I have a 2004, and I love the mirror. They work very well compared to other cars I have owned with the auto dim. This is definitely something I would pursue if I had a Crossfire without it. I just picked up one from a Chrysler Concord to put in my Liberty, and will see how well it works. The main reason there is more than just a power wire is so when you go in reverse the mirror will "un dim" so you can see out the back better. Most have a power/on button, the Crossfire mirror has none and is always active (unless in reverse).
