Query: Horrible Product. Does not work!

Jut horrible! Brand new out of the box it does not work (does not charge my iPod). When I plug it into the cigarette lighter by itself, the green light comes on indicating that it is charging (but there is nothing plugged into it!!), and if I have my radio on, I will start to hear a slight buzzing sound. As soon as I plug in my iPod via the provided firewire cable, the green light goes out and it just sits there getting hot and not doing anything. It's not the fire wire cable, since I used it with iPod's standard charger. The problem is with the actual unit that plugs into the cigarette lighter.
