Is that a micorphone in the overhead?

That is where the microphone is located and I believe it is for both NAV and Bluetooth. I dont think the mic will be there unless you got the package with Bluetooth or NAV

 

My guess is that, on non-bluetooth models, the microphone isn't present. by removing the microphone, they cut down their costs a little without removing any functionality the normal user would see (with no bluetooth, you don't need a microphone for any factory items in the car).

the plastic cover for that overhead section is probably standard, as Evan suggested. It's much cheaper for them to produce one mold for the piece and use it regardless of the presence or absence of a microphone. functionally it's no different from a mold with a solid piece there, and asthetically it doesn't add or subtract much.

 

According to the service manual, the harness is not wired up there (there's a '*3 - navigation unit only' next to those connectors)

If you need reference information:
It's connector O3, Overhead J/B (Page 52.)
It's supposed to terminate to the MFD (Page 330) (where can view plugs into)
Hmm.. that connector doesn't exist without nav, so the upper one probably dosen't exist either..
If you take it apart and see a connector, look for shielded red and green wires, and a brown wire. (3 pin connector)

I'm hoping that it is wired, otherwise, it's going to be a fun wire run.. I want to do the same thing with my CarPC so that I can do that whole voice recognition thing. If I have the time, this is going to have a custom echo canceller. Gotta love them mips!

I've wanted to use built in microphone, at least those locations. That'd be really cool.
