2020 GMC Sierra 1500
Have had this truck for about two weeks or so, and am still getting used to it. Up until yesterday, I had not noted this (problem). I get home and shut down the ignition and radio is going. I understand it will and (should) keep playing while I'm still behind the wheel, but I'm expecting it to go out when I open the door.
Got out yesterday and tried it again this morning, the damn radio keeps playing after I'm out and the doors have locked and milage hours, etc. still displayed on dash.
Now I imagine after a short while it shut itself off, but why is it doing this???
