Today I installed the Homelink/auto-dimming and compass mirror and it took only 5 minutes. I removed the trim, twisted the mirror clock-wise and with a tiny screwdriver, released the wiring harness from the old mirror and then reversed the process and it works beautifully! I don't have the automatic high beam option, so I used mirror P/N 51169192335. I purchased a used one on Ebay for $100. This has to be the best upgrade I could have done to add convenience to the car. Thanks for posting this Xpander and others that provided the details!
