I had a Caddillac STS for a few years which have the eletro dimmin rear view mirrorand side mirrors. I loved it. Not only do I feel that the electro diming actually works better than he leverl activated dimmers but having the side mirrors dim too was great. With so many SUV's on the road and a low car you get a lot of headlight reflections in these mirrors. I wish I had the auto dimmer and I didn't know it was included on the 04's. Has anyone successfully transplanted one into an 05?
