Was it ever a problem to get the kind of phone SoC or camera chips you'd need for a backup camera if you were willing to pay an extra $20? I thought the issue was more specialized things. And you need one gigabyte of ram or less.

A gigabyte!?

You shouldn’t need any dedicated RAM. A decent microcontroller should be able to handle transcoding the output from the camera to the display and provide infotainment software that talks to the CANbus or Ethernet.

And the bare minimum is probably just a camera and a display.

Even buffering a full HD frame would only require a few megabytes.

Pretty sure the law doesn’t require an electron app running a VLM (yet) that would justify anything approaching gigabytes of RAM.
