Hello everyone, this is my first post. I have a 2007 Touring edition which I just installed a Kenwood KVT-617 in. There are two problems that I am hoping someone can help me with. The first problem is that it on will turn on when I directly touch red and yellow wires, but then will not turn off with car. The second problem is their is no DVD sound, I can see the picture but no sound. If someone could help me I would much appreciate it.
