Grantwood Technology has announced the FM Transmitter, which allows you to play any audio on your mobile device through your car stereo.
You can play music from your personal collection, audiobooks from Amazon, and streaming audio from apps like Pandora and Spotify. FM Transmitter is compatible with any device with a standard headphone jack, including iOS and Android devices. It also contains a USB port to allow you to charge the same device that is playing the audio, or charge a second device.
For the initial launch, the FM Transmitter is available online on Amazon and at the Grantwood Technology website (http://tinyurl.com/oh28hso) for US$29.99. Later this year it will be available at traditional retail locations.
