If you haven't seen it yet, the new rear view mirror in the latest BMW G series models really is a dramatic improvement. It is wider, has an almost borderless design and is much thinner. To top it off, the homelink buttons are redesigned along with the LED dome (now gone) you see on the older mirrors!
Its a HUGE improvement both visually and functionally, and I knew I had to make the change! The mirrors new are rather pricey, but if you look around especially on Ebay or from wrecked models, you can find one much cheaper like I did.
The change is non destructive, so you could always change back if you leased your car, or wanted it back off, and really isn't hard to do.
All of the details are in the video, and this an easy change for HUGE benefit, especially in a car like the M2C with a really small mirror.
