Everytime I turn my carputer off, ad come back to my car later and start it up before the window screen comes up, the brightness setting are as I left them down before turning the car off. But as soon as the windows screen comes up the monitor brightness goes down to 33 instead of what I left it on which was 99. does anyone have this problem? I have to reset it every time I get back in the car, which I hate. Is something wrong with the monitor?
