Update: I followed
@YoAdrian ‘s unpinning steps, and I was finally able to get the 4 + pins removed from the harness, AND Zero feedback noise! Thanks again
@YoAdrian!
Stereo sounds great! I honestly can’t tell any difference in road noise in the cab, with it deactivated. I drove to work with the ANC harness unplugged (stereo off), for a test. Half way to work, I pulled over and plugged it back in. Didn’t notice any changes in noise in the cab. In my experience, the ANC is no good. Food for thought..
