I was really excited to get this for my vehicle! Watched a YouTube video on the installation and went to work. It all went great BUT...that harness is HUGE. So, I ended up having to cut a little connecting piece of plastic under my dash so I could store the harness and the BCM box under the steering wheel. I made sure I had enough room to adjust the wheel and had plenty. Once I got my din switches set how I wanted them, I mounted the control button, started the car and tried it out and OMG, do I LOVE it!! It's really easy to control, and also nice that you can tell that it's activated by the icons on your instrument cluster going on and off. All in all, I give the product a 10/10! Installation was slightly tedious but not really bad. Great job!!
