I installed M5 mirror on my 535D (09/2005). Everything work except auto-dimming. The back side of the M5 mirror glass 4 wires: 1 connector with a violet and black wires; one brown and black. On the oem back side of the glass mirror: one connector with 4 wires; black, brown, red and violet. Is someone can say what about the 4 wires on the m5 mirror glass, black, violet, brown and black which one correspond on the oem; black, brown, red and violet. Need an help, or does exist M5 glass mirror for model after 09/2005 with a multiplexage box on the mirror like the oem have on my car. Sorry for my English.
