Pilly, sorry for my late reply. This IceLink does not even need to fiddle with the radio and center vents: as far as I know, even if you don't have the CD changer, you *should* have its wiring already there. I will stand correct if someone knows better !
To check if you have the wiring, go to the boot, lift up (from its bottom) the carpet on the firewall and you should see the back of the SatNav unit, if you have one. There you should find the two connectors for the 6CD changer, a 3-pin and a 6-pin plug.
