This radio features 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, making this a practical solution for boats VTVs, and more! The PRV-175 incorporates the following features: AM/FM/Bluetooth Audio Streaming, USB input, auxiliary input, waterproof faceplate, 45W x 4 amplifier, RF remote/wired remote option, United States and European tuning, charging through USB and 2 pairs of RCA outputs. The JBL-PRV175 model only includes the stereo and RCA outputs.
