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.

• 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.
• 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.
• 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.
