European X5 Ice>Link Plus install: HELP PLEASE

[apetrov1x5]

Hi, I have been trying for two days to connect my Ipod. The car is a 10.2004 European X5 (British) with Nav, TV, CD changer. after searching for the radio module in the boot as advised by the vendor (www.ipodcarkitdirect.co.uk), I called my local dealer and he said that if the module is not in the boot, then it is in the front. so i removed the screen, and no, there are 2 small plugs, not the quare plug which came with the ipod.

my question is: where can the radio module be? I tend to think that it should be in the trunk, but can anyone explain please how to find it? there are a lot of wires and connections there, so please help me out here.
