I received the Wireless FM Radio Transmitter/Bluetooth a couple of days ago and it is working Great! I had to re-watch the sales video that Zach had done before I was able to get it working, but am very pleased with it. You have to finely tune in an FM station on the car radio, and then tune in that channel on the FM Transmitter. I like to run audio books on my iPhone 6 Plus, so I had to pair my iPhone up with the FM Transmitter. Now, when I go out to my car and start it, with the FM Transmitter already plugged into the cigarette lighter, I will hear a beep when the iPhone and FMT reconnect, and then the story will continue from where I left off, and this only takes a few seconds. I do have to turn the volume up a bit on my car radio, and when I turn the car off, and thus the audio book, the radio is too loud until I unplug the car key. All in all, though, I am very happy with it. I was tired of having to mess around with an auxiliary cord that would go bad and have to be replaced periodically, had to be plugged in and out of the phone all the time, and then pull up the audio book again. It is right there instantly with this unit. Very nice!
