Once all of this is completed you will then need a coding session, to code in Auto Dim (531) and Homelink (no VO code).
Take a look at this post....

Thanks for the follow up. I have auto wipers and lights but the rear view mirror is just a standard mirror. So, I'm assuming based on your post that if I got the autodim/homelink mirror this would just be a swap as long as there is power near by?
