I have had same problem. Recently, I solved the issue. The Ringer & Alerts “Change with Buttons” is the key, but not the same with both of my cars.
2010 GMC Terrains It must be turned ON
2020 GMC Acadia It must be turned OFF
It is still a pain going back and forth between the two cars, but at least I know what is happening.
Trouble didn’t start until I got the 2020. This is not a surprise from GM as the can have a similar dash design in two cars, but the buttons do not do the same things. To many people working on similar projects and each wants to do it their own way with no regard to consistency. I am sure they are not the only ones. Maybe change with buttons needs an automatic option, besides on or off.
