Garmin OnDeck GTB 10 Boat Monitoring System, Security Sensor Included, Temperature Sensor Included, Shore Power Sensor Included, Controls Up to 5 Switches, 3G/4G Cellular, NMEA 2000, 10-32V, IPX7, 48-Hour Battery Backup

Overview

The Garmin 010-02134-00 is an OnDeck Hub that lets you track, monitor, and control key boat systems from the ActiveCaptain app using Wi-Fi and 3G/4G cellular connectivity. It runs on 10 to 32 Vdc and has an internal backup battery that can keep the hub accessible for up to 48 hours if boat power is disconnected.

It can send text alerts for events like a triggered security sensor, shore power loss, bilge activity, battery voltage changes, and temperature alarms. GPS tracking supports geofence alerts, with location updates every 15 or 30 minutes depending on power status, and vessel data can be stored in the cloud for up to 30 days.

On boats with Garmin electronics, it can tie into the Garmin Marine Network and an NMEA 2000 backbone to bring additional data into one place, then add wired sensors and relay switching where you need it.

Key features

• Input voltage range: 10 to 32 Vdc (covers common 12 V and 24 V systems)
• Cellular connectivity (3G/4G) plus onboard Wi-Fi for setup and local access
• Internal backup battery supports access for up to 48 hours after a power disconnect
• Remote control of up to five relay switches from the hub and the app
• Monitoring support for 2 bilge pumps, 2 battery voltage inputs, shore power, temperature, and up to 30 security sensors
• GPS tracking with geofence and offline alarms; monitoring interval listed as 15 minutes
• Physical size without antennas: 9.1 x 1.9 x 5.6 in (23.1 x 4.9 x 14.2 cm); weight: 1.4 lb (0.64 kg)
• Power consumption up to 20 W at 10 Vdc

Installation and setup

Mount the hub where it stays above the waterline and has ventilation, with connectors facing up on a horizontal surface or out on a vertical surface. Antennas need to be oriented toward the sky for reception; if the hub is installed inside a cabin, placing it near a window helps with cellular signal.

The power lead uses an in-line 7.5 A fast-acting fuse (rated 42 V). For continuous monitoring when the ignition is off, power is typically taken directly from the boat battery rather than through an ignition feed.

Connectivity and system integration

Connect the hub to a compatible Garmin chartplotter over the Garmin Marine Network and to your NMEA 2000 backbone to pull in compatible data such as depth, wind, fluid level, and engine information. Switch control can also be expanded using NMEA 2000 momentary or latching switch support through supported digital switching interfaces.

Remote access requires an active subscription and cellular coverage at the boat. Your phone or tablet also needs its own connection to reach the system when you are away.

Use cases on board

This setup fits boats that sit unattended at a dock, on a mooring, or in storage, where shore power drops, bilge pump activity, or an open entry point are the main concerns. It also works well when you want simple remote control over a few onboard circuits like a charger, refrigerator, or cabin lights while keeping tabs on location.

Maintenance and care

Keep unused connectors capped and check sensor wiring for corrosion if it lives in a damp locker. Staying current with app and device updates helps keep alerts, switching, and connectivity behaving consistently over time.

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.

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.
