Mercedes W124 auto dimming mirror with integrated display for use with a backup camera. Also has 2nd aux video input that can be used for DVD or something like a GPS (assuming your GPS has a video out). This mirror has a single button which is used to turn the auto dimming on or off. When the backup camera is being used, the single button adjusts the brightness of the display. I can build this mirror for the W124, W123, R107, W126 and W201.
