Project Completed
 

I expected a bunch or harness connectors that I saw from another post and was relieved to see only one on my 05 - X5.

I actually opted not to install the Aux input plate in the glove box, but rather pig-tailed a connector that I run out of the seam below the cup holders and up to my ProClip holder for my Blackberry curve. Did the same for the USB power cord too. Much cleaner.

I am so happy to unleash the music from my NAS server to the BB Curve. Thanks guys!
