FUSION Apollo MS-RA770 Marine Stereo with Built-in WiFi
The FUSION Apollo MS-RA770 is a 4.3-inch touchscreen marine stereo with built-in Wi-Fi, Apple AirPlay 2, and a Fusion-Link Wired NMEA 2000 certified connection — the first marine stereo to combine a touchscreen with onboard Wi-Fi audio streaming. Marine technicians and boat owners install the unit at helm dash positions on power and sail vessels requiring multi-zone audio control.

Compatibility & Applications
- Wires to NMEA 2000 networks as a Fusion-Link certified product for MFD audio control.
- Pairs with compatible Garmin chartplotters and fishfinders for on-screen track and volume management.
- Connects to Fusion NRX series wired remote controls over a powered NMEA 2000 network for zone-level control.
- Pairs wirelessly with additional Fusion PartyBus-enabled stereos for synchronized multi-unit audio across a vessel.
- Mounts flush at helm dash positions on center consoles, sportfish boats, sailboats, and yachts requiring a front-panel installation.
- Accepts SiriusXM via optional Connect vehicle tuner (USA), DAB+ (Europe and Australia), AM/FM, USB, AUX ×2, digital optical, UPnP, and MTP sources.
When connected to a NMEA 2000 network with a speed sensor, the MS-RA770 automatically adjusts output volume relative to vessel speed using speed over ground, speed through water, engine RPM, or wind speed as the source signal — a hardware-level integration not present on non-networked marine stereos. The front panel carries both IPX6 and IPX7 ratings and has been tested against salt fog, UV, temperature variation, and vibration.
