I'm very much interested in upgrading my old PIONEER system to the new AVIC-8100NEX. I was wondering if anyone out there can speak about the quality of the noise cancellation microphone when making phone calls. My old system had all kinds of echo problems and wanted to make sure that before I made the investment into the AVIC-8100NEX that these problems are cleared up. I also wanted to know about the quality of the Voice Recognition as well. Any help with your experience in this product would be appreciated.
