Bluetooth FM Transmitter FAQs

Here are the answers to some frequently asked questions about Bluetooth FM transmitters.

What is an FM Bluetooth transmitter?

An FM Bluetooth transmitter is a small device that plugs into your car stereo’s cigarette lighter socket. It can receive Bluetooth signals from your phone and then broadcast them to your car’s stereo using an FM frequency.

You tune both the transmitter and your car radio to the same blank FM frequency (87.5 usually works well).

FM Bluetooth transmitters offer a cheap and easy way to get Bluetooth in your car. They are useful if you have an older car that didn’t come with Bluetooth by default.

How well do Bluetooth FM transmitters work?

Bluetooth FM transmitters usually work well if you tune them to a clear frequency. However, they can pick up interference at times.

Another common issue is that if the transmitter has a built-in microphone for hands-free calls it can be too quiet, meaning that the person you are speaking to might find it hard to hear you.

Which FM frequency should I use?

87.5 is usually the best frequency to use in the UK, though 108 can work well too. We have an article about the best frequencies to use for FM transmitters here.

Do Bluetooth FM transmitters play stereo or mono audio?

If the original audio source is in stereo and your car has stereo speakers, the transmitter should play stereo audio.

Will a Bluetooth FM transmitter work in an older car?

Yes, provided the car has a cigarette lighter and a radio.

Which devices will a Bluetooth FM transmitter work with? (iPhone, Samsung, tablet, laptop etc.)

A Bluetooth FM transmitter will work with any other device that has Bluetooth and can play audio. This includes almost all modern smartphones, tablets and laptops.

  1. Interesting report. However, one thing should be mentioned. Many that advertise using a SD card with a facility up to 32Gb simply doesn’t hold up. I have now bought 8 of these so called clever products, and ALL have failed in one way or another. None play more than 20 songs. some have terrible phone call sound and others are just badly made. I had one delivered that had unsoldered wires sticking out the back. The manufactures really need to be more truthful about th Sd issues, and start making units that are fit for purpose, even if they are more expensive.

  2. Can these Bluetooth transmitters be used in a with 15-18 yr OEM radio with no Bluetooth capability (only AM, FM, CD & Cassette Tape). I recognize music transfer would be via unused FM channel and in my case, a USB flash drive? Is music quality good using this approach (don’t have smartphone)?

    1. Yes, you can use these transmitters even if your car radio doesn’t have Bluetooth. The sound quality should be good though sometimes there can be interference as these transmitters use FM broadcasting.
