The Fusion Apollo MS-RA670 Marine Stereo is a compact Apollo Series head unit with a color LCD, built-in Digital Signal Processing and a 2-ohm capable Class D amplifier rated at 43 watts RMS x 4 into 2 ohms or 26 watts RMS x 4 into 4 ohms. Multi-Zone technology controls three separate audio zones, each with its own DSP profile set up in the Garmin Audio app.
Garmin lists AM/FM, Bluetooth, digital optical input, USB audio, UPnP and an auxiliary input among its sources, along with SiriusXM readiness in the U.S. with an optional SiriusXM Connect vehicle tuner. Ethernet joins it to other Apollo stereos on a wired network, and the NMEA 2000 port allows control from a compatible Garmin chartplotter; a smart device or Garmin watch can also control it, and it supports ERX and NRX wired remotes.
The front panel is rated IPX6 and IPX7 when properly installed, and the unit is built to Fusion's True-Marine standard for salt fog, temperature, vibration and UV. Software updates are delivered over the air through the Garmin Audio app or by USB.
