Wired backup camera with a 7" screen in the TV. Used for backing up and monitoring traffic behind me for safer lane changes. Camera is near the bumper.
Esky 7-Inch TFT LCD Color Monitor Car Backup Rear View Camera System (Night Vision, Side Camera)Here's a pic of my mounting arrangement. The cable is zip-tied under the TT and terminates with a connector at the tongue. The cable from the monitor is wired to a jack near the 7-pin connector. When I connect the TT cable, I connect the camera at the same time.
