Auto music & Ac level on phone call

Hi
My 2011 Tahoe had the nice feature when a call came in the raido would automatic lower the volume & the Air would do the same. Wonder if this can be programmed in?

Happens when you make a onstar call. Not sure about reg call?

When i used my iphone in my Tahoe it always worked. Nice feaure. Here i am always scrambling to turn down air & music.
