I am "privileged" enough to have a rare 2005 X5 4.4 with no NAV and true "Digital" DSP requiring me to purchase the additional DSP module to make the system Icelink system work.

Since I do not have a wiring diagram for my X5, can anyone recommend a wire to tap into in the rear of the X5 (preferably around where the CD Changer would go) for a "Switched 12V Source" for the DSP Module??

Thanks in advance for your help!!
