Best Bluetooth FM Transmitters Buying Guide

What to Consider When Buying a Bluetooth FM Transmitter

From reading through our product selection, you will have noticed that there are several common features which unite these devices and some which are unique. So, here are just some of the main points which you may want to consider when choosing the right one for you.

  • Audio Experience

The overall audio experience that the device offers is worth looking at in more detail. While the sound quality depends on your car speakers, you could look into more detail at how much interference previous users have experienced. This is where reading some of the reviews readily available online can prove to be highly useful. Sometimes, it can end up being a matter of making minor adjustments to the frequency until you find the setting which is best for you.

  • Compatibility

The issue of compatibility comes in two parts: your car and your smartphone. Since you are considering investing in one of these devices, you are likely to have an older car which doesn’t already have Bluetooth compatibility, but you should double check the guidelines to ensure that your vehicle is supported. Generally, as long as the car has a cigarette lighter and a radio, it should support one of these devices. As well as checking your car’s compatibility, you should also check that your smartphone, tablet, MP3 player or whatever else you want to hook up is connectable as well.

  • Ease of Use

Since this is a device which you will use while driving, you will want it to be as easy to use as possible so that it doesn’t distract you. Some of these FM transmitters come with additional buttons, added remotes etc, so you need to be comfortable using all of these. Different modes of connectivity are also an option, so you need to work out exactly how you plan on hooking up your device as well. It is worth having this information before deciding to make an investment.

Installing a wireless FM transmitter should be a straightforward task. You simply need to plug the device into the power source (the cigarette lighter), turn on your phone’s Bluetooth to find the connection, choose the audio frequency, and select the music that you would like to play.

It is also worth checking out the screen and buttons in more detail. Some will offer more buttons to adjust the mode, volume, skip song etc whereas others will have fewer buttons which only provide the option to answer calls. Some will come with an off switch, while others will require you to unplug it to power down. Again, this is something which is worth knowing so that you don’t end up draining your car battery without realizing. You should also check out what information you can get displayed directly through the screen including song name, caller ID, car battery levels etc.

  • Extra Features

Playing music and making hands-free calls are the main features of devices like these, but you should also consider the extra features which may encourage you to go for one above the rest. Some come with built-in voltmeters to allow you to check up on your car’s battery levels, while others have additional USB ports for charging facilities. Some come with location settings to allow you to track down your vehicle using an app, while others have more control when it comes to skipping songs, changing music-playing mode etc. Ultimately, your own personal preferences will come into play here.

Benefits of Using a Bluetooth FM Transmitter

Obviously, whenever you are investing in any upgrade for your car you will want to answer questions about its major benefits, and the same is certainly true of a Bluetooth FM transmitter. So, here are some of the main advantages which you can expect to enjoy by buying an FM transmitter for your car.

  • Easily Play Audio in Your Car

While many modern cars are now being fitted with Bluetooth capabilities, older vehicles (and more basic models) don’t have the same advantages. A Bluetooth FM transmitter is a simple and wireless solution to the problem which only requires you to plug in the device to your car’s cigarette lighter and pair it with your smartphone or other devices. Suddenly, you have access to all the music and audio files that it can provide. Ultimately, this makes your morning commute or long drive a much more enjoyable experience, and one in which you have a higher degree of control when it comes to your audio entertainment.

  • Hands-Free Calls

Nowadays, people always like to stay connected. But using your phone in your car can be dangerous, and accident rates due to distracted driving have spiraled over the past few years. The built-in microphone function of these devices means that you can answer calls and speak to people while still concentrating on your driving. Many of these devices also come with the function of automatically cutting your music and allowing you the option to take or reject a call at the touch of a button. You have connectivity in your car without needing to pull over to answer a call or risk having an accident by fiddling with your phone in the car.

  • High-Tech Features

Our growing reliance on smartphones has meant that keeping them charged has become a constant issue. Most of these devices come with one or two charging ports which means that you aren’t in danger of letting your smartphone go flat, which is particularly important if you are relying on it for GPS. As we have already mentioned, many come complete with a voltmeter for you to check your car’s battery – information which you won’t get from older vehicle models.

  • Simple and Affordable Car Upgrade

While many car upgrades are expensive and/or challenging to install, here is one which you can add to your vehicle in a matter of seconds that can significantly improve your driving experience. As well as being affordable, these devices are small and stylish, meaning that they will look perfectly natural inside your car. Many come with different design choices, allowing you to select the one which looks best inside your car.

FM Transmitter Hack; Eliminate Static 

There is nothing more annoying than that static sound when you are trying to enjoy your favorite music. First of all, you want to start by choosing a high-quality product. Look for one with manual tuning to remove interference from local radio stations. Also, you should check for you connection options beyond aux cables. Some offer USB connections, SD card slots, and other options which can improve quality. For example, if it doesn’t seem to work well when you connect a cable, you could instead try the Bluetooth connection instead. When you plug the FM transmitter into your car, tune it and your head unit to the same frequency.

Best Bluetooth FM Transmitters FAQ:

Q:  How do FM transmitters work?

An FM transmitter is a device which allows drivers to play portable audio sources through a radio with an FM band – most commonly a car stereo. Since there is no physical connection to the radio, there are no cords required and there is also no need to upgrade the audio system in your car. Essentially, this device works by a converter taking the audio output from a pre-existing source and converting it into analog audio. After this, FM modulation will convert the signal again, allowing drivers to tune their car radio to the specific frequency that matches with the transmitter and listen to music as if being broadcast through a regular FM radio. With Bluetooth connectivity, you can pair it with your smartphone to then play the music from your phone directly to your car’s stereo or answer any incoming calls. Most of these devices come equipped with in-line controllers and display screens, as well as allowing the installation of apps to improve overall audio quality.

Q:  Do Bluetooth FM transmitters play stereo or mono audio?

As long as the original audio source in your car is in stereo and your car is equipped with stereo speakers, your Bluetooth FM transmitter should stick exclusively to stereo audio. So, the quality of sound which you can expect to receive in your vehicle depends very much on the current quality of your car audio.

Q:  Will a Bluetooth FM transmitter work in an older car?

Bluetooth FM transmitters are designed to work with a wide range of vehicles as long as they are equipped with a cigarette lighter and a radio. If you have an older car without Bluetooth capabilities, these devices can prove to be especially useful as they give you a lot more freedom when it comes choosing audio. And if your car has a hotspot or you have a lot of 4G capacity, you can even connect to a music streaming service where the options are seemingly unlimited.

Q:  Which devices will a Bluetooth FM transmitter work with?

Bluetooth FM transmitters are designed to work with all sorts of modern devices including smartphones, tablets, laptops etc. The majority are built to be universally compatible with iPhone, Samsung, Pixel etc. However, you should always double check before investing in an FM transmitter that your specific device is supported. There is nothing worse than getting a new piece on tech, only to find that your specific device proves not to be supported.

Q:  What does RDS function do in FM transmitters?

An RDS function is automatically built into many of these FM transmitters. Essentially, this means that it will transfer useful information to the screen of your device including song title, artist’s name, caller ID etc. Many also come with an in-built voltmeter so that you can also check up on your car’s current battery levels. Since the screens are relatively small, they only have room to display a limited amount of information, but you don’t want too much as this could end up distracting you from your driving.
