FM Transmitter Buyer’s Guide

Driving is a lot more enjoyable when you can listen to your favourite songs. Older cars can be restrictive in their audio capabilities, it can mean you are limited to listening to the same few radio stations and that’s it.

A Bluetooth FM transmitter is a low-cost way to play your music and podcasts without needing to invest in a whole new music system for your car.

All a car needs for FM transmitters to work is a cigarette lighter and a radio, that’s it. You plug the transmitter into the cigarette lighter, connect your device, match the transmitter and car radio’s FM station and it’s as simple as that.


The functionality varies between FM transmitters. Some simply allow you to connect your phone via Bluetooth or an aux cable and listen to music while others offer a range of features that include an LCD screen, compatibility with different sources, adjustable controls and taking hands-free phone calls.

When choosing an FM transmitter, consider which of the following features are important to you so you can find the best option to suit your needs.


Key Features

  • Automatic scanning – the transmitter should be able to automatically scan through the channels to find a suitable frequency for you to use, rather than you having to search through manually. Auto scanning is a big help and saves time when you are on the go.
  • Preset stations – this allows you to save stations so you don’t need to search for new stations every time you use the transmitter.
  • Audio sources – some FM transmitters give you the option of playing music from a range of sources including Bluetooth, aux cable and USB drive. As well as this, the transmitter should be compatible with a range of file formats including MP3, WMA and WAV.
  • Power button – to avoid the FM transmitters using power when they are not in use, they should have an on/off button. This way you can easily see when the battery is draining.
  • USB ports – you will see that some FM transmitters have one or two USB ports that allow you to charge your devices while you drive and listen to music. This is very convenient and is a great feature for many users.
  • Battery monitor – if the transmitter has a screen it may display your cars battery voltage so you can keep an eye on the battery health. This is important for safety and can be incredibly helpful.
  • Ease of use – most car FM transmitters are simply plug and play. For safety and convenience, the device should be easy to operate with a clear screen and simple buttons. Check the size of the screen and buttons before you buy to ensure easy one-handed operation.
  • Built-in microphone – some FM transmitters include a built-in microphone to ensure hands-free phone calls are clear and high quality. This feature means you can answer calls and have conversations safely while concentrating on driving.
