The Apollo RA670 marine stereo inherits key audio innovations and revolutionary technology from the award-winning Apollo RA770, reimagined in a compact form factor.

• Built on the True-Marine design philosophy from Fusion^®, the Apollo RA670 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 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.
