It’s not wireless so there’s no interference. Not to be confused with an FM transmitter. Basically it adds an AUX input to ANY radio. No searching for a clean channel.

It feeds your audio signal from a headphone jack ( or RCA cables) by FM modulation, directly into the antenna input on your radio bypassing the antenna when on, allowing the radio to work as normal when off. It comes with an On/Off switch.

The best FM Modulator I’ve ever heard (and now I have it) is a model from Monstor Cable. Mine charges as well, and has 3 presets for quick changes in different locations. But as said above, FM Modulation is not the best.
