Garmin eTrex 32x Review

Overview

The Garmin eTrex 32x is a compact, button-operated handheld GPS navigator aimed at hikers, backpackers, and anyone who wants a dedicated device that works independently of a phone or cell signal. It comes preloaded with Garmin’s TopoActive maps, adds a 3-axis tilt-compensated compass and barometric altimeter over the cheaper 22x sibling, and runs on a pair of standard AA batteries for up to 25 hours. One important caveat up front: Garmin released the eTrex Touch in September 2025 as the current-generation eTrex, so the 32x remains available but is no longer the latest model. That doesn’t make it a bad buy — just worth knowing before you pull the trigger.

Performance

Satellite Reception & Accuracy

The eTrex series uses a patch antenna, which means best reception is theoretically achieved when held horizontally — but real-world track recordings are generally very accurate even when the device is attached to a backpack and the antenna isn’t perfectly positioned.

In a side-by-side comparison against a GPSMAP 66i, a Fenix 6x Pro Solar, and an iPhone 11,

the eTrex 32x’s GPS fix came in close to the more expensive GPSMAP 66i and Fenix 6x, and it performed slightly better than the iPhone 11 while almost always outperforming the older eTrex 20.

That’s a respectable showing for a budget-tier handheld. The one satellite-system gap worth noting:

the eTrex 32x supports GPS and GLONASS but not Galileo,

which newer competing devices have started to include.

Battery Life

Garmin’s claimed 25-hour runtime proved accurate in general testing, and using lithium batteries can extend that — with closer to 30–35 hours seen in practice.

The universal AA format is one of this device’s most practical features:

it’s easy to carry spares, and you can find them at almost any gas station in a pinch.

One minor annoyance:

the battery meter only shows four 25% notches — no numeric percentage, which would be far more useful on a multi-day trip.

Maps & Memory

The preloaded TopoActive maps cover routable roads and trails, and the included Garmin topo maps have much better trail coverage than they did a few years ago. The 8 GB of internal storage sounds generous until you realize only about 90 MB remains available after the pre-installed TopoActive map consumes most of it. If you plan to load additional maps or data, you’ll need a microSD card. Some users have also reported that certain microSD cards aren’t recognized correctly — the fix is usually ensuring the card is formatted properly and is class 4–10, up to 32 GB.

Interface & Ergonomics

The buttons follow the same layout as most Garmin GPS units — if you’ve used a Garmin device before, it will feel familiar, and after a few minutes it’s fast to operate.

The joystick-and-button scheme is a genuine advantage in cold or wet conditions: physical buttons work with gloves where a touchscreen simply doesn’t. That said,

many users accustomed to modern interfaces find the joystick and T9-style text entry cumbersome compared to a touchscreen.

The unit’s build feels appropriately tough —

wrapped in a slightly softer plastic that’s easy to grip, with buttons that provide a subtle tactile click.

Connectivity

This is where the 32x starts to show its age. The device connects only via ANT+, not Bluetooth or Wi-Fi, and cannot link to apps like Garmin Connect or Garmin Messenger. That means you can’t transfer files wirelessly from your phone — you need a computer or a microSD card to get routes and waypoints onto the device. Garmin BaseCamp handles that workflow for free, but it adds friction that competing devices at a similar price no longer require.

Pros & Cons

Pros

• AA batteries: easy to source, swap on trail, and use with lithium cells for extended life
• Preloaded TopoActive maps — no ongoing subscription required
• Physical buttons work reliably with gloves and in heavy rain

• Position available very fast after switching on the device

  — quicker cold-start than the GPSMAP 64sx in testing
• IPX7 waterproofing — submersible to 1 meter
• 3-axis tilt-compensated compass works when stationary, unlike GPS-derived heading
• Rugged build; doesn’t demand the careful handling a smartphone does
• Stable, proven software that just works

Cons

• The interface feels like it’s from a 1998 flip-phone — functional but genuinely dated
• ~90 MB of free internal storage after maps; microSD is effectively mandatory
• ANT+ only — no Bluetooth or Wi-Fi means no wireless file transfers or phone sync
• Mini-USB connector in an era of USB-C everywhere
• No Galileo satellite support; newer units cover more constellations
• Battery indicator is a 4-bar gauge with no percentage display
• No track-deviation alert when you stray off route

Who Should Buy This

The eTrex 32x is the right tool for hikers and backpackers who regularly travel in areas with no cell coverage and want a dedicated navigation device that doesn’t depend on a phone battery or a data plan. AA batteries, preloaded TopoActive maps, physical buttons that work with gloves, and a proven software platform make it solid in the field. It’s also a smart choice for anyone who’s already in the Garmin ecosystem and wants seamless BaseCamp integration. If you mostly hike in areas with decent cell coverage, a phone running Gaia GPS or Caltopo will give you a better screen and more features for less money. And if you’re open to spending more, the newer eTrex Touch or a GPSMAP 65s adds Bluetooth, Wi-Fi, and multi-constellation GNSS support — meaningful upgrades on a long trip.

Verdict

The eTrex 32x earns its reputation as a reliable, no-fuss backcountry GPS. The combination of AA batteries, IPX7 waterproofing, glove-friendly buttons, and preloaded topo maps covers the fundamentals well, and the satellite performance holds up against pricier hardware. The connectivity story — ANT+ only, mini-USB, no phone sync — is genuinely frustrating in 2025 and pushes serious users toward newer options. If you find it at a significant discount, it’s still a capable trail companion; at full price, compare it carefully against the current eTrex Touch generation before committing. Rating: 7.5/10.
