What is aux transmitter?

An aux transmitter, also known as an auxiliary transmitter, is a device that enables you to play audio from your phone, tablet, or other devices through your car stereo system. It is a small, portable device that connects to your device's headphone jack and broadcasts the audio signal wirelessly to your car's FM radio frequency. This allows you to listen to music, podcasts, audiobooks, or phone calls through your car's speakers without the need for any wired connections. Aux transmitters can be easily plugged into your car's cigarette lighter socket or USB port for power. They are also compatible with most devices and car models, making it a convenient upgrade to your car's sound system.
