play lists within the phone it displays as list of cds 1-6 and each cd number is a play list

Well I tried it today with a borrowed Ipod and it worked, pressed the CD button twice and it showed the external CD player.
Thanks for the advice and now to find a cheap Ipod.
