Pachet de pornire cablat GMI™ 52

The Garmin GMI™ 52 wired starter pack is a complete solution designed for the digital instrumentation of your vessel. It allows you to set up or expand a NMEA 2000 network, providing centralized display of the boat’s critical data. It is ideal for owners of small sailboats or motorboats looking to modernize their analog system.

The GMI 20 instrument can display a wide range of marine data, including:

Water-referenced speed (COG/SOG)
Water depth
Wind data (direction, speed)
Vessel heading
GNSS position
System time
Engine parameters (fast and dynamic updates)
Battery status
Environmental data (temperature)
Navigation information (course error, route data, and waypoints)

The GMI 20 display dimensions are as follows:

Without sunshade: 110 x 115 x 30 mm (height x width x depth)
With sunshade: 115 x 120 x 35.5 mm (height x width x depth)

The GMI 20 instrument is rated IEC 60529 IPX7. This means it can withstand accidental immersion in water up to 1 meter deep for a maximum of 30 minutes.

The weight of the GMI 20 instrument is 247 g without the sunshade and 283 g with the sunshade.

The GMI 20 instrument housing is made of fully watertight polycarbonate. The lens is glass with an anti-reflective finish.

No, damage caused by extreme temperatures, as well as their consequences, is not covered by the GMI 20 instrument warranty. It is essential to comply with the specified operating temperature range, which is -15°C to 70°C (5°F to 158°F), for both storage and use of the device.

The GMI 20 instrument is designed for flush mounting in the dashboard. A mounting template and the necessary hardware are included in the pack to facilitate this installation.

Yes, when installing the instrument in fiberglass, it is recommended to use a countersink drill bit to drill a relief pilot hole through the gelcoat layer only. This helps prevent cracking of the gelcoat when tightening the screws. It is also advisable to use an anti-seize lubricant when securing the screws.

Yes, it is recommended to place the supplied sealing gasket at the rear of the device and apply marine sealant around the gasket to prevent any water infiltration behind the dashboard.

The GMI 20 instrument connects to your boat's NMEA 2000 network. This network provides power and data from other NMEA 2000 devices, such as wind sensors. The pack includes the necessary NMEA 2000 cables and connectors to connect it to an existing network or to create a basic NMEA 2000 network.

The NMEA 2000 power cable must be connected to the boat's ignition switch or via another inline switch. It must not be connected directly to the battery, as NMEA 2000 devices can drain the battery if power is not cut.

To avoid any interference with a magnetic compass, the GMI 20 instrument must not be installed closer to a compass than the specified safety distance, which is 209 mm.

To prevent corrosion of metal contacts, it is important to cover unused connectors with the provided protective caps.

The GMI 20 instrument can receive NMEA 0183 data from a single device via an NMEA data cable (not included). However, it cannot transmit this NMEA 0183 data to the NMEA 2000 network. To display NMEA 0183 data from sources connected to a GNX™ 20 or GNX 21 device (sold separately), these devices must be on the same NMEA 2000 network.

Yes, the GMI 20 instrument can receive NMEA 0183 sensor data, but this requires an optional NMEA 0183 data cable (not included). Note that the instrument will not retransmit this NMEA 0183 data over the NMEA 2000 network.

Yes, the GMI 20 instrument can receive data from Nexus® instruments and sensors using a GND™ 10 device (sold separately).

A NMEA 2000 power isolator (part number 010-11580-00) is recommended in installations where the manufacturer of the existing NMEA 2000 network is unknown. This ensures proper network operation.

Yes, if you will not have access to the back of the device after installation, it is mandatory to connect all necessary cables to the GMI 20 instrument before placing it in the dashboard cutout.
