Garmin GPS 24xd NMEA 2000 GPS Sensor, Remanufactured, Magnetic Heading Sensor, Multi-Band GNSS, 10 Hz, IPX7

Overview

The Garmin 010-N2316-10 is a remanufactured GPS 24xd NMEA 2000 position sensor with an integrated magnetic heading sensor for boats that need steady GPS and heading data on the network. It updates position at 10 Hz and tracks GPS, Galileo, GLONASS, and BeiDou satellites, with typical marine accuracy under 50 cm (CEP 50%) and under 1.0 m (88%).

Because it outputs magnetic heading, chart orientation and radar overlay stay stable when the boat is moving slowly, docking, or trolling, where course over ground can lag or wander.

The case uses a high-impact plastic alloy with full gaskets and an IPX7 water rating for rain, spray, and washdowns. Power comes from the NMEA 2000 network (LEN 3) with typical draw of 150 mA at 12 V, and the included 6 m drop cable helps reach a nearby backbone run without splicing.

Key features

• NMEA 2000 position and heading output for compatible displays, instruments, radar overlay, and autopilot systems
• Integrated magnetic heading sensor with heading accuracy within 3 degrees for stable overlays at low speeds
• 10 Hz position updates for responsive on-screen movement and navigation data
• Expanded GNSS reception across GPS, Galileo, GLONASS, and BeiDou to hold lock in challenging coverage areas
• IPX7 water rating with a fully gasketed housing built for wet decks and routine washdowns
• 6 m (19 ft 8 in) NMEA 2000 drop cable included, plus NMEA 2000 load equivalency number (LEN) 3
• Mounting hardware supports surface, pole, and under-deck installation options (under-deck is for fiberglass surfaces only)
• Compass-safe distance of 150 mm (5.9 in) to help plan placement around compasses and other sensitive gear

Installation and setup

Mount it where it has a clear view of the sky and stays out of shadow from hardtops, masts, and radomes. Keep it away from speakers, strong magnets, and other sources of electrical noise, and do a quick handheld-compass check at the mounting spot to catch magnetic interference before you drill.

For pole mounting, it threads to a standard 1 in OD, 14 threads-per-inch pipe-threaded pole. Under-deck mounting only works under fiberglass; it will not acquire satellites through metal.

On the network side, connect it to a powered, properly terminated NMEA 2000 backbone using the included T-connector and drop cable. After installation, run heading calibration and auto heading alignment so connected electronics can use the magnetic heading output; alignment is done on calm, open water and requires the boat to reach at least 4 mph (6.4 km/h).

Maintenance and care

Rinse salt residue as needed and wipe the housing with a cloth dampened with mild detergent solution. Avoid chemical cleaners or solvents that can damage plastic components.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
