Query: Unclear; not worth the money

I bought this product before a long road trip. I connected it to my iPod to play MP3's along the way. The sound quality is horrible! The static was either hissing in the background or overpowering. I never found a frequency that did not have static. Also, the music sounded like it was being played in a cavern through the wall. It was muted and echoing. I returned it as soon as I got back from my trip. Not worth the money.
