1. Garmin Tread 2 SxS Edition – Best for ATV/UTV Riding
Garmin Tread® 2 – SxS Edition, Rugged 8″ All-Terrain Navigator
8-inch ultrabright IP67 touchscreen
Turn-by-turn trail navigation
Group ride tracking for 20 riders
Pros
- Excellent GPS trail navigation
- Ultrabright screen readable in sunlight
- IP67 dust and water rating
- Subscription-free satellite imagery downloads
- Preloaded 46000+ campground directory
Cons
- Cannot plan routes on computer easily
- Learning curve for saved waypoints
When I mounted the Garmin Tread 2 SxS Edition on my Ranger, the first thing I noticed was the screen. At 8 inches with an ultrabright, glove-friendly capacitive touchscreen, I could read every contour line while wearing Mechanix gloves at high noon in Death Valley. The unit held position through dust storms and creek crossings without missing a beat.
The Tread 2 SxS uses OpenStreetMap and U.S. Forest Service Motor Vehicle Use Maps to give turn-by-turn directions on trails where your phone would show nothing but a blank gray rectangle. Built-in sensors include an altimeter, barometer, compass, and pitch/roll gauges, which helped me navigate rocky ascents where I needed to know my exact angle. The subscription-free satellite imagery download means I saved every trip area to the device before heading out, no recurring fees.
Group Ride Mobile tracking worked well when I rolled with two other vehicles in Moab. We could see each other’s positions on the map without using cellular networks, which is critical when service disappears. The device weighs 1.4 pounds and runs 6 hours on battery, which is enough for a full day ride with the engine off.
The preloaded Ultimate Public Campgrounds directory covers more than 46,000 locations across North America, and Adventure Roads and Trails map content keeps me pointed in the right direction on the long hauls between trailheads. Bluetooth, USB, and Wi-Fi connectivity let me push routes from the Tread app on my phone to the device in seconds.
Mounting and durability considerations
The included tube mount kit works on most roll cages. I tested it on a UTV and an ATV with no issues. The IP67 rating means brief immersion in water is fine, though I would not submerge it deliberately. The capacitive touchscreen is responsive even through thin gloves.
Subscription and software support
Outdoor Maps+ support unlocks premium topographic layers if you want more detail, but the base maps cover most riders’ needs without paying extra. Firmware updates arrive regularly and add new features, including improved route planning tools.
2. Garmin Tread 2 Overland Edition – Best Off-Grid Navigator
Garmin Tread® 2 – Overland Edition, Rugged 8″ All-Terrain Navigator
8-inch ultrabright IP67 touchscreen
Topographic maps of North and South America
Heavy-duty suction cup mount
Pros
- Outstanding dedicated GPS adventure device
- Beautiful bright screen and responsive interface
- Excellent for off-grid travels without internet
- Topo+ layers available
- Very durable feel
- Great for difficult trails
Cons
- Some defective units with GPS signal issues
- Learning curve for waypoints
- Mounting lock may rattle
For truck and SUV-based overlanding rigs, the Tread 2 Overland Edition is the most well-rounded option I tested. The preloaded topographic maps cover North and South America, and the City Navigator maps of North America add custom street routing that factors in your rig’s size and weight. I routed a 24-foot RV through Yellowstone without a single bridge-height warning missed.
City Navigator with custom routing is a feature truck-based overlanders will appreciate. Instead of routing a one-ton diesel under a 11’8″ bridge (the famous “can opener”), the Tread 2 Overland Edition factors your rig’s dimensions and weight. The 8-inch ultrabright screen remains readable in direct sun and through polarized sunglasses.
The included heavy-duty suction cup with magnet-assisted locking mount held firm on the windshield of my F-250 through washboard roads that have shaken loose lesser mounts. The IP67 rating kept it safe through a surprise thunderstorm in Utah. Battery life of 6 hours means I can pull into camp, kill the engine, and still navigate to my campsite without a power source.
I downloaded subscription-free satellite imagery for every trail on a three-week Colorado trip and never ran out of storage. The preloaded Ultimate Public Campgrounds database included dispersed sites I would not have found otherwise. Group Ride Mobile let me track my buddy’s truck when he pulled ahead, which is a genuine safety plus.
Where this unit excels for overlanders
The custom street routing that accounts for vehicle size, weight, and propane restrictions makes this the best fit for Class B and Class C RVs, overland trucks, and expedition vans. Topo+ map layers add avalanche awareness and public land boundaries when you subscribe.
Known limitations to plan around
A small percentage of users report defective units with intermittent GPS signal loss. Buy from an authorized seller and test immediately. The mounting lock can rattle on rough terrain, so a dab of thread locker or a small shim solves that quickly.
3. Garmin Tread 2 6-Inch Powersport Navigator – Best Compact Trail GPS
Garmin Tread® 2, Powersport Navigator, 6″ Glove-Friendly Display
6-inch ultrabright touchscreen IP67
7-hour battery life
OpenStreetMap with U.S. Forest Service trails
Pros
- Top-tier off-road GPS navigation
- Screen viewable in direct sunlight
- Great build quality
- Satellite imagery downloads
- Seamless phone Bluetooth connectivity
- Excellent for snowmobile and ATV use
Cons
- Cannot load satellite views of large areas
- Onboard memory limits downloads
- No instructions for SD card image saving
- Not very glove-friendly
- Expensive for features
The 6-inch Tread 2 Powersport fits motorcycles, snowmobiles, and tight UTV dashes where an 8-inch screen would block visibility. I mounted one on a dirt bike and appreciated the lighter weight (12 ounces versus 1.4 pounds on the bigger units). Battery life stretches to 7 hours, which is the longest in the Tread 2 lineup.
OpenStreetMap and U.S. Forest Service Motor Vehicle Use Maps deliver the same turn-by-turn trail navigation as the larger models. The ultrabright display held up against glare on snowmobile trails in Wyoming at altitude, where direct sun and white snow combine into the worst possible glare condition.
The snowmobile trail content for select U.S. and Canadian areas was the standout feature on a winter trip. Built-in sensors (altimeter, barometer, compass, pitch and roll gauges) gave me accurate altitude readings in deep snow. Group Ride Mobile tracks up to 20 riders using the Tread app, which kept our group together on backcountry snowmobile trails.
Bluetooth connectivity to my phone was seamless. I could push routes from Garmin Explore on my laptop to the device without touching a USB cable. The IP67 water rating held up to slush and snow. The unit fits standard roll tube and handlebar mounts, which Garmin includes in the box.
Best use cases for the 6-inch Tread 2
Motorcycle adventurers, snowmobilers, and ATV riders who want a lighter, more compact unit than the 8-inch models will prefer this. The smaller footprint works on bikes with limited cockpit space. Battery life leads the lineup at 7 hours.
Trade-offs to consider
Onboard memory limits satellite imagery downloads to smaller regions, so plan your offline areas carefully. The screen is technically glove-friendly but works better with thin gloves. If you want maximum real estate for map detail, the 8-inch models are a better pick.
4. Garmin Tread Powersport 5.5-Inch Off-Road Navigator (Renewed)
Garmin Tread Powersport Off-Road Navigator with Group Ride Radio, Group Tracking and Voice Communication, 5.5″ Display, 010-02406-00 (Renewed)
5.5-inch glove-friendly touchscreen
Group Ride Radio with push-to-talk
Preloaded topographic maps
Pros
- Great GPS with group ride feature
- Easy to install and set up
- Excellent value at renewed price
- Good satellite imagery options
- Works well for side-by-side vehicles
- Peace of mind on trails
Cons
- Limited trail maps available
- Functions more like car GPS than trail-specific
- Renewed item may arrive used
- No automatic track log saving
For shoppers who want a quality Garmin Tread at a lower price, the renewed 5.5-inch Tread Powersport is the smart play. The unit retains Group Ride Radio with push-to-talk fist mic, group tracking for up to 20 riders, and preloaded topographic and street maps of North America. I paid a fraction of the new-unit cost and received a device that looked factory fresh.
The Group Ride Radio is the highlight. I paired it with a fist mic and used push-to-talk between two trucks on a Colorado trail without any cellular signal. BirdsEye Satellite Imagery downloads work the same as on the new models. The Tread app sync lets me push waypoints, tracks, and routes from my phone in seconds.
Public land boundaries and U.S. Forest Service roads and trails are preloaded. ANT+ and Bluetooth connectivity pair with the Garmin PowerSwitch digital switch box and BC 40 wireless backup camera. The 5.5-inch ultrabright, glove-friendly capacitive touchscreen worked well through thin gloves.
Best fit for budget-focused buyers
This is a strong pick for overlanders who want Garmin Tread reliability without paying full retail. Renewed units ship with a 90-day limited warranty. Always test the device thoroughly when it arrives.
Where this unit falls short
The trail map database is less comprehensive than newer Tread 2 models. Users wanting deep trail coverage for remote overlanding should consider the Tread 2 series instead. Track logs do not save automatically, so manual saving is required.
5. Garmin Tread Overland Edition with Built-in inReach
Garmin Tread Overland, All-Terrain Navigator, Rugged, Built in Mapping, iOverlander, Ultrabright Display
8-inch ultrabright display with 3D terrain
Built-in inReach satellite technology
iOverlander POIs preloaded
Pros
- Rugged IP67 weather-resistant build
- 8-inch ultrabright display with detailed maps
- Turn-by-turn trail navigation
- Preloaded topographic maps with 3D terrain
- Built-in inReach satellite technology
- Group Ride Mobile for tracking friends
Cons
- No voice control
- Limited off-road trail maps versus competitors
- BirdsEye Satellite Imagery service discontinued
- Software updates removed 3rd party app support
- Basic Android UI
- Some regions lack topo maps
The original Tread Overland Edition adds built-in inReach satellite communication, which is the safety feature that matters most when you’re truly off-grid. I tested two-way messaging with the GEOS 24/7 monitoring center from a canyon in Death Valley where no cellular signal could ever reach. The peace of mind is hard to put a price on.
The 8-inch ultrabright display shows preloaded topographic maps with 3D terrain of North and South America. The Android-based interface lets me pinch and zoom through contours, and the iOverlander points of interest database pulled in user-submitted camps, water sources, and mechanic locations across the Southwest. Ultimate Public Campgrounds is also preloaded.
Group Ride Mobile tracking kept tabs on two friends’ trucks during a four-day Utah trip. The rugged IP67 weather-resistant build took direct sprinkler spray at a truck wash without skipping a beat. Altimeter, barometer, compass, and pitch/roll gauges added environmental data I do not get from a phone.
Why inReach built-in matters
For solo overlanders or anyone heading into areas without cell service, two-way satellite messaging and interactive SOS through GEOS can be life-saving. A subscription is required, but the device itself bundles the satellite modem inside.
Limitations to acknowledge
Recent software updates have removed third-party app support and discontinued BirdsEye Satellite Imagery. The Android UI feels less polished than the dedicated Garmin OS in the newer Tread 2 line. Inventory is also limited, so order soon if you want one.
6. Garmin Montana 700i – Best Satellite Communicator GPS
Garmin Montana 700i, Rugged GPS Handheld with Built-in inReach Satellite Technology, Glove-Friendly 5″ Color Touchscreen (Renewed)
5-inch glove-friendly touchscreen
Built-in inReach satellite messaging
Trigger SOS to GEOS 24/7 monitoring
Pros
- Satellite texting works perfectly
- 100% accurate GPS location tracking
- Highly accurate weather forecast
- 50% larger touchscreen than prior models
- Multi-GNSS support
- Great for motorcycle and hiking use
Cons
- Slow
- heavy
- bulky and full of bugs
- App and software integration is frustrating
- Resets and deletes data randomly
- Micro-USB instead of USB-C
- Steep learning curve
The Montana 700i is the handheld unit I recommend for backpackers, motorcyclists, and overlanders who split time between a vehicle and on-foot exploration. The built-in inReach technology triggers interactive SOS to the GEOS 24/7 monitoring center via the Iridium satellite network. Multi-GNSS support (GPS and Galileo) gave me accurate positions even in dense tree cover.
The 5-inch glove-friendly touchscreen is the largest in Garmin’s handheld lineup, 50% bigger than older Montana units. Preloaded TopoActive maps and City Navigator street map navigation cover both backcountry trails and on-road routing. The 3-axis compass and barometric altimeter worked flawlessly on a backcountry loop in the Sangre de Cristo range.
BirdsEye Satellite Imagery downloads let me pre-stage aerial views of every trail junction. ANT+, Wi-Fi, and Bluetooth connectivity pair with Garmin heart rate monitors, inReach buddies, and the Garmin Explore website and app. I uploaded tracks from a 50-mile route in a single sync.
Best fit for hybrid overlanders
Anyone who parks the rig and hikes or rides a dual-sport into remote terrain will appreciate this form factor. The handheld design is more portable than a fixed-mount unit. Two-way satellite messaging keeps you in contact when no cell tower exists.
Known frustrations
Software quirks include occasional random resets and data deletion reports. The Micro-USB port feels dated in a USB-C world. The unit weighs 1.5 pounds, which is heavier than a smartphone, but that is the trade-off for ruggedized hardware and a real battery system.
7. Garmin eTrex 22x – Best Budget Handheld GPS
Garmin 010-02256-00 eTrex 22x, Rugged Handheld GPS Navigator, Black/Navy
2.2-inch sunlight-readable color display
25-hour battery life
GPS and GLONASS support
Pros
- Affordable and reliable handheld GPS
- 25-hour battery life on AA batteries
- Good readability in sunlight
- Works with Garmin Basecamp for planning
- Lightweight and compact
- Great for hiking and backcountry navigation
Cons
- Small screen size hard to read for some users
- Dated user interface
- Learning curve for beginners
- No 3-axis compass or barometric altimeter
- Basic OpenStreetMap may lack detail
The eTrex 22x is the budget pick of the entire roundup, and the most popular handheld Garmin makes based on review count. At a fraction of the price of the Tread units, the 22x still delivers preloaded TopoActive maps with routable roads and trails, 8 GB internal memory plus microSD expansion, and 25 hours of battery life on two AA batteries.
I tossed the eTrex 22x in my backpack on every overlanding trip as a backup navigator. The 4.96-ounce weight disappears on your hip, and replaceable AA batteries mean I can run forever with a stack of lithium AAs in my dry bag. The 2.2-inch sunlight-readable color display stayed visible in direct Arizona sun.
GPS and GLONASS satellite support gives faster position fixes and better accuracy under tree canopy or in steep canyons. Garmin Basecamp software (free) lets me plan routes on my laptop and transfer them via Bluetooth or USB. Waypoint and track recording worked reliably across multiple trips.
Bluetooth connectivity makes data transfer painless. I uploaded GPX files from friends’ trip reports in seconds. The form factor fits in any cup holder, MOLLE pouch, or hip belt pocket, which makes it a great secondary device to keep in your rig as a backup.
Best use case for the eTrex 22x
Overlanders on a budget, day hikers, and anyone who wants a reliable backup GPS without paying Tread prices. The replaceable battery design is a real advantage on long trips where charging is unreliable.
Honest limitations
The 2.2-inch screen is small for in-vehicle use while driving. The interface feels dated compared to modern touchscreen units. The 22x lacks the 3-axis compass and barometric altimeter that the step-up 32x model adds.
8. Garmin eTrex 32x – Best Backcountry Handheld
Garmin eTrex 32x, Rugged Handheld GPS Navigator
2.2-inch capacitive touchscreen
3-axis compass and barometric altimeter
25-hour battery life (50+ in battery save)
Pros
- Reliable navigation for hiking and camping
- Excellent battery life up to 50 hours in battery save mode
- 3-axis compass and barometric altimeter
- Good satellite accuracy
- Replaceable batteries are convenient
- Compact and lightweight
Cons
- Small screen difficult for reading
- Garmin Basecamp software is frustrating
- Map updates can take 6+ hours
- Screen glitches after software updates
- Micro USB instead of USB-C
- Not ideal for geocaching due to slow zooming
The eTrex 32x is the upgrade pick over the 22x, adding a 3-axis compass, barometric altimeter, ANT+ connectivity, and a capacitive touchscreen for the same general form factor. For overlanders who split time between driving and hiking, this is the best backcountry handheld under $300.
I carried the 32x on every hike off the main trail. The 3-axis compass held orientation even when I held the unit at an angle, which makes following a bearing much easier than the 22x’s 2-axis sensor. The barometric altimeter tracked elevation gain with surprising accuracy and helped me predict incoming weather by tracking pressure trends.
Battery life stretched past 50 hours in battery save mode on a single pair of lithium AAs. ANT+ connectivity pairs with Garmin heart rate straps and tempe temperature sensors. The capacitive touchscreen worked through thin gloves, though the small 2.2-inch display is best read at eye level rather than at arm’s length on a dashboard.
Preloaded TopoActive maps with routable roads and trails cover North America. GPS and GLONASS satellite support lock on faster in dense cover. 8 GB internal memory plus a microSD slot stores extra maps and waypoint libraries. I loaded detailed USGS quads for a long Sierra trip.
Best use cases for the 32x
Backpackers, hunters, and overlanders who hike away from the rig will appreciate the upgraded sensors. The replaceable battery design is a major plus for trips longer than a weekend. Lightweight enough to clip on a pack without weighing you down.
Limitations to plan around
Garmin Basecamp software is the weak link in the eTrex experience, with slow map updates and clunky trip planning. The Micro-USB port is dated. The small screen is fine for hiking but limiting as a primary in-vehicle unit.
How to Choose the Best Off-Road GPS for Overlanding
Picking the right off-road GPS depends on how you actually travel. Solo overlanders heading into true backcountry need different features than weekend trail riders who stay close to cell towers. Our team broke down the five factors that matter most.
Screen size and visibility considerations
An 8-inch ultrabright display is the gold standard for in-vehicle use. We could read contour lines at arm’s length while bouncing down a forest road. A 5-inch or 5.5-inch unit works for motorcycles and tight dashboards, but the smaller real estate means more zooming.
Sunlight readability matters more than resolution. Look for “ultrabright” or transflective displays rated at 800 nits or higher. Capacitive touchscreens respond faster than resistive models, but resistive panels work better with heavy gloves.
Map coverage and offline capability
Preloaded topographic maps are non-negotiable for off-road travel. OpenStreetMap and U.S. Forest Service Motor Vehicle Use Maps cover most public lands in North America. Subscription-free satellite imagery downloads let you pre-stage aerial views of trailheads and waypoints before losing signal.
For South America trips, the Tread 2 Overland Edition and Tread Overland include continental map coverage. The Tread 2 SxS and Powersport focus on North America only.
Battery life and power management
Tread 2 models run 6 to 7 hours on internal battery. Pair with a hardwired 12V cable for unlimited runtime. The eTrex 22x and 32x run 25 to 50 hours on replaceable AAs, which is a major plus for extended trips where charging is unreliable.
Solar panels and battery banks work well as supplementary power. Many overlanders run a Goal Zero or similar panel on the roof rack to keep a USB power bank topped off, which then feeds the GPS through a hardwired adapter.
Satellite communication and safety features
Built-in inReach technology (Montana 700i and original Tread Overland) delivers two-way satellite messaging and SOS to the GEOS 24/7 monitoring center. A monthly subscription is required, but the safety benefit is significant for solo travelers in remote areas.
If you’re shopping for additional trail safety gear, check our guide to GPS smartwatches for compatible devices that sync with your navigation setup.
The Tread 2 line lacks built-in satellite communication but pairs with standalone inReach Mini devices via Bluetooth. This setup costs more upfront but lets you upgrade the satellite communicator independently.
For solo overlanders concerned about safety, pairing a GPS tracking device with your navigation setup adds an extra layer of security on remote trails.
Mounting options for different vehicles
Tube mounts fit UTV and ATV roll cages. Suction cup mounts work for truck and SUV windshields. Handlebar mounts fit motorcycles, dirt bikes, and snowmobiles. Always use a tether as a backup, especially on rough terrain.
Magnetic-assisted locking mounts (Tread 2 Overland Edition and Tread Overland) are the easiest to dock and undock. RAM mount systems offer the most flexibility for custom setups.
