I have the same Rexing as 16ACE27. I contacted Rexing just after purchasing it for my Camaro SS because I wanted to buy an additional dash/cigarette lighter power cable in order to also use it inside my coach. I didn't want to have to pull the power cable out each time of the Camaro and use it inside the coach on trips without buying a second camera. Rexing asked me to send them a photo of my install in my Camaro and they sent me an additional power cable for free. I was so surprised with their customer service. It works great and is easy to use. I have been using it for several years now.
