Gentex Auto-Dimming Mirror with Homelink Install

While looking for a good garage door opening solution for my MY01 996 C4, I came across some posts referring to the Gentex auto-dimming mirror with Homelink. Some posts suggested that there was a VW/Audi adapter that would allow this universal fit mirror to be installed on a 996 windshield. Other posts suggested that it was easy to tap into the existing dome light and sunroof switch wiring. So I decided to give it a go. It was a relatively easy install, and one of my best mods yet.

I finished my install and thought I'd post my experience. I bought a mirror off ebay, everything works on it, good seller. When twisting my old mirror off, the mount came off the windshield, so I decided not to use the VW/Audi/Porsche mirror adapter. Instead I started over by gluing on the more standard wedge mount. I have a cab and then discovered there is not switched power on cabs in the dome light area. So, I routed the wires down to the phone connector in the center console. At this point I discovered that phone connector is very rare and unusual. I emailed Tyco and their response was that it's a propriety BMW connector and they couldn't sell it to me. Becker was the only place I could find that had the mating connector. The only problem with the install is that the mirror vibrates some. This is especially true at high speeds with the top down. I'm hoping the find a way to dampen it. The set screw on the mount is tight, the play is from the ball and socket joints in the mirror.
