To use the latest audio technology in your car, you need a receiver that can accept a signal from it. However, not everyone can afford to buy an expensive in-dash receiver — especially if they spent most of their entertainment budget on that new MP3 player or music subscription.
An in-vehicle FM stereo modulator lets you play audio from a variety of devices using the factory radio. Simply connect your portable media player or tuner to an input on the modulator and select an FM radio channel that’s not being used by a local station. The modulator sends an audio signal to that station so you can listen through the stereo system.
Access your favorite music even on an ancient receiver by getting a car FM transmitter from OnlineCarStereo.com. We carry both hard-wired and wireless FM modulators for your needs. A hard-wired modulator connects directly to the vehicle’s antenna cable on older systems or via a USB port on newer receivers. They then broadcast audio using RCA or 3.5mm stereo inputs. Modern Bluetooth FM transmitters are powered by the cigarette lighter socket, and after pairing with your device, they send a low-range radio signal to the FM tuner. Some modulators have a ground loop isolator, metal housing and other features to block out unwanted frequencies for a clearer audio signal.
Whatever type of FM modulator you choose, you’ll get to hear what you want without expensive, time-consuming receiver and stereo upgrades. These transmitters work with portable music players, smartphones, DVD players, satellite radio tuners, gaming consoles and many other devices. Using a modulator wirelessly with your smartphone can also enable hands-free calling for safer driving. Use our Vehicle Fit Guide to find a transmitter that matches your factory setup or call us during business hours for expert support. We offer a 60-day guarantee so you can buy with confidence.
