Took about 20 minutes to install. Works great. I was worried that a lot of the ads do not include up to the 2012 model year but everything works. The instructions could be a little more thorough. For example, there are 3 extra wires and 2 of them are labelled for a different model year. However, the 3rd wire was labelled, "see instructions" but there was nothing in the instructions about it. An email to Sonic confirmed it was not needed for my car.
