Query: Does not work

I read bad reviews for this product but decided to try it out anyway.I got this in mail few days ago. I was pretty excited and tried it out immediately by connecting my iPhone to the car stereo. It was disappointing to see that the thing really does not work. The sound volume is unusably low and cranking up the car system sound brings up more noise than the mp3 sound. Got to return it. I would suggest readers to not waste time with this product.
