An FM transmitter is a small device that allows you to transmit audio from your phone to your car radio using radio frequencies. It’s an ideal solution for drivers who want to listen to music, make hands-free calls, or charge their mobile devices in cars without a modern multimedia system. Thanks to Bluetooth technology and USB input, a car FM transmitter is an affordable way to modernize older vehicle models.
How Does an FM Transmitter Work?
A car FM transmitter works by broadcasting an audio signal from a device (such as a smartphone) to an unused radio frequency (e.g., 87.5 MHz). All you need to do is set your car radio to the same frequency as the transmitter. The device connects to your phone via Bluetooth, allowing you to play music, make phone calls, or use GPS navigation apps.
Some models also support wired connections via USB port, cigarette lighter socket, or memory card reader, enhancing their functionality. This means you can enjoy your favorite tracks even if your car radio doesn’t have built-in Bluetooth.
FM Transmitter Design and Features
A Bluetooth car FM transmitter is most commonly installed in the vehicle’s cigarette lighter socket. It usually features a USB port for charging your phone, control buttons (e.g., for adjusting volume or answering calls), and a display showing the current FM frequency.
Typical built-in functions include:
-
hands-free call support,
-
mobile device charging,
-
music playback from a USB flash drive (USB FM transmitter),
-
additional features like voice assistant, equalizer, or automatic volume adjustment.
These features make modern car transmitters practical and multifunctional accessories for any vehicle.
FM Transmitter – Which Model Should You Choose?
The choice of a Bluetooth FM transmitter depends on your needs. If you’re simply looking to play music from your phone, a basic Baseus or Remax FM transmitter will do the job — offering good sound quality and easy operation. For more advanced features, consider models from Hoco or Blue Star, which often include device charging capabilities, better microphones, and additional Bluetooth transmitter functions that enhance overall convenience.
Make sure the transmitter has a USB charging port and offers fast, stable pairing with your phone. It’s important that it delivers a steady signal without interfering with the reception of other radio stations.
How to Connect an FM Transmitter to Your Phone?
Connecting an FM transmitter is very simple:
-
Plug the transmitter into your car’s cigarette lighter socket.
-
Set the FM frequency, e.g. 87.6 MHz.
-
Tune your car radio to the same frequency.
-
Pair your phone via Bluetooth (usually displayed as “BT-Car”).
-
Done – you can now listen to music, take calls, and charge your phone.
Tip: Choose a frequency that isn’t used by local radio stations to avoid interference.
