Product Information
The Fusion Apollo MS-RA770 Touchscreen Marine Stereo is a marine head unit with a 4.3-inch touchscreen, built-in Wi-Fi and support for Apple AirPlay 2 streaming. Its 2-ohm capable Class D amplifier is rated at 43 watts RMS x 4 into 2 ohms and 26 watts RMS x 4 into 4 ohms, and Multi-Zone technology controls up to four audio zones.
Each zone can run its own DSP profile, configured in the Garmin Audio app. Garmin lists AM/FM, Bluetooth, AirPlay 2, digital optical input, USB audio, UPnP and two auxiliary inputs among the sources, plus SiriusXM readiness in the U.S. with an optional SiriusXM Connect vehicle tuner. Apollo stereos network over Ethernet or wirelessly, and the NMEA 2000 port allows control from a compatible Garmin chartplotter as well as from a smart device or Garmin watch.
The front panel is rated IPX6 and IPX7 when properly installed, and the unit supports both ERX and NRX wired remotes for additional control stations. Software updates arrive over the air through the Garmin Audio app or by USB.
