Not really. That's an immediate noise cancellation function, which only works (a) with headphones and (b) by recording the outside noise and adding its inverse to the sound being played.

i don't mean necessarily doing active NC. i was more curious about doing an initial tune with the car at idle or while driving on the road as a way to compensate for the average. is there any value in doing something like that? maybe even just to tune the EQ profile of the car.

some cars/car stereos have had auto eq'ing with an active microphone in the past, I have to assume they still do.

my 2007 has active eq'ing to counteract road noise, and a different eq setting when the top is up, based on a switch.

it's a Bose stereo.

No, as the frequencies involved will vary based on speed, engine RPM, and what seat you're sitting in.
