Has the glass fallen out or cracked on your Toyota Prius's side mirror? This is a complete replacement unit from AutoVision. It includes not just the heated mirror glass itself, but also the essential plastic base plate it attaches to. This is for the LEFT-HAND SIDE (which is the passenger side in the UK and other right-hand-drive markets; check for your location!). It fits Prius models from 2003 to 2008. The glass is heated, which is great for defrosting on cold mornings, and it has a silver/clear finish. It attaches with clips for a secure fit. Part number is GP861. A much easier and often cheaper fix than replacing the entire mirror assembly. Get a clear view and restored defrost function with this direct replacement part.
