What is an FM transmitter?
An FM transmitter lets you listen to your favorite music through your car radio. It plugs into the cigarette lighter and automatically broadcasts the music present in a smartphone on a chosen FM radio frequency. Then simply select the FM band with the car radio as if you were listening to your favorite channel.
An FM transmitter is a convenient and inexpensive option to send music to your car stereo from an external device, but it’s not always easy to get it started. The device needs optimized settings to work properly depending on the model.
How does Bluetooth FM Transmitter work?
An FM transmitter works by converting a musical signal into radio waves. It transforms the sound source into an FM radio wave and then broadcasts it so that it can be picked up by car radio. The smartphone connects to the transmitter via a jack or via Bluetooth.
It’s a wireless solution that works with virtually any car, but it can suffer from interference and poor sound quality. Fortunately, newer models tend to be much more reliable and some can charge your device and act as a handsfree for smartphones.
How to choose a good FM transmitter?
If you’re not sure which FM transmitter to choose, here are some important things to consider.
You must consider the possible transmission range before purchasing an FM transmitter. The range must be good enough to allow you to use your devices anywhere inside the vehicle (for example at the rear if a passenger wants to change music).
Most models can transmit sound waves between 3 and 10 meters. This is more than enough to get good signal quality inside your car and even outside your car if you wish.
Number of frequencies
For your FM transmitter to work properly, you must have a free FM frequency, that is, not used by local or national radio. If you live in a city or a densely populated area with many FM radio stations, it will be difficult to find a frequency.
For this reason, before purchasing an FM transmitter, you must verify that the device offers a broad spectrum of frequencies from 88 to 108 megahertz. This means that you will have the best possible chance of getting a clear signal without interference.
The best sound quality without interference is possible using Bluetooth technology. I advise you to limit your search to models compatible with this technology. It should be noted that more and more devices are filtering noise to minimize noise disturbances.
The ideal location for your FM transmitter is between the two front seats if your vehicle antenna is located at the front of the roof of your vehicle. If the antenna is located at the rear of the roof, place the FM transmitter on the rear seat.
There may be a free frequency in your area that is perfect for your FM transmitter. But when traveling, it may be busy with a local radio station, which forces you to look for another frequency. It is thus extremely useful to have the possibility to record frequencies.
Likewise, some FM transmitters with auto seek to detect when a radio is superimposed on your signal to search for a new transmit frequency. This means that you will not have to do the research yourself, and the device will change frequency without any action on your part (except synchronization with your car radio).
There are all kinds of features in multi-function FM transmitters like a random play or fast forward.
Many models of FM transmitter with microphone are versatile since they allow the handsfree function. Compatible with iPhones and Android smartphones, you can use the buttons on the transmitter to answer a call. You will hear the sound of your phone in the headphones of the car and speak to your caller safely.
Price and guarantee
It is now possible to find a good Bluetooth FM transmitter for 10 to 20 € only. So it’s worth it to choose a more complete model for a few euros more. Remember to check the warranty period (usually 1 or 2 years) when comparing 2 different models.
How to use your FM transmitter?
To use FM transmitters the first time, I recommend that you read the user manual carefully because each model connects differently. Here are the main steps in the majority of cases:
- Connect the FM transmitter to the cigarette lighter of your car;
- Synchronize your smartphone (or MP3 player) with the FM transmitter via cable or wireless;
- Select a frequency on the FM transmitter that is not occupied by a local radio station;
- Then choose the same frequency on your car radio;
- Increase the volume according to the power of your device;
- All you have to do is start the music on your smartphone!
