Estimated Delivery by: --
Garmin Montana 710 Rugged GPS Handheld Navigator
The Garmin Montana 710 is a full-size, multi-activity handheld GPS navigator built for demanding outdoor conditions. At the center is a 5-inch glove-friendly touchscreen — the largest display in Garmin's handheld lineup — displaying TopoActive maps with terrain contours, elevations, trails, rivers, and routable road and trail data preloaded worldwide.
The unit carries 32 GB of onboard storage for additional map downloads, high-resolution satellite imagery, waypoints, tracks, and routes. Ruggedness is certified to MIL-STD-810 for thermal, shock, and vibration, and rated IPX7 for water-resistance up to one meter. Built-in ABC sensors provide barometric altimeter data for elevation tracking, a barometer for weather trend monitoring, and a 3-axis electronic compass for direction without relying on satellite lock. Multi-GNSS support covers GPS and Galileo for reliable acquisition in challenging environments including deep canyons, dense forest, and high latitudes. Battery life reaches 24 hours in GPS mode and up to 432 hours in expedition mode. Charging is via standard USB-C.
The Montana 710i adds built-in inReach satellite communication technology — two-way messaging and interactive SOS via the Iridium network — for use beyond cell coverage (active subscription required).
Our Take: The Montana 710 occupies a specific niche — it is the GPS handheld you choose when you need the largest possible screen and the ability to mount the device on a vehicle while also using it on foot. The 5-inch display is not matched by any other current Garmin handheld, and the glove-friendly touchscreen works in genuine field conditions including heavy rain and cold-weather gloves. For multi-activity use — hiking, ATV, motorcycle, boat, overlanding — the Montana's mounting ecosystem is the deepest in Garmin's lineup. The 32 GB of storage is practically unlimited for map data. The upgrade from the Montana 700 to the 710 is meaningful: the 710 introduces USB-C charging (replacing micro-USB), a higher-capacity 4350 mAh battery (up from 3100 mAh for an extra 6 hours of GPS runtime), and global TopoActive maps preloaded worldwide. If you are coming from a Montana 6xx or 7xx and need a replacement, the 710 is a worthwhile update. The 710i is the right choice if you operate in areas with no cell coverage where emergency communication capability is genuinely important.

-
Integrated Wi-Fi allows the Montana 710 to download maps, satellite imagery, software updates, and Outdoor Maps+ content directly without a computer. Connect to any available Wi-Fi network. Content can also be transferred from a computer using Garmin Express.
-
The Garmin Explore smartphone app (free, iOS and Android) pairs with the Montana 710 and 710i via Bluetooth for trip planning, route sync, waypoint management, and post-trip review. Active weather forecasts from the Garmin Connect app are also accessible when paired with a smartphone. LiveTrack lets other Garmin GPS users follow your tracks and routes in real time.
-
The Montana 710's mounting interface is compatible with a wide range of sold-separately Garmin vehicle mounts including motorcycle, ATV, bicycle, car, truck, and RV options. RAM mount adapter compatibility extends mounting options further. The Montana 710 is designed specifically as a vehicle-mountable handheld — a key differentiator from smaller Garmin handhelds.
Montana 710i — inReach satellite communication features
- Two-way satellite messaging via Iridium network — send and receive text messages to and from any mobile phone number or email address from anywhere on Earth, including areas with no cellular coverage. The 5-inch QWERTY on-screen keyboard makes composing messages faster on the 710i than on smaller inReach devices.

Frequently Asked Questions
What is the difference between the Montana 710 and the Montana 710i?
Both models share identical hardware: same 5-inch display, same 32 GB storage, same MIL-STD-810 and IPX7 ratings, same ABC sensors, and same GPS battery life. The Montana 710i adds built-in inReach satellite communication technology, enabling two-way text messaging and interactive SOS via the Iridium network when beyond cell coverage — features that require an active inReach satellite subscription. The 710i also includes City Navigator routable road maps for turn-by-turn driving directions, which the standard 710 does not include. The standard Montana 710 at $649.99 is the right choice if you operate within cell coverage areas and do not need satellite communication. The 710i at $799.99 is designed for users who regularly go beyond cell range.
Does the Montana 710i require a subscription?
The inReach satellite features — two-way messaging, interactive SOS, and inReach weather — require an active Garmin inReach satellite subscription, purchased separately from Garmin. The Montana 710i functions as a fully capable GPS navigator without any subscription: all mapping, navigation, ABC sensors, Wi-Fi, Bluetooth, track recording, and satellite imagery features work without a subscription. Only the Iridium satellite communication features are subscription-gated.
What maps come preloaded on the Montana 710?
The Montana 710 comes preloaded with TopoActive worldwide topographic maps — routable terrain maps covering the entire world with contours, elevations, trails, roads, rivers, coastlines, and points of interest. The Montana 710i additionally includes City Navigator maps for routable turn-by-turn driving directions. Both models support downloading additional maps — including BlueChart g3 nautical charts and Outdoor Maps+ subscription content — over Wi-Fi directly to the 32 GB onboard storage without a computer.
How long does the Montana 710 battery last?
In standard GPS mode, the lithium-ion battery provides up to 24 hours of runtime — a significant improvement over the Montana 700 series (18 hours), thanks to the 4350 mAh battery replacing the 3100 mAh unit. In expedition mode, the device reduces GPS recording frequency and turns off the display between updates, extending battery life to up to 432 hours for the 710 (approximately 18 days) — useful for multi-week expeditions. An optional AA battery pack (sold separately) allows field replacement using three standard AA batteries without requiring a charger or electrical outlet.
What does MIL-STD-810 mean, and what is IPX7?
MIL-STD-810 is a US Department of Defense standard that specifies test methods for environmental and mechanical durability. The Montana 710 is tested to MIL-STD-810 for three specific categories: thermal (operation across extreme temperature ranges), shock (drop and impact resistance), and vibration (sustained vibration from vehicle mounting). IPX7 is an IEC water ingress protection rating certifying that the device can be submerged in 1 meter of water for up to 30 minutes without water damage — suitable for rain, splashing, and accidental water drops. Together these ratings make the Montana 710 genuinely field-ready for demanding outdoor conditions.
Can the Montana 710 be mounted on a motorcycle, ATV, or bicycle?
Yes. The Montana 710 is specifically designed as a vehicle-mountable handheld, with a mounting interface compatible with Garmin's wide range of vehicle mounts — all sold separately. Options include motorcycle handlebar and mirror mounts, ATV handlebar and roll bar mounts, bicycle mounts, dashboard mounts, and RAM mount adapters. When mounted on a vehicle, the device can be powered continuously via USB-C from a standard vehicle 12V USB-C adapter, eliminating battery concerns during long rides.
What is the difference between the Montana 710, 710i, and 760i?
All three models share the same hardware platform: same 5-inch display, same 32 GB storage, same MIL-STD-810 and IPX7 ratings, same sensors, and same GPS hardware. The Montana 710 is GPS navigation only, with no inReach capability. The Montana 710i adds built-in inReach satellite communication (two-way messaging, SOS) and City Navigator road maps. The Montana 760i has everything the 710i has plus a built-in 8 MP camera with GPS geotagging — photos are automatically stamped with their precise GPS coordinates for overlay on maps.
Does the Montana 710 have Wi-Fi?
Yes. The Montana 710 and 710i both have built-in Wi-Fi for downloading maps, satellite imagery, software updates, and Outdoor Maps+ subscription content directly to the device without a computer. The device connects to any available Wi-Fi network, and downloads run in the background. This makes the Montana 710 one of the most convenient Garmin handhelds for keeping maps and imagery current in the field or at home.
