The Garmin GPS 19x HVS is a high-sensitivity NMEA 0183 position receiver and antenna designed to integrate with Garmin marine instruments, autopilots, and multifunction displays. Its 10 Hz update rate delivers position, velocity, and time data up to ten times more frequently than standard receivers, producing a smoother chartplotter track at all speeds — including slow trolling and tight turns where lesser units tend to jitter or skip.

Specifications:

• 32-channel receiver supports GPS, GLONASS, Galileo¹, and QZSS¹
• Update rates: selectable 1 Hz, 5 Hz, or 10 Hz for position, velocity, and time
• WAAS-capable position accuracy to within 3 m (9.84 ft)
• High-sensitivity reception with enhanced position acquisition
• Smooth, consistent heading output — especially effective at low speeds and through turns
• Eliminates position skipping during low-speed operation and arc turns
• Waterproof rating: IPX7
• Mounting options: pole mount, flush mount, or underside of fiberglass deck
• Compatible with Garmin marine instruments, autopilots, and MFDs; GPSMAP 6000/7000 series and newer chartplotters fully optimized for 10 Hz data
• Interface: NMEA 0183

¹ Galileo and QZSS supported when available; a software update may be required.
