This multimedia receiver packs a lot of features into a compact design. You'll enjoy AM/FM radio, of course, plus built-in Bluetooth® that lets you stream music from your smartphone. You can also use the rear aux input for your music player, or plug a thumb drive into the rear USB port to enjoy your favorite music.The PRV-175 features a set of rear-mounted preamp outputs, so you can expand your system with a marine amp in the future. The LCD display lets you see what you're listening to with just a glance, while the watertight, UV-stable face and controls will stand up to sun, salt and moisture when you're riding the waves.
