When my 2021 Sierra is in motion, some of the infotainment system capabilities are grayed out. Does anyone know how to defeat that?
In some of my other vehicles I had to clip a wire or add a ground so that you could use all of the functions while driving.
Is it possible to change the DC Power Outlet (old cigarette lighter outlet) from constant on to switched on/off? I use this port for my radar detector and it stays on when the truck is off. I am afraid it will drain down the battery over time.
