I had a loose driver's side rearview window assembly, so I had them order the part when I got my YRF0 update done last week. I go in this morning to drop off the car to have the new window put on, but instead my service writer told me I could take it home and install it myself and keep the old mirror as a replacement! It was an easy install, only took me about 30 minutes. Now I have an extra mirror assembly! Sweet!
