Most FM transmitters don't have "Auto Scan" function which will help find a vacant frequency automatically to avoid using occupied channel. The channel occupied would generate Radio Frequency Interference (RFI), which can be defined as an unwanted audible signal that invades the sound system via a radio frequency (RF) signal. Definitely "buzz" sound of RFI will ruin your music experience.

Most FM transmitters would work fine when cigarette lighter's voltage outputs under 32V, but in some cases the voltage will spike to 40V like engine starts, battery issue, etc.. with which your device and car is in dangers! Ronxs FM transmitter functions with extra protections. The innovative design in the device, a replaceable fuse tube, can protect your device and car from damaging in the unexpected situations. Be safer!

Ronxs Bluetooth fm transmitter also features an impressive frequency spectrum ranging from 87.5MHz to 108.0MHz. You can play audio through the USB, AUX jack, Bluetooth or straight from the device itself from a MicroSD or TF card.

Live for music, Ronxs!


IMPORTANT TIPS:
This has the "SWITCH OFF/ON" function. You can switch off/on the FM transmitter through long-pressing "SCAN" Button for 3 seconds.
