Our Picks at a Glance
How To Choose The Best Truck GPS Units
Picking a truck GPS means looking past the screen size and focusing on the routing brain inside. A unit designed for cars will happily send a fully loaded rig down a road it has no business being on. Here is what separates a professional tool from a toy.
Truck-Specific Routing Is The Core Feature
This is the software that takes your truck’s height, weight, and length into account when plotting a route. It flags upcoming bridge heights, weight limits, sharp curves, and steep grades before you commit to a road. Without this, you are navigating blind.
Screen Size And Arrival Planning
A bigger display makes it easier to glance at complex interchanges, but the real value is in the arrival view. High-resolution satellite imagery of loading docks, truck entrances, and security gates means you know exactly where you’re backing into before you get there. This is a feature you will use on every delivery.
Connectivity And Updates
Think about how the unit stays current. Built-in Wi-Fi lets you update maps and software without plugging into a computer. Bluetooth pairing with a smartphone app open up live traffic, weather overlays, hands-free calling, and smart notifications. Some units even work with subscription-free ELD logging for your hours of service.

In‑Depth Reviews
1. Garmin dezl OTR800
Our pick — 4.5★ from 600+ verified ratings; the strongest balance of quality and price.
The big-screen flagship with the most praised functionality for over-the-road work.
The OTR800’s 8-inch touchscreen is the star here — it’s bright, crisp, and can be flipped to landscape or portrait view to match how you sit in the cab. That size advantage is huge in practice, That’s a 33% larger screen than the 6-inch OTR610, reducing squinting at complex interchanges., which means less squinting at complex interchanges. The display earns its keep with an intuitive layout that shows the information that matters most while you drive.
Functionality is what wins people over, and it’s easy to see why. Custom truck routing uses your truck’s size and weight to alert you to upcoming bridge heights, weight limits, sharp curves, and steep grades. The industry-best load-to-dock guidance shows potential loading zones or storage lots as you approach your destination, and a preloaded Truck & Trailer Services directory filters stops by brand or amenities. Owners note it safely routes a 53-ft trailer and finds truck stops and rest areas reliably. The powered magnetic mount with a heavy-duty suction cup makes daily mounting feel solid, and you can also screw it down or adapt it to a RAM mounting system with the included 1” ball adapter.
Voice control lets you talk to the navigator while keeping your hands on the wheel, and it works with a Garmin eLog compliant ELD (sold separately) for subscription-free Hours of Service recording without needing a smartphone. The fairness note: it runs on a 2-hour battery, boots slowly on a cold start, and uses micro USB instead of USB-C. Buyers report it’s an excellent overall unit, but the slow 20-min cold boot and minimal memory cause rare app crashes — Owners mention a 5-star experience 99% of the time, with rare 10+ minute restarts after lockups., with occasional 10+ minute restarts if it locks up.
What Owners Rave About
- Large 8” screen is bright and crisp for easy in-cab viewing
- Load-to-dock guidance helps find loading zones at delivery points
- Multiple mounting options include a powered magnetic mount
- Works with subscription-free ELD for hours of service tracking
What To Expect
- A 2-hour battery means it lives plugged in on the dash
- Slow cold boot and limited memory can cause rare app crashes
- Charges via micro USB instead of the more modern USB-C
Reach for this if: you run a 53-foot trailer over-the-road and want the largest, most feature-complete Garmin display with load-to-dock guidance.
Look elsewhere if: you need a unit that boots instantly every morning and can’t tolerate an occasional slow restart.
2. Rand McNally TND 750
A 7-inch truck navigator with a built-in dash cam at a budget-friendly price.
The TND 750 is a sixth-generation TND truck GPS that packs a lot into a value price point. The 7-inch LCD screen is a great size and can be read easily even when it’s sitting on the dash, and it’s customizable based on your truck’s size, weight, and cargo. For the price, you’re getting a navigator and a dash cam in one unit — a combination that usually costs significantly more.
Dynamic weather overlays display the current forecast across your route, showing precipitation, temperature, and wind speed. The 3D buildings and landmarks help you follow detailed routes, and Bluetooth lets you connect your smartphone for hands-free use. The dash cam adds an eyewitness on the road without you having to buy a separate device. One note: this is a renewed unit, so it’s been inspected and tested to work like new, but it’s not fresh from the start.
The honest trade-off is in the routing software. Some owners find the search function not the most intuitive, and occasionally the routes are a little off. A few report it won’t recalculate for 30 miles down the road after you leave a chosen route, which can add hundreds of miles in some cases. It’s a capable unit for the money, but the Garmin units above it hold a clear edge in routing intelligence.
Smart Budget Pick: You get a navigator and dash cam together without paying premium prices.
The Fine Print: Routing recalculations can be slow and occasionally send you the long way around.
3. Garmin dezl OTR610
A lightweight 6-inch unit that leads with high-res satellite views for confident arrivals.
At just 6.17 ounces, the OTR610 is the featherweight of the group, yet it doesn’t cut corners on the features that matter. Building quality is the thing everyone raves about, and it’s easy to see why: the 6” multi-touch glass display is bright and crisp, and owners consistently call it easy to set up and use. The compact size — 6″L x 0.7″W x 3.4″H — makes it a natural fit for tighter cabs without sacrificing readability.
The standout here is leading-edge arrival planning with BirdsEye Satellite Imagery, which provides high-resolution aerial views of loading docks, truck entrances, and security gates. You can see exactly where you’re backing in before you get there. The route planner feature helps you review complete routes and decide on the best places for fuel stops, comfort breaks, and overnight stays. Truck & Trailer Services directory filters by brand or amenity, like “Love’s” or “Showers.”
PrePass notifications help you save time with on-screen weigh station and bypass alerts — when paired with the dēzl app on your smartphone via Bluetooth. It comes with integrated map updates of North America covering the U.S., Mexico, Canada, U.S. Virgin Islands, Cayman Islands, and Bahamas. Owners love that it helps avoid bridges that are too low and tells truckers where they can safely go. Unlike some rivals, if you set the zoom to how you like it, it stays there, and it shows STAA routes on the screen without irrelevant red lines.
Standout Strengths
- BirdsEye satellite views make loading dock arrivals easier
- Light at 6.17 ounces for easy mounting and handling
- PrePass notifications for weigh station bypass alerts
- North America map coverage includes Mexico and Canada
Owner Notes
- Some customers note it stops working after a month of use
- Addresses sometimes don’t show up in searches
- Best results come from pairing with the smartphone app for map updates
Who it beats: owners switching from Rand McNally find the zoom stays put and STAA routes display cleanly without clutter.
Who it doesn’t: drivers who want a larger screen for complex interchanges should look at the 7 or 8-inch models.
4. Garmin dēzl OTR620 Bundle
A 7-inch TomTom that owners say outperforms Garmin on truck routing in Europe.
The Go Expert Plus 7 is built for both bus and truck use, and at 730 g it’s a substantial unit that feels solid in the cab. The 7-inch HD touchscreen with Lane Assist is designed for clear guidance, and Bluetooth, USB, and Wi-Fi connectivity options keep it flexible. Owners transitioning from other brands report it avoids national roads and offers image quality and speed they rate 10/10, with excellent traffic data and precise jam end times.
The traffic data is genuinely excellent — it reports precise jam ends and keeps your ETA updated even when you hit delays. Bluetooth replaces a hotspot for connectivity, which simplifies setup. Route alternatives are easy to access, and the speed alert data is a strong feature. A smart note from owners: weight limits aren’t auto-adjusted, so you’ll want to set your truck’s weight manually (one owner set 30t for the Cologne zoo bridge).
You get dependable trucking routes on long trips, but experienced owners consistently advise bringing basic route knowledge. While Owners rate the routing about 95% reliable, though it can still miss local restrictions., it can still send a >7.5t truck through a prohibited city center near León in France if you don’t watch it. The built-in battery comes in the box, so you can easily move it between vehicles without extra cables.
Traffic Ninja: Owners rave about precise jam end times and accurate ETAs that update through delays.
Smart Owner Tip: Set your vehicle weight manually — it won’t auto-adjust, but owners rate it 95% reliable with basic route knowledge.
5. TomTom Truck Sat Nav GO Expert
A 6-inch TomTom with 4X faster responsiveness and professional large vehicle routing.
The GO Expert is built for professional large vehicle navigation, receiving custom routes and POIs for your bus, truck, or coach. It delivers live alerts for bridge heights, ADR tunnels, UN Class restrictions, and more — critical safety intel for anyone hauling hazardous materials. The 6/7 inch HD screen is among the highest resolution on the HGV sat nav market, paired with a powerful speaker for clear guidance.
The defining spec here is 4X faster responsiveness, with a modern interface and map view that swipes, zooms, and uses features smoothly on an ultra-responsive touchscreen. That speed makes a real difference when you’re in traffic and need to change your route quickly. TomTom Traffic keeps you ahead of congestion with jam tail warnings, and you get 1 year of speed camera alerts included.
Owners who use it for ADR cistern hazardous material transport rate it spectacular, and It’s proven reliable for months of use across domestic and international routes.. The recurring gripe is administrative: some report the maker tries to sell a subscription and in one case billed without consent. And like any electronics, units can fail over time — One owner’s unit stopped booting after 2 years and 6 months of use.. The 1-hour battery means it stays plugged in.
Built For Hazmat
- Live alerts for ADR tunnels and UN Class restrictions
- 4X faster responsiveness for quick reroutes
- 1 year of speed camera alerts included
- World maps with live restriction warnings
Honest Warnings
- The 1-hour battery means constant dash power
- Some shoppers say unwanted subscription billing attempts
- Units can fail after years of heavy use
Grab it for: ADR and hazmat hauls where live tunnel and UN Class restriction alerts are non-negotiable safety features.
Think twice if: you detest subscription upsells — keep an eye on your statements after purchase.
6. Rand McNally TND 1050
A rugged 10-inch tablet-style navigator with Gorilla Glass and a removable guard.
The TND 1050 is the giant of the group at 10.5″L x 6.5″W x 1.2″H, and it’s built tough for the road. The heavy-duty Gorilla Glass screen with a removable protective guard is engineered to withstand the rigors of life on the road, and three strong mounting options keep it secure even on the bumpiest routes. This is the unit for drivers who want tablet-sized maps they can read from across the cab.
Rand Navigation 2.0 claims 33% more truck-specific road data than competing GPS platforms., customizing routing for your rig’s size, weight, and cargo. The integrated dash cam simplifies driver and vehicle inspection reports, while receipt tracking keeps expenses organized. The 5-hour battery is the best in this lineup, meaning you can unplug it and use it as a portable tablet when you’re parked or walking around the yard.
You get WiFi for smooth map updates and a USB port to charge your phone or tablet on the go. The magnetic charging dock base and removable tablet design make it feel modern. Owners love how detailed the turn-by-turn directions are, and the road atlas feature is a bonus. The honest note: at this size, it’s slightly large on the windshield, and graphics are a bit duller than the Garmin units. The recurring reliability critique is that Some units crash after two years of use, per owner reports., and one owner reports it can send you 20 miles back for a nearby gas station.
Built Like A Tank
- Gorilla Glass screen with removable protective guard
- 5-hour battery — the best in this lineup
- 33% more truck-specific road data claimed
- Integrated dash cam and receipt tracking
Owner Reality
- At 10.5 inches, it’s large on the windshield
- Graphics are duller than Garmin units
- Some units reported crashing after two years
Reach for it if: you want the biggest map view possible with a tough screen and a battery that lasts between stops.
Look elsewhere if: you prefer razor-sharp display graphics or a more compact footprint on your windshield.
