The XT is currently the smallest XM Satellite Radio receiver, however, in order to use the device it must be hooked up to either car/home audio system. Measuring in at 3.7�?W x 2.25�?H x 0.615�?D, it weighs only 2.8 ounces and can transmit to any FM radio within 20 feet.
Bar the fact that the Delphy requires plug and play connectivity, doesn’t support recording or rewind, and cannot match the sound quality of in-car FM radio, it is still mighty small and quite good looking.
