Garmin marine electronics. Installed right.
NMEA Certified MEI installer serving Nassau County and Suffolk County marinas. GPSMAP, ECHOMAP, Panoptix LiveScope, GMR Fantom radar, and Garmin Reactor autopilot.
We’ve installed Garmin on everything from 20-foot center consoles to 50-foot sportfishers across Long Island. Every install is wired to ABYC E-11 electrical standards on a properly built NMEA 2000 network backbone.
Our process starts with a dock-side consultation where we look at your existing electronics, assess your helm layout, and discuss what you want the system to do. We quote it in writing before any work begins. Installation day runs from rigging transducer cables and mounting displays to programming the network and validating every device from the helm. We don’t consider a job done until the system works exactly the way you expected it to.

Garmin equipment — installed and integrated on Long Island boats.
Garmin builds the most intuitive marine electronics on the market. Pair Garmin hardware with a proper NMEA 2000 network and you get a helm where chartplotter, sonar, radar, autopilot, and VHF all communicate on a single backbone. We handle the full installation — hardware sourcing, mounting, wiring, network configuration, and on-water testing.
A common mistake is buying Garmin hardware at a big box store and trying to wire it yourself. What you end up with is usually a display that works in isolation but nothing talks to anything else. No radar overlay on the chartplotter. Autopilot can’t follow a route. Engine data showing on one screen but not the other. We build the system correctly from the start so every device sees every other device on the network.
After the installation, we walk you through the system at the helm. How to use the chartplotter, how to pair your phone with ActiveCaptain, how to access sonar modes, and how to set up the autopilot are all covered on site. We don’t disappear once the work is done.

Current Garmin screens we install.
Garmin’s 2024–2025 marine display lineup spans entry-level combo units to 27-inch 4K flagship chartplotters. We install across the full range.
GPSMAP x3 Series
GPSMAP 7x3, 9x3, 12x3, 15x3, 16x3 — sunlight-readable touchscreen MFDs with built-in Navionics+, sonar support, and NMEA 2000 networking. The workhorse of Long Island boat helms.
GPSMAP 9000 Series — 4K Flagship
GPSMAP 9219, 9222, 9224, 9227 — large-format 4K resolution displays from 19 to 27 inches designed for glass helm builds on larger sportfishers and motor yachts. The GPSMAP 9500xsv black box extends 4K to third-party monitors. These are the most capable Garmin chartplotters we install.
ECHOMAP UHD2 & Ultra 2
ECHOMAP UHD2 5", 6", 7", 9" — ECHOMAP Ultra 2 12" and 16" — integrated sonar and chartplotter combos with Navionics+ and LiveScope support. The ECHOMAP Ultra 2 supports Panoptix LiveScope Plus and is the most popular mid-range install on Long Island fishing boats.

Why so many Long Island boat owners choose Garmin.
Panoptix LiveScope
The most requested upgrade we install on Long Island fishing boats. Panoptix LiveScope shows live, real-time images of fish and structure around your hull. Requires a compatible GPSMAP chartplotter, transducer mount, and proper NMEA 2000 network. We handle all of it including on-water calibration.
Garmin Marine Network
Garmin devices share data over a single ethernet cable using Garmin Marine Network — reducing NMEA 2000 backbone load and enabling sonar sharing across multiple displays. Install one transducer, view sonar on every screen.
ClearVü, SideVü & CHIRP
ClearVü and SideVü provide near-photographic underwater images from below and to the sides of your hull. CHIRP traditional sonar delivers superior target separation at depth. For offshore fishing on Long Island, this combination finds structure and marks fish better than any previous sonar technology.
GMR Fantom Radar
Garmin’s GMR Fantom solid-state radar uses MotionScope Doppler technology to detect and highlight moving targets in real time — separating buoys from other boats at a glance. The Fantom 18x and 24x are the most common radar installs we do on Long Island center consoles and sportfishers. For larger open-array installs we spec the Fantom 54 depending on range requirements and tower mount options.
Garmin Reactor Autopilot
The Garmin Reactor 40 autopilot integrates directly with any GPSMAP chartplotter via NMEA 2000. Route follow, pattern steering, and heading hold all available from the helm touchscreen. We install the full system including shadow drive for manual override.
NMEA 2000 Integration
Garmin devices are fully NMEA 2000 compatible and integrate with Simrad, Raymarine, Standard Horizon, and other brands on the same network. We build the backbone, add T-connectors properly, terminate both ends, and verify every device is communicating before we leave the marina. If you already have a partial NMEA 2000 network from a previous install, we can audit and expand it to accommodate new Garmin devices without starting over.
What Long Island boat owners say about LIME.
Perfect 5-star rating on Google. Every review is a real customer from a real Long Island marina.
★★★★★
LIME did a full Garmin helm build on my 307. NMEA 2000 network, Panoptix sonar, Halo radar, and autopilot. Flawless installation. Everything talks to everything. 5 stars without question.
— Mike T., Grady-White 307
★★★★★
Had another "installer" mess up my electronics. LIME came in, diagnosed the wiring nightmare, fixed it correctly, and upgraded the whole helm. These guys know what they're doing.
— Rich S., Contender 39 ST
★★★★★
Best in the business on Long Island. NMEA certified, professional, and the cleanest wiring I've ever seen. Worth every penny.
— Dave F., Regulator 31
Frequently Asked Questions
Can you install Garmin Panoptix LiveScope on my fishing boat?
Yes. Panoptix LiveScope installation requires a compatible GPSMAP chartplotter (9x3, 12x3, or ECHOMAP Ultra 2), the LiveScope transducer, a mounting pole or trolling motor bracket, and NMEA 2000 network integration. We handle the full install including on-water calibration to confirm image quality.
What is the difference between the GPSMAP x3 series and the GPSMAP 9000 series?
The GPSMAP x3 series (9x3, 12x3, 16x3) are the standard MFD line — touchscreen, full-featured, 7 to 16 inches. The GPSMAP 9000 series (9219 through 9227) are large-format 4K flagship displays from 19 to 27 inches designed for larger vessels and glass helm builds.
Can Garmin integrate with my existing Simrad or Raymarine equipment?
Yes, via NMEA 2000. Garmin devices are fully NMEA 2000 compatible and share data with Simrad, Raymarine, and Standard Horizon equipment on the same backbone. We verify cross-brand compatibility before any install.
Are you an authorized Garmin installer on Long Island?
We source Garmin products through authorized channels and install to Garmin’s published standards. As NMEA Certified MEI and ABYC E-11 certified installers, we are the most credentialed Garmin installer serving Nassau County and Suffolk County marinas.
How long does a Garmin chartplotter installation take?
A single chartplotter swap on an existing NMEA 2000 network is typically a half-day job. A full helm build — new displays, radar, sonar, autopilot, and AIS — usually runs one to two full days depending on vessel size and wiring complexity. We give you a realistic time estimate during the quote so you can plan around your season.
Do you install Garmin on boats kept at marinas in Nassau and Suffolk County?
Yes. We are fully mobile and work at marinas throughout Nassau County and Suffolk County including Freeport, Amityville, Babylon, Bay Shore, Patchogue, Port Jefferson, and Greenport. We come to your slip. You don’t need to haul the boat or move it to a shop.
What does a Garmin NMEA 2000 network installation include?
A proper NMEA 2000 network install includes a certified backbone cable, powered drop cables for each device, T-connectors, and terminating resistors at both ends. We route cables through the vessel neatly, label every connection, and test communication between every device before signing off. Engine gateways, wind, depth, and heading sensors are all added to the backbone as needed.
Can you upgrade my old Garmin chartplotter to a current model?
Yes. Upgrading from an older GPSMAP or ECHOMAP to a current x3 or ECHOMAP UHD2 is one of the most common jobs we do. In most cases the existing NMEA 2000 network and transducers can stay in place. We assess the existing install, identify what needs updating, and give you a clear upgrade path with pricing before any work begins.
