Good quality product. But to do what I have to do, that's enough widely (Set of music I enter my Car). To those who think the sound saturates. Think down the volume of your player (Phone, iPod, MP3 player ....) and turn up the sound on the radio station. For if the signal from the player is too high, it may saturate. A digital audio signal, and more accurate and powerful than a magnetic strip, which is better quality - (in my opinion). When sending sound through the adapter, its not clear the magnetic puck on the tape, and then is returned to the speakers.
Otherwise, another tip if your adapter jumps all the time. You can remove, gently toothed washers, helping to drive the magnetic stripe (that there does not exist).
If the sound does not come out, press the front of your change of position of arrows. Face A Face B. Normally this works.
Otherwise, if none of this works. Change position .... lol ...
Good night.
Good trip and good listening.
