WHAT IS A FM TRANSMITTER AND HOW IT WORKS
By now all the latest car models incorporate different types of technologies, which facilitate the approach between the user and the machine. Many of these technologies have been implemented to guarantee greater driving safety, but there are also many others dedicated to the playful aspect of life at the wheel.
Surely one of the major improvements in this regard has been achieved in the technologies that facilitate the dialogue between the stereo system and the mobile phone, and allow with or without wires to play your favorite tracks stored on an external memory (for example a USB key) and at the same time recharge your smartphone. Not bad, right?
Unfortunately, as already mentioned, these technologies are integrated only in the most recent cars. If you are proudly driving a slightly older model, you will not have to feel cut off from all these multimedia conveniences. Yes, you won’t have to give up anything, even if you are still fond of your car a little dated.
This is in fact possible thanks to devices such as FM car transmitters. They take advantage of Bluetooth connectivity to allow dialogue between your mobile phone or MP3 player and the audio system of your car. It is also possible to use them also for the radio, as indicated by their name, since by using radio waves they are able to settle on a free frequency, on which they can then transmit.
The result, of course, is that you will be able to listen to your favorite tracks recorded on the phone or on music software such as Spotify directly from your radio. This also means more security, as you won’t be tempted to look at the phone while driving to personalize the music being played. As always, safety is always the first thing to consider.
Now let’s see how to get the best out of your new Bluetooth car transmitter! Much of this information is very basic, but it can really make a difference!
As already mentioned, these devices allow you to freely listen to your favorite music in the car, leaning on the songs saved on another device or played by music software such as Spotify. This is really a great convenience, which makes you much less a slave to radio and now very intrusive advertisements. If you prefer, though, you can also use them to listen to radio stations or podcasts.
The operating principle of these devices is very simple, but certainly effective. In practice, they exploit the free FM frequencies to be able to reproduce, through the car radio installed in your machine, the music being played on other devices connected to them. In short, the heart of the operation lies in Bluetooth connectivity, which allows all these devices to communicate with each other.
Unfortunately, the only problem, as well as the great limitation of these devices, is the number of free FM frequencies in the area where you are. In large cities, therefore, it might be much more complicated to find a free sequence, or in any case the connection may not always be crystal clear and stable.
Obviously, if your model has more connections, it’s better to use them all. So you can play the music saved on devices connected via Bluetooth, but also USB or maybe you can also take advantage of the slots for micro SD memories! Then read the instruction manual to discover the full potential of your new FM transmitter. In some cases you could even buy a model with a comfortable hands-free system, to answer and make phone calls while you are driving, always respecting safety and the highway code!
We have already mentioned the supply of these available, but it is always good to repeat it. Check that your model is compatible with USB connection to a portable device, such as your smartphone. If not, you will need to connect it to the cigarette lighter socket of the car. To do this, you will need a special 12 V cable.
