The freqOUT pro™ allows you to play music through your car stereo from your iPod or iPhone. The innovative design of the freqOUT pro™ lets you charge your device while you play music through the USB interface. This digital FM transmitter plugs directly into the bottom dock of your iPod or iPhone with your charge & sync cable to provide a clear and crisp audio signal. For devices without a Lightning™ dock, use the included aux cable to plug directly into any headphone jack. The transmitter is powered through any 12v power socket in your vehicle and provides a USB charging port. Plugging in your charge & sync cable is now easy with a glowing USB port. Integrated scanFREQ technology can be easily activated to help you find the best frequency to transmit your music through. Store your frequently used stations into the programmable memory of the freqOUT. The flex-neck design gives you the freedom to position the freqOUT at multiple viewing angles. An easy to read interface displays artist and song title along with the current radio station through which you are transmitting. The freqOUT will even display song information on compatible RDS radios.
