help locating panoramic roof control module

[ModestW12]

Hi everyone, I was hoping someone knew the location of the panoramic roof control module in a 2005 X5 4.8is (10/04 build date)?

Tried advanced search (plus hour of google) and no luck tracking down the location.

I recently bought the 4.8is to replace my dearly missed 2006 X5 4.4i that was totaled by another car running a red. I bought the 4.8is with the pano roof not working. When I press the switch, there is zero movement or sound from any part of it (glass or shade). I checked the pano roof fuse (58 IIRC) and it's good. Carly diagnostic app/adapter shows a no communication with the pano controller error (don't have the error specifics at work with me but I'll update when I have a chance). All other systems are fine.

So I bought a pano controller from the local salvage yard but I can't seem to find where it's located in the car.

The controller label contains the following info:
MDS K-Bus
6 995 925
Siemens 5WK11491
04015300604

Would greatly appreciate any help, even if it's ideas on where in the car to look or links to recommended BMW service documentations sources that would have the answer.
