GPSMAP® 1623 - 16" chartplotter display

For a flush-mounted installation, use the mounting template provided with the product. If you need to print a template, ensure it is printed at 100% scale and verify the dimensions with a ruler.

The cutout dimensions for the GPSMAP 1623 are 234 mm (9 3/16 in) in height by 375 mm (14 3/4 in) in width. It is recommended to cut along the inside of the template line.

For mounting holes, drill a pilot hole of 3.2 mm (1/8 in) for wood screws, or a 6 mm (1/4 in) hole for a mounting plate. If no mounting plate is used, it is possible to tap threads to M4.

Yes, to connect standard Ethernet devices, such as a network camera, network switch, or PoE injector, to a Garmin Marine Network, a Garmin Power over Ethernet (PoE) isolation coupler (part number 010-10580-10) is required. Connecting a PoE device directly to a Garmin chartplotter will damage the chartplotter and potentially the PoE device.

It is also recommended to use a shielded cable, such as a CAT 5e F/FTP, for better protection of your equipment.

The GPSMAP 1623 offers extended video integration capabilities, enabling superior monitoring of your boat. You can view video on all chartplotter screens on your boat or display multiple video streams on a single combined display.

It supports integration of:

Network cameras: using a Garmin PoE isolation coupler (010-10580-10).Composite video cameras: current GPSMAP chartplotters (excluding some older series) have built-in video encoder functionality that shares connected video via their composite video input across all chartplotter screens.Touch gestures can be used to control the camera from the chartplotter, such as pinching to zoom and swiping to pan and tilt the camera. You can also customize the chartplotter to store on-screen presets for each camera, including position and zoom data.

Yes, the GPSMAP 1623 is compatible with FLIR thermal cameras. Marine FLIR cameras provide thermal imaging and may offer a low-light camera output as an option.

When you connect a FLIR camera to your compatible chartplotter, the network automatically detects the camera and displays it in the source list without requiring pre-configuration before installation.

Note that FLIR MD-series cameras provide only thermal views, while FLIR M-series dual-payload cameras can switch between thermal and visible views.

When the GPSMAP 1623 is connected to the appropriate cameras and sensors, it supports several camera tracking features:

Compass Lock: to keep the camera fixed on a compass heading.Vessel Lock: to lock the camera at a fixed angle relative to the vessel.Slew-to-cue: to track AIS targets, MARPA targets, or waypoints.To use these functions, you must connect a compatible marine camera with tracking capability (such as a newer FLIR IP video camera), a GPS antenna, and a heading sensor (ideally a 9-axis sensor for optimal performance) to the Garmin marine network or NMEA 2000 network. For AIS and MARPA tracking, a compatible AIS receiver and a compatible radar device are also required.

For optimal network performance, Garmin recommends not streaming more than five video sources simultaneously on the Garmin marine network.

The GPSMAP 1623 can be configured to display multiple videos at once on combined displays. However, on devices with multiple composite video inputs, only one video function within a combined display can use an integrated video input.

The Garmin GPSMAP 1623, as a non-aviation product, is warranted against defects in materials or workmanship for a period of one year from the date of purchase. During this period, Garmin will repair or replace, at its sole discretion, any defective component under normal use, free of charge to the customer for parts or labor. The customer is responsible for shipping costs.

The limited warranty for the GPSMAP 1623 does not apply in several situations, including:

Cosmetic damage such as scratches, nicks, and dents.Consumable parts, like batteries, unless the product damage is due to a defect in materials or workmanship.Damage caused by an accident, abuse, misuse, water, flood, fire, or other natural disasters or external causes.Damage caused by service performed by anyone other than an authorized Garmin service provider.Damage caused by modifying the product without Garmin’s written authorization.It is important to refer to the printed manual provided with the product for all detailed warranty conditions and exclusions.

For a flush-mount installation of the GPSMAP 1623, the mounting template specifies a cutout of 375 mm (14 3/4 inches) wide by 234 mm (9 3/16 inches) high. These dimensions must be strictly adhered to for proper fitment.

Yes, the GPSMAP 1623 is supplied with its mounting template. It is strongly recommended to use the template provided in the product box rather than printing your own, to ensure precise dimensions for cutting.

To connect standard Ethernet devices to a Garmin marine network, use a shielded cable, such as a CAT 5e F/FTP. This type of cable provides the best protection for your equipment and ensures optimal network performance.

The GPSMAP 1623 is designed for extended video integration and is compatible with network cameras and composite video cameras. It supports integration of third-party cameras, including FLIR cameras from the M and MD series. FLIR IP cameras are automatically detected by the Garmin marine network without prior configuration.

Yes, a Garmin Power over Ethernet (PoE) isolation coupler (part number 010-10580-10) is required to connect any standard Ethernet device (such as a network camera, network switch, or PoE injector) to a Garmin marine network. Directly connecting a PoE device to a Garmin chartplotter will damage the chartplotter.

The GPSMAP 1623 offers extended video integration capabilities. It allows you to display network and composite camera video on all chartplotter screens on board. You can also display multiple video streams simultaneously on a single multifunction display. Current GPSMAP chartplotters feature a built-in video encoder to share composite video inputs across the entire network.

To ensure optimal network performance, Garmin recommends not streaming more than five video sources simultaneously over the marine network.

You can control compatible cameras directly from the touchscreen of your GPSMAP 1623 chartplotter. This includes using touch gestures to zoom, pan, and tilt the camera. It is also possible to customize your chartplotter to store presets, such as camera position and zoom data, for each camera.

The camera follow function allows the GPSMAP 1623 to automatically control the direction of certain cameras. It offers several modes:

Compass Lock: keeps the camera fixed on a heading.Vessel Lock: locks the camera at a fixed angle relative to your vessel.Slew-to-cue: allows tracking AIS targets, MARPA targets, or waypoints.

To use the camera tracking function, you must connect specific equipment to the Garmin marine or NMEA 2000 network:

A marine camera compatible with tracking (e.g., a newer FLIR IP video camera). A GPS antenna. A heading sensor (a 9-axis sensor is recommended for better performance). For AIS target tracking, a compatible AIS receiver is also required. For MARPA tracking, a compatible radar device is necessary.

On FLIR dual-payload camera models, the video output cables are usually labeled V/IR and IR-only:

The V/IR cable provides a video stream that can be switched between daytime video and infrared video, offering increased flexibility. The IR-only cable provides infrared video only. The V/IR stream is recommended if you are connecting only one cable directly to a chartplotter, as it offers more display options.
