Top-of-the-line Garmin glass bridge display. The 22-inch GPSMAP 8622 puts a massive, sharp, sunlight-readable chart in front of the helm with Navionics+ charts preloaded, ActiveCaptain integration, and the full Garmin marine networking ecosystem behind it.
The Garmin GPSMAP 8622 (MPN 010-01511-50) is a 22-inch premium chartplotter that sits at the top of Garmin’s flagship marine display line. The 22-inch display is the largest Garmin offers in this product family, sized for serious cruising and commercial bridges where the chart needs to be readable at a glance from anywhere at the helm. The screen is sunlight-readable, full-HD resolution, multi-touch capable, and edge-to-edge glass for a clean glass-bridge install. Garmin Navionics+ charts come preloaded covering coastal North American waters with current chart data and the ActiveCaptain community-sourced point-of-interest layer built in.
What this display delivers. Sharp, immediate chart visibility at long glance distance from anywhere on the bridge. Full multi-touch zoom and pan that feels like a modern tablet, not a chartplotter from a decade ago. Split-screen capability that lets you run chart plus sonar, chart plus radar, chart plus engine data, or any other combination side-by-side without losing legibility on either pane. For owners running a complete Garmin marine electronics ecosystem (radar, sonar, autopilot, engine integration, AIS, weather), the 8622 is the bridge display that ties it all together.
Why this size. For boats in the 50-foot+ range with a serious cruising helm, the 22-inch display isn’t oversized – it’s right-sized. At normal helm seating distances, a smaller display forces you to lean forward to read chart details. The 8622 stays readable from anywhere at the helm, which means you can plan ahead, scan for hazards, and stay aware of your situation without breaking your normal driving posture. For cruising owners who spend long hours at the helm, the difference in fatigue level between a 9-inch display and a 22-inch display is substantial.
Garmin Navionics+ charts. Preloaded charts cover coastal North American waters with the current Garmin Navionics+ data set, including bathymetry, navaids, marina detail, points of interest, ActiveCaptain reviews and tips, and integrated tide and current information. The Navionics+ data is updated regularly through Garmin’s chart update service for owners who maintain a subscription. For waters outside the preloaded region, additional Garmin chart products are available as SD card add-ons.
ActiveCaptain integration. The Garmin ActiveCaptain ecosystem layers community-sourced data over the chart: marina reviews, anchorage notes, hazard warnings, fuel prices, and similar crowdsourced cruising knowledge. For owners cruising unfamiliar waters or planning long passages, ActiveCaptain is a genuinely useful information layer that supplements the official chart data with operational know-how from other cruisers.
Network integration. The 8622 supports Garmin Marine Network connectivity for full integration with Garmin radar (GMR series), sonar (CHIRP, ClearVu, SideVu, LiveScope, Panoptix), autopilot (Reactor, Force trolling motor integration), AIS receivers/transponders, engine data through NMEA 2000, weather receivers, and the full ecosystem of compatible Garmin marine electronics. For owners building a complete Garmin glass bridge, the 8622 is the centerpiece display.
Installation. The 22-inch display is a significant install. Plan flush mount in the helm or dash with proper structural support behind the cutout, professional cable runs for power and network, and integration with the boat’s electrical and grounding systems. The work is straightforward for a marine electronics installer but not a casual DIY project unless you have experience with large flush-mount installs. Professional install protects warranty coverage and ensures proper performance.
Why pay this much. The 8622 is the top of the Garmin chartplotter line, and that position commands a premium over smaller displays in the same family. The premium pays for the display size, the resolution, the brightness for sunlight readability, the glass-bridge build quality, and the integration with the full Garmin ecosystem. For owners who are committed to Garmin and want the largest, brightest, sharpest display in the line, the 8622 is the answer. For owners with smaller boats or simpler requirements, the smaller GPSMAP displays serve well at much lower cost.
