The way it works is its circuitry isolates any ground loops in your stereo (depending upon how it was installed, you may have a bad ground and that can cause an annoying whine).HIGHLY recommended for anyone who wants to listen to their music and charge at the same time.

very crappy quality 3.5mm connections, if the cables move even slightly the sound cuts out - don't buy this, better to buy a ground loop isolator with RCA connections.

I figured I needed a ground loop isolator on the power connection of the radio itself to elimate the noise but saw this and decided to give it a chance

I found that a Radio Shack unit, with much larger transformers, did a far better job of eliminating hum from a ground loop in my stereo.
