Bluetooth FM Transmitters

Add Bluetooth audio and hands-free calls to an older car stereo

A Bluetooth FM transmitter plugs into your 12V outlet and streams audio from your phone to an empty FM frequency on your car radio. It is an easy way to add wireless music and hands-free calling to a stereo that lacks Bluetooth. Most include USB ports so you can charge while you stream.

When choosing one, look at call quality, how easy it is to tune a clear frequency, and the charging output of the built-in ports. We curate top-rated FM transmitters on Amazon so you can compare features that matter in daily driving. A clear display and simple controls make it safer to use while parked.

FAQ

How does a Bluetooth FM transmitter work?
It pairs with your phone over Bluetooth and broadcasts the audio on an FM frequency, which you then tune your car radio to. This routes phone audio through your existing speakers.
Why is there static or interference?
Static usually means the chosen FM frequency overlaps a nearby station. Tuning to an unused frequency in your area typically clears it up.
Can I make phone calls with it?
Yes, most models have a built-in microphone for hands-free calls. Call clarity varies by model, so check the audio quality details before buying.
