I have a GO600 and looking to replace it. GO Supreme 5inch looks the one, but its been a long time since I bought my 600. Does GO Supreme come with lifetime maps and camera locations? Does it automatically day/night switch and how - by ambient light levels or sunrise/set? What happens in tunnels for this device. Does it connect to my cars speaker system (2016 Kona Executive OS1)? Does it have an antiglare screen, or is this standard these days? Sure you techo peoples know so hope I hear so and thanks
