Query: Very poor sound quality

Purchased and tried it with three different ipods in three different 2000 to 2007 vehicles. In all cases the sound quality was unacceptable. Sound was equivalent to a FM station with very poor reception. Even with no music playing it was very noisy. Adjusting the position relative to the vehicle antennae helped only slightly. After deciding that the unit was defective, I contacted Belkins who were very helpful and returned it for another. The new unit worked identically to the first. I'm absolutely amazed Belkin, as a leader in ipod accessories, would put a product like this on the market. However, the bottom line is that it does not work. It is ridiculously poor.
