Your phone sends audio to this device over Bluetooth, which is fine. The device then converts it and broadcasts it into the air as an analogue FM radio signal. Your car radio picks that up the same way it picks up any station, with the same aerial and the same tuner.\u003c\/p\u003e\n\u003cp\u003eThat last hop is the limiting one. FM broadcast is band-limited by design and it is open to interference from everything around it, which is why radio has always had a texture that a cable does not. No transmitter, at any price, gets round that, because the physics belong to the radio in your dashboard rather than to the box in your lighter socket.\u003c\/p\u003e\n\u003cp\u003eSo expect a clean, listenable FM station. Do not expect the top and bottom of the range you hear through headphones. If that trade sounds acceptable for getting podcasts and playlists into a car that currently gets neither, this is the right thing to buy.
