I came out of Walmart to discover my passenger side mirror on my MkVI Jetta smashed. I purchased a new one for $70 at ECS Tuning which is expensive but less than the dealer. It has a plastic mount stuck to the back and basically snaps of and back in. Run it all the way in so you can get your fingers in the outside edge and just pop it off. Unplug the heater wires, plug the new one in, line it up ans shove and it will click into place.
