Reverse camera in 2019 Honda City is blurry

If the camera is physically working and giving you an image – albeit a fuzzy one – the first thing to try is to physically clean the lens of the camera. Road grime, water, dust and even spider webs can all block the camera’s lens and make for a blurry image. A soft, clean cloth and some clean water might be enough to restore clarity.

If not, then you may have a problem with moisture actually inside the lens. This will require the camera to be disassembled to some degree to clean the inside of the lens.
