I love this FM Transmitter! It works perfectly! The sound quality is great. It is VERY easy to setup. All you have to do is connect your bluetooth on your phone to the bluetooth that comes up when the transmitter is on. Once your phone and the transmitter are paired the transmitter will have a radio station, you then find that radio station and you now have blue tooth in your car! You can do more than listen to music with this FM transmitter. You can also use the transmitter for voice navigation and phone calls. The transmitter has 2 USB ports for charging. The transmitter also has noise reduction to help with music and calls.
