Just wanted to give these guys a glaring review. I bought a bluefusion for my yukon and was having trouble with the sound. I contacted them, they sent me a new unit, still didn't work. So i contacted them again they said well lets try a new harness and sent me one out yesterday. They have gone above and beyond to help me out without so much as a question. I think i recall there being a rep on the boards but i can't remember. I would definitely do business with them in the future and would recommend them to anyone.
