PRV250 PackageThis radio features state of the art Bluetooth technology allowing music to wirelessly stream from an audio source to the receiver you just purchased. Why Bluetooth? From a practical standpoint, Bluetooth enables your music device (if applicable) to be placed in a glove box, your overhead console, or even your pocket-places that are dry-without having to install a separate docking station. In addition, Bluetooth audio streaming will work with any Bluetooth enabled device, not just one brand of media. Once connected, you can use your receiver to control your media device and vice versa! Bluetooth has a range of approximately 30', depending upon conditions, so once your boat is parked, feel free to control the stereo through your media device!Stereo Features: Bluetooth Audio Streaming 4 x 50 watts Solid aluminum chassis Aux-in Portable-media ready USB input ASTM117 salt fog 1 pair of RCA outputs IP66 waterproof face 6" (L) x 4" (W) x 2 1/2" (D)WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
