Catfish - in relation to retrofitting a rear view camera onto your vehicle, BMW dealers have a retrofit kit they can order for retrofitting to vehicles that have a business nav or professional nav CIC. The retrofit package includes the rear view camera module that provides for object detection and parking tracers along with the camera. If you ordered your BMW without it, you'll likely not have the wiring in place and the module for just a mere attachment of the camera.
I was told this at my bmw dealer when i took delivery of my f10. unfortunately they wanted to charge me 2,100 for retrofit and i decided I could live without the rear view camera so long as the PDC was working. Annoys me to no end that a rear view camera doesnt come standard in vehicles of this price range.
