My pop up display is broken, the back (the part that covers the dashboard when the screen is down) broke away. I need a head unit replacement. Since the display is multi-purpose, when I replace it with an aftermarket unit, I expect I will lose some native features like the car computer displays. It appears from posts I have seen that the radio can be replaced on the front of the dash and that I have a lot of options. But what about the popup display on the dashboard?
