It's the Telematics Control Unit. Apparently it handles all communications-related features, including BMW Assist and Bluetooth. I have a different stereo set-up in my X3, but the dead TCU also killed 2 buttons on my steering wheel - the one that does the last number re-dial and triggers the voice command system, and the radio/telephone button that switches the stereo between audio and phone controls.
Hope that helps somehow and that you get it fixed soon!
