the turning lines come from the steering angle sensor, and that info is processed outside of a camera... the TV and nav will give you just a video input, and will need to have video processed by an external "box" to overlay those moving lines... or, use N6...
or, get yourself a bird-eye view setup, and feed all 4 cameras into the birds-eye box, and feed video from that box to TV...
