*PLEASE READ IN FULL* I have been struggling for a month now to get my back-up camera and steering wheel controls to work. The seller has been EXTREMELY responsive concerning my issues and has been going out of their way to get these to work. I have never had a seller work so hard to resolve an issue. They still do not work, but with every response I get from them I am getting closer to resolving these problems. I am confident that together, we will get this resolved soon. Amazing responses!
