Installation

Unpack and inspect contents. Choose mounting location with clear view of sky.

Mount unit: Use provided hardware for flush or rail mounting.
Connect power/data cable: Red wire to +12V DC, Black wire to ground.
Connect to device: Connect NMEA output wires to chartplotter or other NMEA device.
Secure connections: Ensure all connections are waterproof if exposed.

WARNING! Ensure power is off during installation. Mount in location free from obstructions.

First-Time Setup

Power on unit; observe LED status.

Initial acquisition: Allow 5-15 minutes for first satellite fix (cold start).
LED interpretation: Solid green = 3D fix; Blinking green = 2D fix; Red = no fix.
Verify output: Connect to compatible device to confirm NMEA data stream.
Configure output sentences: Use compatible software if needed (default GGA, GSA, GSV, RMC).

CAUTION! Do not power with voltage outside 10-40 VDC range.

Specifications

Receiver Type: 12-channel GPS with WAAS/EGNOS.
Update Rate: 1 Hz standard.
Accuracy: <3 meters RMS with WAAS; <15 meters RMS without WAAS.
Acquisition Times: Cold start ~45 sec; Warm start ~15 sec; Hot start ~1 sec.
Velocity Accuracy: 0.1 knot RMS steady state.
Output Protocol: NMEA 0183 version 3.01.
Power Consumption: 140 mA typical at 12 VDC.
Waterproof: IPX7 standard.
Weight: 85 grams (3.0 oz).

Controls and Connections

Unit has no physical buttons. Status indicated by LED. Cable connections: Power (Red/Black), NMEA Out + (Blue), NMEA Out - (Brown), NMEA In + (Green), NMEA In - (Yellow).

LED Status: Off = No power; Solid Red = Power on, no fix; Blinking Green = 2D fix; Solid Green = 3D fix; Blinking Red = Self-test failure.

Mounting: Use provided screws for permanent installation. Ensure antenna face has clear sky view.

Configuration & Output

Default NMEA 0183 sentences: GGA, GSA, GSV, RMC. Baud rate: 4800 (default).

Connect to configuration software (optional) via serial port.
Adjust output sentences, baud rate, or update rate if required.
Enable/disable WAAS/EGNOS (enabled by default).

Tip: Most marine plotters auto-detect NMEA input; manual configuration may be needed.

Operation & Navigation

Once installed and powered, unit operates automatically.

Power on: LED will illuminate red, then transition to green as fix is acquired.
Monitor status: Solid green LED indicates valid 3D navigation data.
Data output: NMEA sentences stream continuously to connected device.
Cold/warm starts: Unit stores almanac data for faster subsequent acquisitions.
Battery backup: Internal capacitor maintains memory for warm starts (short term).

WARNING! Performance degraded near tall structures, indoors, or under dense canopy.

Maintenance & Care

Periodically check cable connections for corrosion. Clean exterior with fresh water and mild soap if needed.

CAUTION! Do not use high-pressure water spray. Do not disassemble unit.

Regulatory Information

FCC Part 15: Class B digital device. Complies with Canadian ICES-003. CE marked. Contains GPS technology subject to export regulations. For support, visit www.garmin.com or contact Garmin International at 913-397-8200.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No LED illumination	No power	Check power connections and voltage (10-40 VDC).
Solid red LED	No satellite fix	Ensure clear sky view; allow more time for acquisition.
Blinking red LED	Hardware fault	Cycle power; if persistent, contact support.
No data on plotter	Wiring or configuration	Verify NMEA wiring; check plotter input settings (4800 baud, NMEA).
Poor accuracy	WAAS unavailable or obstruction	Relocate for better sky view; WAAS may be unavailable in some regions.

Reset: Disconnect power for 30 seconds to perform cold start.
