What are the differences between the Garmin Montana 700 Series and 710 Series?
Share
If you’re in the market for a large-screen Garmin GPS for walking, hiking, trail riding or multi-day expeditions, you’ve likely looked at the Garmin Montana range. The recently released Garmin Montana 710 series brings a handful of important upgrades over the original 700 series — and understanding these changes will help you choose between the 710, 710i and 760i.
This review is based on a hands-on test walk by Jon Monks, from GPS Training, in the Simonside Hills, Northumberland, using the new Montana 710. Here’s what’s new, how it compares, and which model might suit you best.
Key Upgrades from the Montana 700 Series to the 710 Series
The Garmin Montana 710 series replaces the 700, 700i and 750i, with four notable improvements:
Improved Battery Life
-Up from 18 hours to 24 hours – a 30% increase.
- More endurance for multi-day trips without charging.
USB-C Charging Port
- The old micro-USB has been replaced by modern USB-C for faster, more reliable charging and data transfer.
- Still compatible with older computers via a USB-A to USB-C adapter.
Direct Map Downloads
- You can now download TopoActive maps directly to the unit, including overseas coverage.
- Garmin offers an optional worldwide subscription service (OS mapping still purchased separately).
Increased Internal Memory
- Doubled from 16GB to 32GB.
- Reduces risk of running out of space when updating maps or adding large datasets.
Model Comparison – 710 vs 710i vs 760i
| Model | Road Navigation (City Navigator) | Two-Way Satellite Messaging (inReach) | Built-in Camera | Best For |
|---|---|---|---|---|
| Montana 710 | ❌ | ❌ | ❌ | Walkers & hikers who don’t need inReach or road routing. |
| Montana 710i | ✅ | ✅ | ❌ | Multi-use adventurers who want off-grid communication and motorbike/vehicle routing. |
| Montana 760i | ✅ | ✅ | ✅ (8MP) | Expedition users who want an all-in-one GPS with photos geo-tagged. |
A quick guide:
- 710 – Base model, most popular for walkers.
- 710i – Adds inReach satellite messaging and City Navigator road maps.
- 760i – All of the above plus an 8MP camera for geo-tagged images.
Mapping Options – 1:50k vs 1:25k OS Maps
While the Montana comes preloaded with Garmin TopoActive maps, UK users will want Ordnance Survey mapping for full rights-of-way detail.
- 1:50k OS Map Card – Cheaper, includes all footpaths and bridleways.
- 1:25k OS Map Card – Adds permissive paths, open access land, and field boundaries. Best for National Parks and areas with complex access.
Tip: Buy mapping when you purchase the GPS to get discounted bundle pricing.
Navigation Types – Route vs Track vs Course
- Route – A series of waypoints joined together, with beeps at each waypoint. Best for planned day walks.
- Track – A breadcrumb trail, often used for long-distance trails with waymarking. Beeps if you go off track.
- Course – Silent navigation unless you go off course. Created automatically when sending from Garmin Connect or Explore app.
Knowing which you’ll use most will help you choose the best planning method and device setup.
Handling & Performance in the Field
- Large 5-inch touchscreen – Excellent visibility, even in bright sunlight.
- Glove-friendly operation – Works well in winter, even without “glove mode” enabled.
- Durable build – Gorilla Glass screen and IPX7 waterproofing.
- Carrying tip – Use a Garmin carry case on your rucksack strap to avoid pocket bulk and protect the unit.
Advantages of a Large-Screen GPS
- See 3–7km ahead without zooming or panning.
- Easier to adapt your route mid-walk.
- Better situational awareness for both walkers and riders.
The trade-off is size and weight, so a good carrying solution is important.
Cold Weather & Battery Test Results
In sub-zero Northumberland conditions, the Montana 710 still had 67% battery remaining after 4 hours 35 minutes of use, with screen brightness up and track recording on. That’s a strong real-world result for winter walking.
Verdict – Should You Upgrade?
If you already own a Montana 700 series, the 710’s extra battery life, faster USB-C charging, double storage, and direct map downloads make it a meaningful upgrade — especially if you’re running short on space with large maps.
If you’re buying new:
- Walkers who don’t need satellite comms should choose the 710.
- Mixed-terrain adventurers, bikers or those heading off-grid should consider the 710i for inReach safety.
- Expedition users wanting photos without extra kit should go for the 760i.
