The 2 selector knobs are usually in the center of the dashboard (most vehicles)..1st press the left knob to activate the system...
use the knob on the right to select the appropriate rattle cancellation frequency. Then go back to the left knob and adjust the actual amount of cancellation you prefer.. Presto! No bad noise...only good sounds..

Use a high-end noise canceler for best results...
I like the way you think. I splurged and added navigation to my noise cancelling device.
