HIGH-RESOLUTION AUDIO
Our first marine stereo to support high-resolution lossless audio, RA800 offers unparalleled sound quality — supported by Wi-Fi technology for seamless audio streaming.

UPGRADED INTERNAL AMP
The built-in Class-D amplifier can deliver 4 x 40 watts RMS (all channels driven) with less than 0.1% total harmonic distortion at 4 ohms — producing more than 50% more power output1 than its predecessor.

HIGHER-RESOLUTION DISPLAY
The stereo's 4.3-inch LCD touchscreen display offers notable improvements1 in image resolution, color saturation, viewing angles and readability in bright daylight.

STEREO NETWORKING
Connect your RA800 stereo with other Apollo Series stereos to create a network on board your boat. Enjoy advanced features, including stereo grouping, combined volume control, power options and Home Zone control.

MULTIPLE SOURCE OPTIONS
Take advantage of a wide variety of source options available, including AirPlay streaming from Apple®, BLUETOOTH® connectivity, HDMI ARC, DAB+ radio tuner, USB connections, AM/FM radio and AUX inputs.

MFD NETWORKING
Easily network your RA800 stereo with a compatible Garmin MFD via NMEA 2000® or Garmin BlueNet™ network for integrated audio control at the helm.
EASY-FIT INSTALLATION
QUICK SWITCH FROM RA770 TO RA800
With an identical form factor as the predecessor RA770, upgrading and installing the RA800 is simple.
ADVANCED AUDIO PERFORMANCE
AUDIO STREAMING WITH WI-FI
Built-in Wi-Fi connectivity for AirPlay audio streaming offers a seamless high-fidelity listening experience.
ONE-PIECE GLASS TOUCH DISPLAY
An intuitive menu-driven interface and edge-to-edge glass touchscreen let you simply tap or swipe the display for easy control of stereo functions.
MODERN DESIGN AND AESTHETICS
The stereo's black glass faceplate can be flush mounted to blend seamlessly with other electronics at the helm.
ENGINEERED FOR HARSH MARINE ENVIRONMENTS
Built on the True-Marine™ design philosophy from Fusion, RA800 has an IPX6- and IPX7-rated water-resistant front panel and has been tested to a high level of protection against salt fog, temperature, vibration and UV exposure.
DIGITAL SIGNAL PROCESSING (DSP)
A technically superior listening experience made simple, Fusion DSP optimizes the audio signal delivered to your system to produce superior sound quality at all volume levels, in every listening environment.
EASY-TO-INSTALL DSP PROFILES
With the free Garmin Audio app on your smartphone, you can set up the preconfigured DSP profiles once and enjoy high-quality audio customized for your listening environment.
A SUPERIOR LISTENING ENVIRONMENT
STEREO GROUPING
Grouping allows you to link up multiple Apollo Series stereos connected to the same network and play the same audio source synchronized across all stereos.
VOLUME CONTROL
Scroll through available zones on your boat, and enjoy independent volume control, or select ALL volume to adjust a group of stereos at once.
POWER OPTIONS
Power options allow you turn on any connected Apollo Series stereo in standby mode on the Fusion stereo network remotely from another Apollo Series stereo.
HOME ZONE
Home Zone is the physical zone in which the stereo is installed on board your boat. After adjusting audio in another zone, the stereo defaults to control of the Home Zone after a period of inactivity.
OVER-THE-AIR SOFTWARE UPDATES
Updates are available from your compatible smartphone or device, via the free Garmin Audio app. See owner's manual for alternative update methods.
SPEED VS. VOLUME
Selecting Speed vs. Volume from the stereo's Settings menu enables audio volume to be automatically adjusted based on your boat's speed2. Faster equals louder; slower equals lower volume.
