What is included in the pre-wiring on the 99.5 A4 1.8t? I don't see a microphone - is it hidden?

The manual makes some strange reference to Bose and cell phone speaker selection.

I was hoping to integrate a cell phone eventually - someone tell me the microphone is there, but tastefully hidden!

See the small grill next to the sunroof controls? That's the mic. Also, the left front speaker has a dual voice coil. One for the stereo, the other for the phone. There is also wiring detailsin the FAQ.

Probably not. Read the F.A.Q.'s on the subject. They give the pinouts for the stock wiring. You will probably need to fabricate some type of converter as is described in the F.A.Q.
