Not all cars come with built-in Bluetooth or Apple CarPlay — especially older but still reliable models. If you want to stream music, take hands-free calls, or charge your phone while driving, a Bluetooth FM transmitter is one of the easiest upgrades you can install in seconds.
A good FM transmitter allows you to:
- Play music wirelessly from your phone
- Make safer, hands-free phone calls
- Charge one or multiple devices
- Upgrade your car without replacing the stereo
