Mirror monitor, 5.8 inches. This is a vintage item, over 15 years old, but I was using it normally until I removed it. My children have grown up and don't watch videos in the back seat as much anymore, so I took it out. It's an old item, but I've been using it until now. There may be some scratches from use, but I think it's in good condition. Everything in the photos is included. No returns or exchanges, please.
