The Sony CDX-GT610UI has a built-in generic USB port, enabling drivers to take their digital music on the road without the need for a separate MP3 player. It also comes with a built-in iPod dock connector and a generic auxiliary-input jack, making it one of the most adaptable single-DIN in-car stereo receivers currently on the market. The CDX-GT610UI plays a range of disc-based digital audio formats, including MP3, WMA and ATRAC discs, as well as regular Red Book CDs. And, of course, it picks up AM and FM radio signals.
