I just installed exactly what you describe. While I'm still really POed with Rear View Saftey I installed the RVS-CW-CAM. It's wireless, 7" monitor, has a really good picture and you can install from 1 to 4 camera's. I must also say do not expect ANYTHING in the way of instructions, or support. I talked at length with two different "customer service" people neither having a clue about the camera. It was only after I requested instructions for returning it that I got a call from someone that knew everything about it and convinced me to give it a try. It's not HD but a really good pic with NO interference.
