Lightly used backup camera. The camera charges via usb. The monitor plugs into auxiliary plug for power. I replaced the lithium battery in the camera for which came in a two pack, so there is a spare battery for future. The camera is magnetic mount so you can mount anywhere on your tailgate, etc. Worked well for me but my newer vehicles had the built in system for backup. The newer versions are selling for around $260. I am asking $75 for this one and is a reasonable price. local pickup and cash only.
