There is a way to do it - it takes some fiddling around in the various settings (systems and volume settings, I think?). But there is a way to lower your ringtone volume so that when you get a call, it doesn't blast through your speaker system, although you have to turn up the volume a little bit after the call comes in.
Sorry guys, I wish I could articulate how to do it, but honestly, I did it while messing around with settings in a Target parking lot waiting for my wife and kids to finish up a shopping trip. But it is possible.
Driving a 2022 Autograph, if that helps. No clue if it works with a package like the lux, which I think has a different head unit.
