That grey piece of foam in the bottom is not the BT unit. I can take a picture of mine later, but it sits right at the bottom, below the DVD bracket and is separate from it.

It says BMW Telematics on it or something like that, with all the numbers on the top.

Does the SOS button in your headliner actually have the button? The black plastic piece is just the cover and opens to reveal a separate button. I have that too if you want a picture.
