JADO G100+ 12-inch Adjustable front and rear camera angles Rear camera zoom function Front camera 4K Rear camera 2K Used item (main unit, instruction manual has tears) Unused (accessories, etc.) I purchased a 12-inch model about a year ago, but the slight interference with the sun visor bothered me, so I bought an 11-inch model with the same manufacturer and specifications, and I am now selling this one. The accessories are the same, so there are no problems at all. I have confirmed all functions by inserting the rear camera, GPS antenna, and SD card. SD card (64GB) formatted Simple initial settings completed *Set to 50Hz, please change it if you are in western Japan. In my opinion, JADO products have a high level of completion. I recommend the rear camera zoom function; it's easy to gauge the distance to the vehicle behind you. Also, both the front and rear cameras have adjustable angles (up and down), which is convenient. Thank you.
