Data System Video Output Harness VHO-B64 Used in a 2014 Mercedes-Benz E250 Station Wagon S212. Used for about 1 year. It was working without any problems until removal. Everything in the photos is included. (RCA conversion adapter white x1, yellow x1 are missing) I am a layman, so I don't know the details, but I was told by the shop that installed it that it connects to the digital terrestrial tuner in the trunk, and allows you to watch TV on the rear seat's additional monitor while driving.
