Best bluetooth FM transmitters (2022)


With modern technological advances came Bluetooth connectivity which eliminated almost all needs for wire and cable connections. Today, virtually any vehicle comes with a stereo that works with radio frequency or Bluetooth.

You can have nearly every device connected to your car stereo system via Bluetooth or even browse for music online with newer sound systems.

However, if you have an older car model, you might not get more than the usual music played by local radio stations. You are probably unable to connect any device; be it a USB port, AUX port, or Bluetooth connection. And therefore, you can’t play the music you like!

Lucky for you, no matter what car you have, as long as it has a working stereo system, you can turn to Bluetooth FM transmitters. In this article, we will discuss what FM transmitters are, how they work, and review some of our top choices.

What Is A FM Transmitter?

A Bluetooth FM transmitter works like a regular radio frequency transmitter, such as your car radio, similar to the high-powered transmitters radio stations use for audio transmission.

It works by sending a signal on a particular frequency band that you can dial into your car radio. It can also connect to your smart device and transmit data without a USB or AUX cable.

An FM transmitter allows a connected device to stream music stored in it on an FM frequency. The best FM transmitters will provide clear sound quality without static interference and a stable Bluetooth connection.

For example, the audio source would be your smartphone via Bluetooth to the FM transmitter, which acts as an FM station and broadcasts a signal to which you can tune your car radio.

It does not impact your FM signal clarity, but it uses a band to transmit music or sound to your car. Moreover, you will hardly face interferences since it is a few feet away from your car’s radio antenna, but the further away it is, the better it might stream.

Generally, an FM transmitter is a simple device with a USB port or Bluetooth connectivity and plugs into your car socket. But other FM transmitters can come with more few extra features such as a built-in microphone, hands-free calling, dual USB charging ports, micro SD card, etc.

Where And How To Use A FM Transmitter

Now that we have an idea of what a FM transmitter is, let’s talk about how to use it. You need to know a few things and keep them in mind for your safety and to prevent any problems.

Firstly, you should never try to perform connections or operate the transmitter while driving the car.

Secondly, ensure that you have installed the transmitter where it is not in the way of airbag functionality. It should not interfere with the driving and be out of children’s reach.

Lastly, you can only use the FM transmitter while your car is running. If you leave it plugged into your car’s interior cigarette lighter socket while the vehicle is not running, it will drain your car battery.

You will first have to program your car stereo to tune into the FM frequencies your transmitter is working with. Begin by powering the car stereo, turning the volume down, and setting it to FM.

Then, depending on the FM band your transmitter will transmit on, you select an available frequency so you can begin streaming audio to your car. However, the reception may change as you travel between locations.

Therefore, if the selected frequency is occupied, choose a different one that is not.

Next, to install your FM transmitter, you must first select the same frequency you set on your car stereo. Then, connect the stereo mini plug to the headphone jacks on your device or connect them via Bluetooth.

Finally, you can insert the transmitter in the cigarette lighter socket until the frequency channel is visible in the display window.
