 Question: What is the difference between an FM transmitter and a Bluetooth FM transmitter?

 An FM transmitter transmits the music/sound signal via FM frequency.

 It does not require Bluetooth. It makes a physical connection of the phone and the transmitter. ( much like connecting the 3.5mm headphone jack). It is easier to use without the frustration of pairing the two devices upon each to use.

 A Bluetooth FM Transmitter works much like an FM Transmitter. However, it uses Bluetooth technology to pair the phone and the transmitter. There is no physical connection between the two devices. This requires pairing of the two devices on each use. This could be frustrating for some and Bluetooth will drain the phone battery.

FM Transmitter Troubleshooting Tips

  1. HEADPHONE JACK: The use of a cover on your device may prevent the headphone jack from inserting fully into your device's headphone port. If you do use a cover, try removing it and then re-insert the headphone jack.
  2. AUDIO SIGNAL: If you are experiencing issues with the audio signal, test the FM Transmitter with another device, if possible (another phone, iPod, etc.). If the FM Transmitter works as expected with another device, then the issue is most likely isolated to your device.
  3. VOLUME: For best results, set the volume on your device to maximum, and adjust the volume on your vehicle's stereo as needed. To protect a user's hearing, most devices contain a feature that limits the volume coming from the headphone port, so you may need to check your device's settings for this volume-limiting option and then disable it.
  4. STATIC: To eliminate or minimize static, use frequencies at the lower end of your vehicle's stereo's range, and also place the device on your vehicle's dashboard or passenger seat, away from the FM Transmitter itself. When properly calibrated with your vehicle's stereo, you should not be bothered by static.
  5. FM FREQUENCIES: There are three " fixed " station for you to choose from. 87.9 works for 95% of people in the United States. For quick adjustments in the future, you can use the preset buttons on both the FM Transmitter and your vehicle's stereo to save these unused frequencies.
  6. POWER: If the FM Transmitter does not turn on, then test it in another vehicle, if possible. If it works as expected in the other vehicle, then the issue is most likely with your vehicle's power port. If it fails to work as expected in the other vehicle, then check to see if the fuse in the FM Transmitter has blown. The FM Transmitter is equipped with a 3-amp/250-volt fuse which is accessed by unscrewing the two-piece metal tip. 

Set Up Trouble Shooting Tips 


Sound transmission through the FM radio waves is a tricky business. ( This is one of the reasons why the major manufacturers DO NOT feature it on the smartphone.) There are many factors that could result in your sound transmission to be less than ideal. Your vehicle and location are all important variables. I've personally tested on hundreds of different vehicles to make sure that this gadget is compatible with most vehicles and the sound is at it's best quality.

Make sure the volume of your iPhone is set at about 60% to 80%. Max volume or low volume of your phone will cause distortion and interference to your sound. You can set the volume thru your car radio. 

Make sure the transmitter is plugged into the phone firmly without a protective case. Some phone case will cause a gap in connection which result in less than desirable sound quality. Take the case off and try the transmitter again.

Try it with another iPhone / Car or location.... this will allow you to isolate culprit of the static or other noises, and provide the best sound quality for your enjoyment.

As mandated by the FCC or your local equivalent. In the USA, the rule requires an ERP of 0.01 µW, or 10 nW, or -30dBm. So ok, you're only going a meter or so, so that signal at the car's antenna should be around -40dBm to -45dBm, depending on the actual distance. And a typical consumer FM receiver should be good to -90dB or so receive sensitivity. When it comes reception and sound quality. It's all about the antenna! Where's your antenna? Where's the FM transmitter? Chances are, the answer to the latter is "somewhere near a DC outlet". So if you have one of those in-windshield FM dipole antennas, you might have a pretty good signal, though the direct path to your antenna might be through your dashboard. But if your antenna is one of those shark fins on the roof, you have a 5-10 millimeters of steel between your transmitter and your receiver. The final sound quality will be degraded accordingly. The FM radio band is essentially a “line of sight” band. To hear a signal, you have to be able to see the tower. FM radio does have some power to penetrate buildings and the like, but ultimately the maximum distance that can be achieved is mostly set by the curvature of the earth. But on the “medium wave” band, radio waves can be ducted and can curve around the earth, especially at night.

FM radio sounds so much better is that the extra space effectively allows them to send more data. Without getting technical, they have 20x as much space, and so can send not just a wider range of audio frequencies, but also stereo sound, and other more modern improvements like the Radio Data System - Wikipedia.
