I just installed a 930bt in my 2003 Sierra. I have the microphone clipped to the sun visor. I can hear the people on the other end of the call clearly. They are complaining about too much back ground noise. What are my options? There really is not a better place to put the mic.

Does the CD-MC20 Auto-EQ help at all with the mic picking up background noise?

I have the same issue, I tried to mount my mic in a number of difference places and still sucks, I added a foam cover on the mic and it did help, But it still far from being up to par.
