I have a Dension Icelink active cradle kit for my 2003 X5 and wondered if it can be wired into the 6 disc cd in the trunk? The car has the standard BMW business cassette with 6 cd in the trunk and the BMW hifi speaker system. No satnav.

Any help would be appreciated as i was originally going to wire direct to the back of the headunit but the grub screw underneath the volume knob is broken and I cannot remove the head unit so need to find another way around this problem.
