The XO BCC17 transmitter is a very useful device for any driver who does not have USB or AUX. With a transmitter in the car, you don't have to worry about your phone charger being empty, as you can charge it quickly through the USB ports. With this product, you can also play music from your phone or USB. It also supports answering and rejecting calls, reconnecting with the last number, changing frequency, managing tracks, and adjusting volume, all from one transmitter.
