The pic’s a bit small, but the SuperVisor from PD3 is basically a flip down screen that goes where your sun visor normally does in your car. A camera records what’s going on out the back and the LCD screen relays the info back to you. And there was me thinking that’s what a rearview mirror is for. Unlike a rearview mirror, however, this also plays MP3s which are fed to the visor via the two SD/MMC slots. It will record voice notes as well. I’m assuming that the pics are fed to you the correct way round, which has surely got to be a bit confusing after using a mirror? Presumably there’s some advantage to the SuperVisor that I haven’t spotted yet.
