In the TV, though not part of it: replaced the malfunctioning rear view monitor. Easy fix; order new one, remove film on screen, plug in. The camera is mounted on the TT's license plate, and we have wires running under the TT, then a connector and another set routed through the truck bed, into a back door and to the front. It's all powered by the 12v outlet in the TV. Some of the pins on the monitor side of a connector broke; we decided we just need to leave all that connected. We used to remove the monitor in bigger breaks between trips.
