Try this mic! 84 31 6 938 762 Far superior to the old one. Better noise cancellation, better gain.

A friend of mine's wife was an exec at Visteon prior to her departure for bigger and better. I have talked to a number of her friends about this stuff, and they are all about voice quality. One of the main reasons for the DSP upgrades in the new ULFs and the Mic changes were to address exactly what you are experiencing.

Also a crucial configuration of the mic is with the ARROW pointing towards the front of the car. The mic is mechanically designed to get the greatest gain with the arrow facing forward. The arrow is embossed on the mic.
