I am having difficulty finding out if you can adjust the brightness of my infotainment screen on my new 2019 3LT convertible. First of all is it possible and how do you do it? Secondly, does this system have HD radio capabilities and how do you turn that system on? I have tried to find all of this in the manuals and I also contacted Chevy directly ( they were not much help). Before I make the trip to my dealer I thought I would ask the experts on this forum since most of you are more knowledgeable about our cars than Chevy is. I just pick up the car last Saturday ...Thanks in advance
