## Description

BOSS Audio Systems MGV520B Marine Gauge Receiver – Weatherproof, 3 Inch LCD, Built-in Amplifier, Bluetooth, Digital Media MP3 Player, No CD Player, USB Port, AM/FM Radio

Review: Good craftsmanship!! - Sounds great and easy to install! Has been on the boat for 3 years now and still working great!
Review: Perfect head unit for UTV's! - I installed the BOSS MGV520B in my Polaris Ranger, and it has been a fantastic addition. The sound quality is clear and loud enough to hear over engine noise, and the built-in amplifier provides plenty of power for my setup. Bluetooth connects quickly and streams music without issues, and the AM/FM reception is solid. The weatherproof design is perfect for off-road conditions—I’ve used it in dusty and wet environments without any problems. The 3-inch LCD screen is easy to read, even in bright sunlight, and the controls are straightforward. Overall, this is an excellent choice for anyone looking to upgrade their UTV’s audio system. Highly recommended!

### ⭐⭐⭐⭐⭐ Great features and amplifier!
*by J***N on March 18, 2026*

I needed a unit for my Duffy Boat that had enough power to push my speakers without using an external amplifier and the Boss unit was perfect! Great sound with crisp highs, mids, and lows… and an abundance of features: front and rear camera inputs, subwoofer output, etc! It connects to my Bluetooth before I even step aboard! Very pleased!
