The BOSS Audio Systems MGV520B is a solid choice for a marine stereo head unit if you want a weatherproof and versatile system without a CD player.

The 3-inch touchscreen is easy to see and control, though it’s on the smaller side compared to some modern units. Power-wise, it offers 60 watts per channel across four channels, giving enough volume and clarity for typical boat speakers or a subwoofer setup.

Installation is recommended to be professional to ensure weatherproofing and performance. The included 3-year warranty through Amazon adds peace of mind. This unit works well for boaters wanting a reliable, weather-resistant stereo with modern wireless features, but it might feel basic for those looking for larger displays or more advanced connectivity.
