Bluetooth transmitters are super useful accessories for any car or vehicle. This review looks at the best car Bluetooth transmitters on the market and outlines important things to think about when choosing one.
Advantages of a Bluetooth transmitter
Not every car features an input from a phone. Some more modern cars include a Bluetooth or aux connection that let you plug your phone directly into the car speakers, however not many do, and not all of us can afford a new car.
There are a couple of advantages to using a Bluetooth transmitter.
- They are wireless, which keeps your car clutter-free.
- They can easily connect with your phone or other device and play your favorite tunes.
- They are easy to use and don't require any installation.
- They can be used in any car with an aux port, so you don't have to worry about compatibility issues.
- They allow you to talk on the phone without using your hands.

Types of car Bluetooth transmitters and audio connections
Whilst they are mostly relatively similar, there are a few variations of these types of devices.
- FM transmitter – These are the most common types of car Bluetooth transmitters. They work by converting the audio signal from your phone to a radio signal and then transmitting it to the car's radio, then speakers.
- AUX cables – some cars have 3.5mm aux inputs, where a cable can be connected between the phone and your stereo.
- Bluetooth transmitter for car aux – This works by transmitting audio data wirelessly through a Bluetooth connection. Only new cars tend to have Bluetooth receivers.
- FM Transmitter with USB port – This type of Bluetooth transmitter has an additional USB port that can be used to charge your phone while you're driving or listening to music.
