I'm trying to figure out what I need to get in order to connect an iPod to my stereo, and if it is even possible

I've a 2006 Multivan with a 6 stack CD player, vw model 2680 according to the handbook. It appears to be a factory fitted option but I can't find out any more information about it (my Google fu is failing me). I'm guessing I need to get one of the kits from a place like www.ipodcarkitdirect.co.uk or www.xcarlink.co.uk but I can't find any reference to this cd player there.

So, question is, does anyone know if it's possible to connect an iPod/iPhone to this model player? If not, any good recommendations on an alternate double din head unit?
