Mine went out on my '04 Rx330 about three months ago. I not sure if anything I was doing contributed to the camera's demise. The dealer quoted my a price of $1,100.00 to replace the camera. I declined and went home to try another avenue of repair. I took the camera out but could find nothing I could repair myself. I called the dealer and was quoted a price of $723.00 for the camera by itself. I still declined and decided I can do without the backup camera for awhile until I can find a used one or a cheaper replacement.
