FM Modulators stream the audio from your personal MP3 player to your car's FM stereo. While modulators are convenient and quick to install, they won't always deliver the best quality audio. If you're having trouble with your modulator, there are a couple of steps you can use to get the most out of your device.
Instructions
1. Turn on your car, and turn on the radio. Make sure the radio is set to receive FM channels.
2. Tune the stereo to a station that is has no signal. If all the stations receive some form of signal reception, choose a station that has the lowest quality reception.
3. Plug the modulator into your MP3 player, and turn the modulator on. If it draws power from your vehicle, plug it into the power outlet on the dashboard.
4. Tune the FM modulator to the station set on your car's stereo. Press "Play" on the MP3 player or other device, and set the volume on the player to about half the maximum. Set the volume on your car to the desired listening level.
