Unacceptably Difficult to Install
Be warned that if you have a 2004-2007 style Toyota Prius, this is a nightmare to install. There are multiple steps that simply are impossible to perform without improvising. Unless you are extremely handy or can have this professionally installed, I would avoid this for a Prius. I did finally get mine successfully installed, but it took 3 days and lots of problem solving when the steps in the instructions were either unclear or physically impossible. What a nightmare. And yes, I had the proper fit kit for my car.
