My Sprinter Cargo Van came without a rear view mirror because the rear doors had no windows. Having gotten rear windows as part of my RV conversion, I ordered a rear view mirror from The Van Mart. The mirror came with a new plastic piece with an opening for the mirror to replace the solid plastic cover that had no opening. I followed the instructions in The Van Mart’s installation video and although it took multiple attempts, I was eventually able to install the mirror and the new cover. The result is awesome! In addition to the back up camera (with Mid City Engineering's module that allows me to use the camera while driving), I now have a rear view mirror that allows me to quickly see what’s happening behind my van at all times without having to turn on the camera and get the right view. Just awesome.
