Know before you buy
The MS-WB670 is a compact, box-style unit designed to be mounted out of sight, such as behind the dash or in a storage compartment. This keeps your helm clean and uncluttered while still providing full audio control through your existing Garmin MFD or a compatible wired remote.
Yes, the unit supports up to three independent audio zones. This allows you to adjust volume levels or audio sources for different areas, such as the cockpit, cabin, and swim platform, individually.
You do not need a dedicated remote if you already have a compatible Garmin Multi-Function Display (MFD), as the stereo integrates directly with the interface. If you prefer a physical control point, you can also connect a Fusion wired remote to the system.
The built-in DSP automatically optimizes the audio signal based on your specific Fusion speakers and the environment. It helps deliver a clearer, higher-quality sound by minimizing distortion and tailoring the output to your boat's acoustic profile.
Yes, you can stream high-quality audio via Apple AirPlay 2, provided the stereo is connected to a Wi-Fi network through an external router. This allows for a seamless, high-fidelity wireless listening experience from your Apple devices.
The MS-WB670 features a True-Marine design, meaning it is specifically engineered to withstand harsh marine conditions, including exposure to salt, humidity, and UV rays.
