Garmin GPSMAP 8622 Chartplotter, 22 in Full HD, Navionics+ Charts

Overview

The Garmin 010-01511-50 is a GPSMAP 8622 22-inch class chartplotter with a full HD IPS touchscreen (1920 x 1080) and built-in Garmin Navionics+ inland and coastal mapping for the U.S. and Canada.

It is sized for larger helms, with a housing that measures 20.8 x 13.8 x 2.8 in and a weight of about 15.6 lb. The display is IPX7-rated and runs on 10 to 35 Vdc, with a typical draw of 3.9 A at 12 V (59 W max at 10 Vdc), so it fits 12 V and 24 V systems when wired through your helm distribution.

For networked boats, it brings a lot of connections to the dash: four Garmin Marine Network ports for sharing data between displays and modules, plus NMEA 2000, NMEA 0183, and J1939 for engines, sensors, and legacy integrations.

Key features

• 22-inch class full HD IPS touchscreen (1920 x 1080) with an anti-glare finish that stays easy to read in sun and with polarized sunglasses.
• Power input 10 to 35 Vdc with typical draw of 3.9 A at 12 V and maximum power usage of 59 W at 10 Vdc.
• IPX7 water rating for exposed helm installations.
• Four Garmin Marine Network ports for high-bandwidth sharing across displays, radar, sonar modules, and cameras.
• Network options for mixed systems: NMEA 2000, NMEA 0183, and J1939 connections.
• Video connectivity includes HDMI in, HDMI out, and composite video input for compatible cameras and displays.
• Built-in Garmin Navionics+ coastal charts and inland mapping for the U.S. and Canada, including Auto Guidance+ route suggestions.
• SmartMode and OneHelm support for organizing helm views and managing compatible integrated onboard systems.

Installation and mounting

The unit supports flush mounting or surface mounting. Flush installs are easiest when you plan the cutout location with enough clearance behind the dash for cable bends, locking rings, and service access.

If the mounting spot faces direct sun, leave airflow behind the display and avoid sealing it into a hot, unventilated console. Keeping unused connectors capped helps protect contacts from salt spray and routine washdowns.

Electrical and system integration

Power input is 10 to 35 Vdc. A dedicated nav electronics switch or ignition-fed circuit is common so the display powers down with the rest of the helm equipment, and stable battery connections matter for avoiding reboots when the boat is pounding.

NMEA 2000 is a straightforward path for sensors, autopilot data, and shared PGNs across the boat. NMEA 0183 and J1939 are there when you are tying into older instruments, VHF data, or engine gateways that do not live on NMEA 2000.

Sonar and fishing integration

This part number is the non-sonar chartplotter configuration, so sonar comes from compatible transducers and sonar modules on the network. With the right hardware connected, it can display traditional CHIRP and scanning sonar views and share sonar across networked Garmin displays.

On-the-water use

This display makes sense on boats where you want one large screen at the primary helm and the ability to mirror and share data to other stations. It is a practical fit for bigger center consoles, sportfishers, and cruisers running radar, cameras, engines, and instruments on a single network.
