I have no idea..I figured it was a software program that generated/displayed the safety lines..I'm asking for a friend who has a 2013 Prius Prime. She has everything, solar, moon roof, HUD, etc..but has a pet peeve abt not having those "lines" on the backup display..
All I know about this is what I've seen on Amazon while looking to upgrade my own backup camera. (By the way, the one thing I do know is that the OEM Gen 3 camera uses 6v, and aftermarket cameras need 12v, so upgrading a Gen 3 camera needs extra wiring for power) Pyle lists their camera as having a "built-in distance scale" NOAUKA's camera has a wire you can clip to turn their distance scale off (thumbnail pictures all the way on the left, 4th one down) Even if the Gen 4 does have the distance lines generated by the display, I've got to think that you'd have a much, much easier time upgrading the camera than you would trying to get the Gen 4 display into the Gen 3.
