If you are uncertain of the features to search for, selecting the best Bluetooth transmitter for your car can be difficult. But, by adding one to your vehicle, you can make long journeys far more enjoyable by streaming various sources of entertainment.

Unlike modern vehicles, older cars tend to have simple FM and AM radios, especially if they were built before Bluetooth even existed.

Fortunately, Bluetooth transmitters offer you more flexibility in vehicles of any age as transmitters use short-range frequencies to send and receive information to Bluetooth-compatible devices. This means you can play music and podcasts, for example, from your smartphone with ease to keep you entertained during your car journeys.

With that in mind, if you're looking for something premium, like this Sumind BT70, or you're after something a little cheaper, like this IMDEN FM Bluetooth Transmitter, then we've got you covered.

Stick around too because we've answered some of the most commonly asked questions surrounding Bluetooth transmitters to help you figure out which device is right for you and your vehicle. That being said, let's get into it...

Frequently asked questions (FAQs)

Finding the right Bluetooth transmitter usually throws up a ton of questions. Don't worry though because we've answered some of the most common queries right here.

What is a Bluetooth transmitter?

A Bluetooth transmitter for cars is a device that allows you to stream audio from your smartphone or other Bluetooth-enabled devices to your car's audio system. Using audio signals transferred via Bluetooth to the transmitter, the devices can use your car's audio system to relay the sound.

Bluetooth transmitters are often used to upgrade older car audio systems that don't have Bluetooth connectivity, allowing you to easily and wirelessly stream music, podcasts, and other audio content from your phone while you drive. They are typically compact and easy to install, and can be powered using your car's cigarette lighter or USB port.

In addition to streaming audio, some Bluetooth transmitters for cars may also include hands-free calling functionality, allowing you to take phone calls while you drive without having to fumble with your phone or take your hands off the wheel.

How much should you spend on a Bluetooth transmitter?

How much you spend on a Bluetooth transmitter will depend on your budget. However, they do tend to be quite affordable, so you don't necessarily have to break the bank to get a great device.

Spending a little more will often mean you get the best, uninterrupted audio quality possible as well as additional technology like charging ports and noise cancellation, generally speaking.

That being said, the price difference between a premium bit of kit and a relatively inexpensive device tends not to be that much, so we'd recommend exploring a variety of price options to pick out a transmitter that's right for you.

Can a Bluetooth transmitter connect to multiple devices?

The answer to this question will vary depending on the transmitter, although the short answer is yes, there are some devices that can simultaneously connect multiple devices at once.

There are also some transmitters, like the Anker Roav T2, that can remember previously paired devices to make reconnecting that bit easier each time you step into your vehicle.

Can you leave a Bluetooth transmitter plugged into your car?

Bluetooth transmitters should be safe to leave plugged into your car.

While driving, the transmitter will use a small amount of power from the battery; however, this energy will be recuperated by the alternator as you drive so you don't need to worry about it draining your car.

When you switch your car off, your transmitter should no longer be able to draw power from the battery and will, therefore, eventually switch off itself.

What is the range of a Bluetooth transmitter in a car?

According to Sony, the typical range of a Bluetooth transmitter is around 30 feet (10 metres). However, it's important to note that this range is not a strict limit and can be influenced by factors such as the strength of the transmitter, interference from other devices, and physical obstacles like walls or metal objects.

It's worth mentioning that the range may be slightly different for different devices, and newer Bluetooth versions, such as Bluetooth 5.0 or higher, may offer improved range and stability compared to older versions. Additionally, some Bluetooth transmitters may employ advanced technologies like signal amplification or external antennas to extend the range.

If you want to maximise the range of your Bluetooth transmitter in a car, it's generally recommended to keep the connected devices within close proximity and ensure a clear line of sight between the transmitter and receiver. This can help minimise potential interference and signal degradation, resulting in a more reliable connection.
