Garmin inReach Mini 3 SOS Satellite Communicator

PMB Performance · Authorized Garmin Retailer

The trail does not end where the cell signal does. Garmin inReach Mini 3 adds a compact satellite text and SOS communicator to the equipment you take beyond coverage. It works on its own touchscreen and pairs with selected Garmin vehicle navigators, including Tread 2, making it a useful addition to the rig and a portable communication option when you leave the vehicle.

Communication beyond the cell network

With an active satellite subscription, send and receive text messages over the global Iridium satellite network. Type directly on the touchscreen keyboard, or use Garmin Messenger on a compatible paired smartphone for contacts, emojis, reactions and group conversations.

Interactive SOS sends your GPS coordinates and allows communication with Garmin Response, Garmin’s internationally staffed 24/7 emergency coordination center. Location sharing through LiveTrack lets chosen people follow your progress, including trip distance, time and elevation.

Simple check-in messages do not count toward the plan’s allotted text messages as described by Garmin. Custom texts, tracking and other satellite uses remain subject to the active plan and its current terms.

Garmin Messenger uses available Wi-Fi or the paired phone’s cellular connection and switches to satellite service when those connections are unavailable. Satellite communication still requires an active plan; the purchase price is for the hardware.

A useful partner for your Tread 2

Garmin’s compatibility listings explicitly include Tread 2, Tread 2 Overland, Tread 2 SxS and zūmo XT3. Supported inReach remote functions let compatible Garmin equipment access messaging and SOS capabilities while the communicator provides the satellite connection.

Compatibility is specific to the device and function. Do not assume that every Tread-branded navigator supports the same pairing. A paired navigator and its map display are separate purchases.

Use Garmin Explore on a compatible smartphone to plan a course and follow it out and back. The communicator supports point-to-point navigation and TracBack for returning along a recorded path. A digital compass provides bearings even when stopped.

Garmin Share transfers saved locations and courses between compatible devices. Multi-band GNSS support includes GPS, Galileo, QZSS and BeiDou. Weather reports and destination forecasts support trip planning; the full specification table identifies functions supplied through Garmin Explore.

Built to leave the vehicle with you

The unit weighs 4.31 ounces (122.2 g) and measures 2.16 × 3.85 × 1.05 inches. The sunlight-readable 1.9-inch color MIP touchscreen runs at 306 × 230 resolution under chemically strengthened glass. IP67 protection and Garmin’s stated MIL-STD-810 thermal, shock and water testing apply to the bare unit.

An internal rechargeable lithium-ion battery and USB-C interface support a compact travel setup. Garmin rates the Mini 3 for up to 350 hours with a 10-minute tracking send interval. That is a specific operating mode, not the runtime of every configuration.

The current Mini 3 manual lists up to 170 hours with 10-minute tracking plus high-detail GPS activity recording, up to 120 hours with high-detail recording using all satellite systems, and up to 105 hours at a 2-minute tracking interval. Settings, recording detail and sky view affect actual runtime.

Plan the connection before the remote miles

The communicator needs a clear view of the sky to send messages and tracking points; Garmin recommends orienting its antenna toward the sky for the best connection. For vehicle travel, choose a position that provides that view rather than assuming a closed storage compartment will communicate reliably.

Activate the satellite subscription and perform Garmin’s outdoor Test Device procedure before a trip. Wait for the test confirmation so you know the service is active. Satellite delivery depends on acquiring a usable signal and should not be treated as instantaneous.

The box contains the Mini 3, charging/data cable and documentation. A navigator, phone, vehicle mounting accessories, satellite service and compatible charging power source are separate from this hardware package.

Before installation and use

• An active satellite subscription is required for satellite messaging, SOS and tracking. Plan fees, allowances and conditions are set by Garmin and are additional to the device price.
• Some jurisdictions regulate or prohibit satellite communicators. Know and follow the rules where you intend to use the device.
• Maintain a clear sky view, test service before departure and plan charging for your chosen settings. Global network coverage does not guarantee immediate communication from every installation or terrain position.
• App-connected features require compatible devices and the applicable Bluetooth, Wi-Fi or cellular connection. This listing is the Mini 3 text/SOS communicator, SKU 010-03387-00.
