How to replace a 2007 Mazda3 Compass Auto Dimming Mirror with rain sensing wipers
 

I have a 2007 Mazda 3 Speed. I have a regular rear view mirror with rain sensor. I want to replace it with an auto Dimming, compass rain sensor rear view mirror. Is there one available for a 2007. If so is it easy enough to replace myself. Any instructions would be helpful. Thank you.
