This is One of at least 11 versions of rearview mirrors found in W203 and W209 chassis cars. You can NOT go by the pictures, several of them are identical in every external physical aspect even down to the connectors and number of wires... THE DIFFERENCE BETWEEN THEM IS INTERNAL, circuitry, microphones, data transfer, etc....and all depends on your car's options. IF you do not have a part number ID tag on your old one to reference then you NEED to have a Dealer run the VIN# of your car and tell you the proper rear view mirror to mate with it. If you don't do this, obviously something (s) will no longer work, like voice commands, blue tooth, etc.. 203 810 32 17 // From salvaged 2004 C-class w/ Alpaka Grey trim code 7E94. Fit a Limited number of W203 and W209 from 2002 through 2009. Besides internal sensors, it has two plugs. Flat one has 6 wires and rectangular one has 3 (out of 6 spaces).
