2016 Silverado radio has constant power

[Tommy Sutherland]

Ok I've got a 2016 Silverado that has a parasitic draw. I've ran through the parasitic draw test to find the radio fuse kills the draw. The center display backlight stays on after the accessory power  shuts down and everything goes to sleep I'm a very experienced technician but to 5 don't have access to wiring diagrams so my question is where does the radio fuse get it's power is it switched because anytime u push the button the radio turns on with no key in the ignition I believe the radio having constant power is a symptom of the draw but not the primary source so my question is where is the root power supplied to the radio from is it bcm ??
