I have a hummer and System Addicts did a pretty good job on it. System Addicts installed a back-up camera and a pretty good sound system that is working very well. It has speakers, a built-in DVD player, and a port for my iPod. It is pretty good because I can easily back my truck without any interference with my back-up camera. System Addicts is near my neighborhood and they have worked on other vehicles before. They did tinted windows for me since I had a newborn baby. From there, I just required more of System Addicts' services!
