Garmin Tread Overland Edition GPS Navigator Detailed Review & Overview

Detailed Review & Overview for the All-New Garmin Tread Series Overland Edition: Trail Navigation, Route Planning, Emergency Communications & More

Wow, before we begin… this is one of the most dialed, heavy-duty, all-In-one off-road GPS units we have ever seen!

If you’re familiar with the popular Garmin Overlander navigation unit that came out a couple of years back, you’ll love the latest update to their off-road-focused lineup!

Building upon its popular features, the brand-new Garmin Tread Overland and SxS models offer a more comprehensive package for your outdoor adventures. I’m super stoked to share my thoughts and review the 8″ Tread Overland model, so keep reading to find out!

Garmin Tread Overland (available in 8″ and 10″ screen sizes)

Garmin – Long-Standing, Established Navigation Company

Garmin has a significant reputation in the outdoor recreation space. Despite branching out across various product markets in recent years, they have always had one theme: exploration.

One of my earliest memories of a Garmin product was my dad’s early car navigation device. This was long before the days of running GPS off your phone and well before cars had built-in navigation. Garmin started to bridge the gap between reading paper maps, printing out trip routes, and how we navigate our travels today.

As smartphones came onto the scene, dedicated GPS navigation units started to be rendered obsolete (to a degree). In light of this, Garmin began to expand its consumer base and make waves in the fitness and outdoor enthusiast market. I personally own a fitness watch in their Forerunner line (intended for runners) and their Fenix line is wildly popular for the serious explorer. The latter can be found with features such as trail breadcrumbing, GPS tracking, and emergency SOS.

Garmin Tread Series

Garmin Tread Navigator - Attached to Front Windshield with Suction Mount

So what would we get if we combined Garmin’s traditional car navigation unit with their more recent technology centered around the outdoors? We get the Garmin Tread series of navigation units. At a high level, these will navigate your adventure long after you’ve left the asphalt road. You now have trail navigation, emergency InReach, and location technology all wrapped into one device that is also IP67 weather resistant.

The new Tread series of navigation units come in two variants. The Tread Overland is available in 8″ or 10″ screen size, and Tread Powersport, is available with an 8″ screen. Fortunately, the internal hardware and software feature-set is identical in all models.

What is Garmin InReach?

InReach is a subscription-based, satellite communications service offered by Garmin. This technology brings the benefits of satellite communication in a more consumer-focused manner. Historically when we think of satellite communications, we think of a bulky satellite phone and maybe a large antenna.

Garmin currently offers a few easy-to-use handheld models that utilize this technology. The most significant benefit of bringing one of these devices with you off-grid is retaining the ability for emergency communications or even SOS notification to dedicated emergency response services.

What was until recently limited to a dedicated, handheld device is also built into the Garmin Tread Overland Series.

What’s in the Box?

The Tread Overland models will include the following:

  • Tread Overland Unit
  • Suction Cup Mount
  • Vehicle Power Cable
  • Locking magnet-assisted mount (to pair with the section cup)
  • USB-C Cable
  • Documentation

Build Quality

Solid Construction

Garmin Tread Overland Edition - Heavy-Duty, Solid Housing

Unsurprisingly, the build quality of the Tread Overland is top-notch.

This thing is definitely built for adventure, whether it’s mounted in your rig or carried on your person. There is zero play in the screen itself and the housing has zero flex. What I like most about the build quality is the rubberized texture all around. Although this device has a MIL-Spec drop rating, why put that to the test when you can help prevent dropping it altogether?

The weight of this device is significant, which isn’t necessarily a bad thing. It feels substantial and like it can take a beating. This is not built like a run-of-the-mill tablet, and I’m just glad that they beefed up the windshield mount to make sure it stays secure!

Capacitive Touch Screen

Garmin Tread Series Capacitive Touch Screen

The screen itself is super bright, and I’m not exaggerating at all here. I ran a system update out of the box, and upon restart, the screen brightness was defaulted to 100% and nearly blinded me. However, this brightness will come in handy when you’re hitting the trails in extra sunny weather.

A capacitive touch screen is used here, which means it has similar touch sensitivity to the phones or tablets that you’re used to. Older navigation units used to use resistive-type screens where you had to really press on them for input.

Magnetic Mount

Garmin Tread Series Overland Edition Magnetic Windshield Mount

I’m a massive fan of the magnetic windshield mount that the Tread Overland uses.

The unit charges wirelessly via metal contacts in the magnetic mount. This is a well-thought-out feature if you need to remove your device quickly. The magnet itself is plenty strong enough to hold the device in place while driving on pavement, but a sliding lock mechanism should always be used.

Software Features

Garmin Tread Series Software Features

Tread Overland devices operate on Android 10 and are fortunately reasonably snappy.

Garmin’s custom UI doesn’t seem to bog the device down too much and includes useful pitch/roll measurement apps.

Home Screen Customization

Customizing Garmin Home Screen on Overland Edition GPS

If you’re not a fan of how the default screen/widget configuration is out of the box, you have the freedom to rearrange it however you like.

Since this is based on Android, several other built-in widgets are available to add as you see fit. You can even add multiple home screens by just swiping right and adding to your heart’s content.

Pitch & Roll

Pitch & Roll on Garmin Tread Series Overland Edition

The Pitch and Roll app will display that exact information in real-time, which is fantastic if your rig doesn’t have a built-in option!

Altimeter, Barometer & Compass

Altimeter, Barometer & Compass - Garmin Tread Series Overland Edition

The “ABC” app helps you monitor your ascent/descent and a helpful compass all on one screen.

I like that these are all displayed in large, bold font to be super easy to read at a glance.

Weather Radar

Weather Radar on Garmin Tread Series Overland Edition

Check this app periodically to stay ahead of any inclement weather so you can plan accordingly.

This is especially useful if you have a complete camp set-up and bad news is on the way. Keep you and yours informed and safe out there!

Vehicle Profile

Garmin Tread Series Overland Edition - User Profile

Tread Overland takes into account several factors here. You can specify whether you drive an off-road capable vehicle, its size, if it has 4WD, and even how much ground clearance you have. Garmin helps take all of this into consideration so that you can pick and navigate trails that are appropriate for your vehicle.

You can even set your “Garmin Adventurous Routing” level, which determines how much pavement you want to stay on during your trip. There are four levels to choose from, and Garmin will let you know how each will affect your ETA (talk about attention to detail!).

If your current route encounters something that falls outside of the criteria you have set in the profile, you will see an advisory notice pop up during navigation. This is a feature that I would never have thought of but makes perfect sense. Knowing ahead of time whether you can make it through a trail should always be the first step in route planning.

Round Trip App

Garmin Tread Series Overland Edition - Round Trip Feature

One of the quirkiest features that I found was “Round Trip”.

This app was specifically designed for the most indecisive adventurer.

Garmin Adventurous Routing Feature

It will ask you for how far or long you want to drive, which direction, where you’re starting from and will output several round-trip routes that match your criteria.

If you’ve got a little one that only falls asleep on joy rides, this feature is definitely for you!

Discover Your Next Adventure

Detailed Review & Overview for Garmin Tread Series Navigator

Garmin Destination Discovery Feature

Garmin makes it easy to find or discover your next adventure in various ways. Use one of the built-in repositories to find your next destination or enter your own the old-school way; it’s totally up to you!

What I like most about having all of this built-in vs. pulling that from the cloud is that you can always pull them up. The downfall of web-based mapping is that route planning and research are nearly impossible when you’re out of cell range.

Route Planner & GPX File Import Ability

Route Planning & GPX File Importing for Garmin Tread Series

If you use popular trail map services, you can import the GPX files directly to your Tread Overland for use. This feature is killer! You can also do this in the Tread mobile app and wirelessly sync all of the data.

Once all of your waypoints have been loaded in, Tread Overland allows you to create full-blown travel routes. This will allow you to input all of your stops ahead of time rather than input a search at every stop along the way. Over time, you’ll likely accumulate tons of data, but Garmin has you covered with a MicroSD card expansion for storage.

Download Detailed Satellite Imagery

It’s never a bad idea to download sections of offline maps for the areas you plan on exploring.

The ability to download detailed satellite imagery is super helpful for route planning so you can spot significant obstacles.

Final Thoughts On Software

The software features are admittedly way more comprehensive than I thought they would be.

I had expected to see some offline navigation and driving metrics as I have experienced with previous dedicated navigation devices. I covered some of the most stand-out features that came with regular use to me, but there are certainly even more at your disposal with this device.

The Tread App

Garmin Tread Mobile App for Overland GPS

The Tread mobile app allows you to do all of your route planning on your phone and sync it all to your Tread device when you’re done. One significant benefit of this feature is that you’ll be able to do all of the route research and pull GPX (map) files anywhere you go. This feature is especially great when someone tells you about a new trail, but you might not have your Tread device on you.

The Tread Overland will also sync weather updates and message notifications when paired to your phone and in use. This, however, is provided that you still have a cell signal.

Real World Use

Easy To Detach

Garmin Tread Overland Edition - Strong Magnetic Mount for GPS Unit

The windshield mount that Garmin uses is super sturdy. With it, your device is both secure and easily detachable at the same time. I can press the on-device buttons and screen with zero movements.

In addition, I’ve taken some extremely rutted-out forest roads at moderate speed, and again, it didn’t budge. That’s impressive, considering this is not a lightweight device. What I like about a magnet mount is that the unit can be easily detached. This is great if I need to show a buddy something about the current route or if I need to leave the car parked somewhere.

Different Sizes For Different Rigs

All New Off-Road & Overland GPS Navigation from Garmin

If you drive a vehicle with a mid-size or smaller windshield, I would recommend going with an 8″ screen model as this already takes up a decent amount of your outward visibility.

The 10″ screen option would be more ideally suited for full-size vehicles.

S.O.S. – Always Within Reach

New Garmin Tread Series Navigator with SOS Emergency Feature

On the left side of the device, an S.O.S. button is covered by a bright orange door.

If you ever need emergency services quickly, say, in a vehicle rollover incident, press and hold this button to send an alert and your exact location to the proper authorities.

Clear Navigation

Navigation is super straightforward, and you can even display a side app simultaneously.

There are tons of options here, ranging from standard trip metrics to real-time elevation or pitch and roll.

Clicking on a pinned side app will launch it fully, and you can simply hit the back button to resume navigation. You have the option to display all of the relevant trip information that you need, and none that you don’t.

Built-in U.S. Public & Private Land Maps

Exploring public lands is always fun, but you occasionally cross over to private lands without noticing “Posted” signs. Knowing you’re treading on non-private land is huge. Having private land maps built-in means that you don’t need to scramble to find a cell signal and check that you are not trespassing. It goes without saying that not all private landowners will be equally as kind to unwelcomed guests.

Optional Equipment Add-Ons

Garmin PowerSwitch

The versatility of the Tread series continues with Garmin’s optional accessories. Although I didn’t get the chance to test these personally, the concept is awesome! Popular accessory switches typically involve running wires through the firewall to the switch located inside the cabin. Garmin’s PowerSwitch offers a wireless solution where the accessories connect to a module in your engine bay. From there, they can then be controlled via the Tread unit. In my opinion, this is a killer solution if custom wiring isn’t your jam.

Find It Online:

Garmin Group Ride Radio

If you like to travel in packs, this accessory makes it super simple to communicate and share each other’s location on group adventures. The Group Ride Radio will pair directly with your tread unit to enable push-to-talk communications. This is perfect in the event that anyone gets separated from the herd.

Find It Online:

Garmin GPS Dog Tracker

My dog isn’t willing to run alongside my rig while hitting the trails, but this is an excellent accessory if yours does. The Tread unit is compatible with Garmin’s dog tracking collar that is commonly used for sporting/hunting dogs. Pairing these devices lets you see your dog’s location as a direct overlay on your navigation screen. Pretty slick!

    Tread Series Overland Edition VS. Overlander

    Garmin Tread Series Overland Edition vs. Garmin Overlander

    Left: Garmin Tread Overland | Right: Garmin Overlander

    The names of the new Tread Overland and its predecessor may seem confusing. However, these devices have some major differences in their feature set.

    What’s the Same

    • Both devices feature similar navigation abilities
    • They have the same durable build quality
    • Both utilize magnetic mounting and charging to your windshield

    What’s New & Improved

    • Garmin Tread Overland starts with a higher resolution 8″ screen size whereas the older Overlander model was only available with a lower resolution 7″ screen
    • The Tread Overland is compatible with the mobile Tread app that allows you to sync all of your route-planning work between your devices
    • Battery life has been improved and nearly doubled in the new model (6-hours vs. 3-hours)
    • Garmin InReach built-in on Tread Overland vs. a separate InReach device needed for pairing to Overlander
    • Tread Overland is compatible with the optional accessories mentioned above, whereas the older model is not

    Tread Overland VS. Mobile Off-Road Apps

    I have some experience using Gaia maps on my phone and my 2021 head unit via Android Auto.

    While Gaia has a very robust set of features, I will say that its UI has a bit of a learning curve. When I’m behind the wheel, I want a simple UI. This is so that I can keep my eyes as focused on the road (or dirt), as long as possible. If you do wish to import GPX map files like you can in Gaia, you can do so with Tread Overland as well!

    Final Thoughts

    Durable GPS Navigation Setup for Off-Road & Overland Travel


    Although the price may seem a bit steep at first, you have to consider what this device is bringing to the table. With it, you won’t need a separate emergency communication device, navigation device, or a trail map subscription. Plus, purchasing these separately, would add up rather quickly. You could argue that your phone could do some of this via various apps. However, it’s always good to have more than one plan. If your phone gets damaged or lost and you rely solely on it, that’s no good.


    I am genuinely blown away by the Tread Overland series of navigation devices. It contains way more features than I could have imagined by a long shot. Not only can it help get you to where you need to go, but it can also help you find where you might want to go. This is truly a one-stop-shop device with native off-road navigation, the ability to store offline maps (just in case), and built-in InReach communications.

    The Garmin Tread Overland Series of devices has a solid use case for those who frequent going off the pavement. It has a comprehensive feature set that is also very easy to use. These are two things that don’t always go hand-in-hand regarding technology. I would love to hear your thoughts on this device or perhaps those like it! Does it sit at the top of your equipment list?

    Thanks for sticking with this read all the way through the end, and I’ll see you on the next one!

    Great review. I’m looking at buying the tread basic version 5 inch screen. Was wondering if you know how portable it is. I would like to use in my sxs and take it with me walking in the woods. Any info would be great. Thanks

    1 year ago

    While the Tread is for me truly great I miss a very simple feature that was in the overlander: automatic screen brightness. You have to bee fidling with brightness from time to time, especially at dusk. Another thing that should be improved is the rattling of the device locker when the device is not locked to the magnetic mount. Small nuances, but nuances.

    Maybe you should mention the dropping of Voice Recognition when moving to this unit from the Overlander.

    What is the source of Garmins maps. Are they really detailed. You said you have used Gaia maps. Will the Tread work with OnX maps. Does it include old trails and cat tails from the old Topo maps?

    There’s supposed to be a feature that will tell you the cost of fuel at stations near you. Did you test this? How does it get the fuel cost – is it tied into Gas Buddy?

    I assume a keyboard will pull up for typing an In-Reach message? In none of the reviews I’ve read has anyone actually tested the In-Reach function.

    A sat phone or an In-Reach device normally will not work from inside a vehicle since they need a direct line of site to the Iridium satellites. With a sat phone you can hook up an external antenna. Is there an external antenna to use with the Tread so the In-Reach will work from inside of a vehicle?

    How are you liking it now that it’s been a couple of months since your write up? Veteran’s Canteen Service has a sale going right now plus 20% off and the Overland Edition would be $1,013.59. An an In Reach 2 mini is $311 with code TY20. I’m definitely thinking about the Overland for on and Offroad driving, and love that it can show private & public land for hunting season, and forest roads.

    Thanks for the detailed write-up Ryan! I just ordered this yesterday for a trip this summer from the Gulf Coast to the Beaufort Sea. Can’t wait to take advantage of all the way points that ioverlander has, as well as the ability to text while running around the Yukon.

    Nice review. I have been considering getting the earlier version but this looks much nicer. I use iOverlander a lot and cannot find much info on how this unit works with the app. Does it make available all the info on the app? Can you see all the pin and the associated description? How about check-ins?

    Wife and I have used our Garmin InReach Explorer+ devices for the last several years to stay in touch with the SMS/location features when one or both are out on wildland fire assignments or remote USFS/BLM work and they’re worth every penny. Definitely checking this out!

    Not true. You can side load applications to both the 8” and 10” versions. It is not officially supported by Garmin, but it is very simple to do. Search for “sideloading”

    Instead of using the suction cup would it be fairly easy to attached a Ram mount or something similar to the magnetic charger and arm in order to bolt it to an installed dash like what ICS offers?

    I have mine mounted using Ram mounts. You’ll need the larger c-Size 1.5” ball and arm. Ball Mount: RAM-238U and Double Socket Arm (medium): RAM-201U

    It is heavy (at least the XL) so I had to move it lower to my Rago Fabrications center console molle bridge. But this keeps it lower but I can still glance at it and it doesn’t block my view. I had it installed on the Expedition Essentials T4RPAM mount but it was too heavy and blocked the top vents.

    Awesome review! I picked up the 10” Tread Overland XL a few weeks back and it’s a huge upgrade from the Overlander and InReach mini combo.

    The 10” is massive but I really like the larger screen to see more of the map and for quicker glances while driving. But to your point it does take up a lot of space on the dash.

    The internals have definitely been upgraded from the Overlander so the whole UI and user experience (I’m a UX Designer by day so this stuff is important to me lol) is faster and more efficient. Just navigating around menus and the actual maps are greatly improved.

    At first I was torn with having the InReach mini as a separate device. It’s a negative to have to charge a separate device but it’s also nice if I just want to take that with me (like on a hike) and not have to carry the larger Overlander (before) or the (even larger) Tread Overland XL. Additionally you can’t easily share the InReach subscription across multiple devices. There’s a process (that you need an internet connection for) to switch the subscription from device to device. So that’s probably not something you’ll be able to do in the field. You’d probably be best served with 2 separate subscriptions, one for the InReach mini and one for the Tread, but that’s extra cost per month. I’m sticking with the single subscription and using the built-in InReach on the Tread for now but will hold on to the InReach mini for now.

    One bummer is that the Overlander supports up to 4 external cameras but the Tread Overland models do not. I have no idea why Garmin omitted this option, seems silly. But I have other cameras setup so it’s not a huge deal but would have liked this option to carry over to these new Tread models.

    I’m still playing around with the Tread Overland XL but it’s a great upgrade from the Overlander. As you mentioned it’s an investment but having an all in one device means less things to charge, tighter integration (the phone app integration rocks) and the offline storage is a huge benefit (yes you can have offline storage with Gaia, Overland Bound One, etc.).

    Once again great write up!

    Unfortunately you can’t share a single InReach subscription across multiple devices. You need to switch the subscription to your active device. The process is easy to do on the Garmin Explore website, it takes 10-15 minutes to transfer the service from device to device. But this is something you will probably need to do at home or at a location with a solid internet connection.

    I understand why Garmin does this but it’s annoying. It would be nice to have a multiple device subscription plan and maybe pay a couple of bucks extra a month for the second device then have to have an individual subscription per device.

    I had to do the process above when i switched over from my InReach mini and Overlander combo to the Tread Overland XL. I’m still keeping the InReach mini but it’s not in use at the moment.
