Both Apple iPod/iPhone and Android devices are catered for on the KDC-4054UB via its front mounted full speed USB input (Free Android Kenwood Music Control App required). Charging of USB connected devices is helped by the high 1amp maximum output. Mobile MP3 players can also be connected via an illuminated front audio input socket (AUX). A cool blue display gives easy visibility even in sunny conditions. And a high power 4x50watt built-in power amplifier will fill your car with high quality sound from any source.
