I bought a Monster FM Transmitter after reading the Amazon reviews which are pretty evenly divided pro vs con. I didn't expect the sound quality to be as good as playing a CD, but I did expect it to be as good as radio reception. It was a no-brainer setting it up, and it worked, but I was completely disappointed in the sound quality. I tried several stations on the radio, and it was like I was listening to a poorly tuned station. The background static on the best channel was distracting and the sound quality so poor that I immediately returned it.If you are concerned with sound quality, this is not a viable way of getting iPod music through your car stereo.
