Just bought 2019 Mitsubishi Mirage G4 sedan, trying to figure out all the technology in these new cars, it's challenging. I cannot get the backup camera to work when I put it in reverse it doesn't pop up on the screen like it's supposed to and when I go to it manually on the screen I get nothing but a black screen. Is it possible the camera doesn't work or am I doing something wrong? I also cannot get the steering wheel controls to work the stereo etc. The cruise control on the right side works fine but none of the controls on the left side work at all. Manuel says to hold down mode button and it will work but when I hold it down nothing happens.???
