THE SUM OF AUDIO INNOVATION
The world’s first touchscreen marine stereo with the AirPlay® 2 software feature and built-in Wi-Fi® connectivity, Apollo RA770 has redefined audio excellence with revolutionary technology and innovative design.
DESIGNED AND ENGINEERED TO TRUE-MARINE™ STANDARDS
Built on the True-Marine design philosophy from Fusion®, the Apollo RA770 stereo 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.
MODERN DESIGN AND AESTHETICS
Providing uniformity across the helm, the brilliantly designed black front face blends seamlessly into black glass panels, complementing other electronics and MFDs for a tidy, uniform and elegant installation.
SPEED VS. VOLUME
With your stereo connected to an NMEA 2000® network with an appropriate speed sensor installed, selecting Speed vs. Volume from the stereo’s settings menu enables audio volume to be automatically adjusted based on your boat’s speed. Faster = louder; slower = lower volume. Compatible speed sources include speed over ground, speed through water, engine RPM or wind speed.
FUSION DIGITAL SIGNAL PROCESSING (DSP)
A technically superior listening experience made simple, Fusion DSP optimizes the audio signal delivered to your Fusion system to produce superior sound quality at all volume levels, in every listening environment.
EASY-TO-INSTALL DSP PROFILES
With a few clicks on your compatible smartphone, setting up your DSP profiles is made simple with the free Garmin Audio app. You can set up the preconfigured DSP profiles once and enjoy listening to high-quality audio customized for your ears and the environment.
AUDIO STREAMING WITH WI-FI
In a world-first for marine stereos, enjoy the clarity and premium quality of audio streaming with Wi-Fi, including the convenience of AirPlay 2 and universal plug-and-play (UPnP)1.
APOLLO RA770 WITH SRX400
Designed with Wi-Fi onboard, the Apollo RA770 and its perfect companion SRX400 can be connected without running any wires – reducing installation time, cost and complexity.
OVER-THE-AIR SOFTWARE UPDATES
Updates are now available from your compatible smartphone or device, via the free Garmin Audio app. The Apollo Series is intelligently simple and easy to keep up to date1.
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 to turn on any connected Apollo Series stereo in standby mode on the Fusion PartyBus-Network remotely from another Apollo Series stereo.
HOME ZONE
Home Zone is the physical zone on board your boat in which the stereo is installed. After adjusting audio in another zone, the stereo defaults to control of the Home Zone after a period of inactivity.
ONE-PIECE GLASS TOUCH DISPLAY
The premium glass touchscreen display is beautiful edge-to-edge. Simply tap or swipe the screen for stereo control without the hassle of trying to locate the right button.
