Garmin Marine Accessories

A Garmin chartplotter or sounder is only as good as the install around it and the accessories are what tie it together. This collection covers the parts that finish the job. Protective covers, flush and bracket mounts, NMEA 2000 and Garmin Marine Network cables, transducer adapters, power cables, and the small kits that come up mid project are all here. We stock the range so you can spec a clean rig the first time instead of waiting on a forgotten cable in the middle of an install.

Protect the display

A sun and spray cover is cheap insurance for an expensive screen. Garmin offers magnetic and plastic covers sized to specific display models so match the cover to your exact unit and screen size. On a boat that sits on a trailer or a mooring that cover is the difference between a clear screen and a chalky one in a couple of seasons.

Mount it solid

Flush mounts give a clean dash look while bracket and tilt mounts let you angle the screen and pull it for storage. Check the mount against your unit and the space behind the dash before you cut because a flush mount needs clearance for the connectors and the cable bend radius.

Get the networking right

Garmin units share data two ways. NMEA 2000 carries engine data, sensors, and autopilot info. The Garmin Marine Network is a faster link for radar, sonar black boxes, and chart sharing between displays. Buy the correct cable type and length for each and add the tees, terminators, and adapters a clean backbone needs. Mixing up the two networks is the most common install snag so confirm which port you are feeding before you order.

Power and adapters

Match the power cable to your unit and use transducer adapters when you are mating an existing transducer to a new head unit so you can reuse the in hull hardware. The right adapter saves pulling a transducer you already trust and know works. Not sure which accessory fits your model. Tell our techs your Garmin unit and what you are building and we will match the cover, mount, cables, and adapters so the whole system bolts up and talks to itself the first time you power it on. Always verify connector type and cable length against the installation manual for your specific model before ordering.
