Is that really true? Some backup camera systems used to display as part of the rearview mirror. (I don't know if the size and nature of the display meets the current requirements though and, in practice, I imagine all but the lowest end vehicles do use a screen for at least some entertainment functions. Big volume knobs are probably mostly a lost cause.)
Yes, but the ones in the mirror are too small. The big, wide angle backup cameras are wonderful. So much better than the limited mirror. They see a much wider area and below the bumper.
I just said they need a screen. And to display video you need a screen somewhere, so yeah it's true. And the government does mandate all new cars to have a backup camera monitoring system.
