I was using this as a backup camera for a trailer. I used it for about 3 weeks. The reason for selling is that I'm selling it because I'm switching vehicles. The backup camera in photos 2-6, and the two 7-meter wiring sets are new and unused. (These were purchased separately from the set. The retail price was 4955 yen.) The backup camera in photos 8 and 9 has been used for 3 weeks. The camera lens is fine, but there are scratches and dirt around the camera, so please refer to the photos. Items in photos 14-16 were purchased separately. I will include those as well. The monitor in photos 18-19 has a protective film on the LCD screen.
