Picked up Bronco from dealer. I was told that the SCV is set completely different than any other vehicle that I've ever owned. Here is what the tech told me.
Set SCV to 'Off'. Drive Bronco on a high-speed road with your volume set to the highest that you would listen to. At this speed and volume, select the SCV setting you want. Now as you slow down, the volume will decrease.
I did this and I could hear it working. He mentioned that it works in reverse of what you think. It takes the speed and volume at the time of the setting and lowers the volume from there. So, I went out on the interstate at 80 MPH with the volume set to 20 and selected the high SCV setting. So far so good. I'll report back later after I have more time to check out how it works.
