What is a Bluetooth transmitter For Car?

A Bluetooth FM transmitter is a device that connects your car stereo to an external device such as a smartphone, an MP3 player, an SD card or a CD player. The transmitter is wireless, which means there is no cable that connects the FM transmitter to your car radio. Instead, the device usually connects to the cigarette lighter (for power) and sends FM signals that the car radio will be able to capture for broadcast as it does for a regular radio station.

To be more specific: the FM transmitter receives the audio output from the source to which it is connected (a smartphone or a CD player) usually Bluetooth, but it can also be audio cable, USB or SD / TF card depending on the model. The transmitter then converts this information into an analog format before converting it once again through a modulator into an FM signal. The car radio then picks up the FM bandwidth of the transmitter as it does with ordinary radio stations and broadcasts the sound.

How to choose the best FM transmitter?

You will quickly notice that choosing an FM transmitter is not so simple, there are many brands on the market with different functions. The price also varies a lot from one model to another. To help you choose the right device, here is a list of criteria to consider as well as a selection of the best FM transmitters you can find on the internet at the best price.

Functions

First, you should pay attention to the functions when buying an FM transmitter. The connectivity of the equipment with different devices is of great importance. Here is an overview of the features you can find:

  • An SD card or TF card slot for playing music and audiobooks from a memory card;
  • One or two USB ports to charge its peripherals and play music stored on USB sticks in MP3 and WMA formats. Some have a USB Quick Charge port for faster charging of connected devices.
  • The Bluetooth connection for wireless streaming of music from portable devices, for example from a smartphone. Beware of the Bluetooth standard, prefer at least version 4 of Bluetooth;
  • Hands-free kit – very convenient for receiving calls while driving safely and without the risk of a fine. Devices with a microphone with echo cancellation technology should be preferred if you often use this function.
  • An audio jack 3.5 to work with most even older audio devices (mp3 player, CD player);
  • A remote control to have more choices at hand and allow other passengers to control it remotely;

The size, design and ergonomics of the transmitter

The design is a criterion not to be neglected. You’ll quickly notice that there are big differences in size and design between the many models on offer, ranging from the transmitter not bigger than the cigarette lighter plug, to the one that looks like a miniaturized control tower. A transmitter should be practical and blend into the interior of your car. Once connected to the cigarette lighter, it must not interfere with access to the other functions of the vehicle. The look is important, you probably will not want to have a ridiculous device in your car that creates discomfort.

Also pay attention to the layout of the connection ports on the FM transmitter. Connected devices must not interfere with the gearshift or dashboard controls.

The frequency spectrum

FM transmitters operate on a free FM frequency (those that are not normally used by radio stations). This is not a problem in sparsely populated areas, but if you live in the city, many FM frequencies are probably already in use. A wide spectrum of frequencies means that you will have more possibilities for your transmitter to select a free frequency. Verify that the transmitter is capable of transmitting in a frequency of at least 88.1 to 107.9 to avoid unnecessary complication.

An anti-noise filter

One of the differences you may notice when listening to your transmitter compared to a regular radio station is a more pronounced background noise. This should not be the case if you choose a model with an HVAC noise filter function. Make sure that the device filters noise (HVAC technology) effectively by looking at the technical specifications and reading customer reviews and that it can operate as close to the radio as you like.

An RDS function

RDS is a display function found on most car radios. RDS stands for Radio Data System, a feature that allows you to display information on the digital radio screen about the station being picked up, the traffic status or the song being played.

There are FM transmitters that support this feature. A basic device simply displays the information on its own screen while a well-equipped FM transmitter will also send RDS additional information to the car radio as if you were listening to a normal radio station.

Transmission distance or effective range

The transmission distance can be an important consideration if you want to continue using the transmitter at a reasonable distance when you are outside your vehicle (via Bluetooth for example). On the other hand, it should not be a big problem if you only use it inside the vehicle. A transmission covering 10 meters is generally sufficient.
