Garmin Fusion Apollo MS-RA670 Marine Stereo with DSP


Description

The Fusion Apollo MS-RA670 is a premium marine stereo that brings award-winning audio technology to a compact, helm-ready form factor. Inheriting key innovations from the flagship Apollo RA770, this stereo delivers superior sound quality through built-in Digital Signal Processing (DSP), Wi-Fi audio streaming via Apple AirPlay 2, and Bluetooth connectivity. Designed to True-Marine standards, the RA670 features an IPX6 and IPX7 rated front panel that resists water, salt, fog, UV, and vibration for lasting durability on the water.

Whether you're managing a single zone or coordinating audio across an entire vessel with Multi-Zone Technology and Fusion PartyBus-Network, the RA670 gives you complete, effortless control. Pair it with a compatible Garmin multifunction display (MFD), a smart device, or even a compatible Garmin watch to keep your music at your fingertips no matter where you are on the boat.


Key Features

  • Built-in DSP (Digital Signal Processing): Optimizes audio output at every volume level for a superior listening experience in any marine environment.
  • Apple AirPlay 2 Support: Stream high-quality audio wirelessly from compatible Apple devices to multiple Apollo Series stereos on the same network.
  • Wi-Fi Audio Streaming via Ethernet: Connect via Ethernet to a wireless router or Garmin MFD for Wi-Fi streaming, over-the-air updates, AirPlay 2, and UPnP support.
  • Multi-Zone Technology - 3 Zones: Control up to three independent audio zones on your boat with individual volume settings or group-wide control.
  • Fusion PartyBus-Network: Link multiple Apollo Series stereos on the same network and synchronize audio playback across the entire vessel.
  • True-Marine Construction (IPX6/IPX7): Front panel is rated for water resistance and tested against salt, fog, UV, temperature extremes, and vibration.
  • Speed vs. Volume (NMEA 2000): Automatically adjusts volume based on boat speed when connected to an NMEA 2000 network with a compatible speed sensor.
  • Wide Source Compatibility: Supports AM/FM, Bluetooth, Apple AirPlay 2, optical audio, USB, AUX, UPnP, SiriusXM-Ready, and DAB+ ready.
  • 280W Peak Power / 43W RMS x4: Delivers strong, clean amplified power to four speaker channels with three RCA pre-out zones for external amplification.
  • Garmin Watch & MFD Control: Compatible with Garmin quatix watches and a wide range of ECHOMAP and GPSMAP multifunction displays for seamless helm integration.

Display Options & Which to Choose

  • Touchscreen LCD: Features a full color touchscreen LCD for intuitive, direct on-unit control of sources, zones, and settings. Ideal for boaters who prefer a standalone, easy-to-navigate interface without relying on an external device or MFD.
  • Color LCD (No Touchscreen): Provides a color display for at-a-glance information at a lower price point. Best for users who plan to control the stereo primarily through a Garmin MFD, smartphone app, or compatible Garmin watch.

FAQ

Does the RA670 require a Wi-Fi router to use AirPlay 2?

Yes, Wi-Fi-dependent features like AirPlay 2 and over-the-air software updates require the stereo to be connected via Ethernet to a wireless network router (sold separately), a compatible Garmin MFD, or an Apollo Series stereo network with Wi-Fi capability. Bluetooth streaming does not require a router and works independently.

What is the difference between the Touchscreen LCD and Color LCD display options?

The Touchscreen LCD model allows you to control the stereo directly on the unit via a responsive touch interface. The Color LCD model displays information on screen but is primarily controlled through a connected Garmin MFD, the Fusion Audio smartphone app, or a compatible Garmin watch. If you plan to integrate the stereo into an existing Garmin MFD setup, either option works well - the Color LCD may offer better value.

Can I control this stereo from my Garmin chartplotter or MFD?

Yes. The MS-RA670 is compatible with a wide range of Garmin ECHOMAP and GPSMAP multifunction displays via the Fusion-Link wired technology over NMEA 2000. This allows full audio control - source selection, volume, zone management - directly from the MFD screen at the helm.

Is the RA670 compatible with SiriusXM satellite radio?

Yes, the RA670 is SiriusXM-Ready. To receive SiriusXM satellite radio, you will need an optional SiriusXM Connect vehicle tuner (sold separately). SiriusXM service is available in the U.S. only and includes advanced features like on-screen album art.

How many speakers or amplifier zones can I run with the RA670?

The RA670 supports up to 4 speaker connections (2 amplified zones) directly from the unit. It also provides 3 RCA pre-out zones (left, right, and subwoofer per zone) for connecting external amplifiers, giving you the flexibility to expand your system significantly across the entire vessel.

What does Fusion PartyBus-Network do?

PartyBus-Network lets you link multiple Apollo Series stereos together on the same network and synchronize the same audio source across all of them simultaneously. You can also control power states and volume across connected stereos remotely, making it ideal for larger boats where you want consistent audio in every area - cockpit, cabin, and swim platform.
