Up-to-date expert picks
A car GPS can get a trucker into serious trouble — low bridges, weight-restricted roads, and truck-prohibited routes don't care about your ETA. Garmin's dezl line is built specifically for commercial trucking: you enter your rig's height, weight, length, and hazmat class once, and every route respects those limits, with warnings for steep grades, sharp curves, and truck speed limits. Based on specifications, professional reviews, and trucker feedback, these are the best Garmin truck GPS units in 2026. Check current pricing before buying — these are pro tools with pro price tags.

Garmin dezl OTR710
Best Overall Truck GPSThe OTR710 is the sweet spot of the dezl line: a 7-inch screen big enough to read at a glance without dominating the windshield, full custom truck routing, and the truck & trailer services directory with 30,000+ repair and fuel stops. Based on specifications and trucker feedback, it's the unit most owner-operators buy — the right mix of screen size, features, and price.
Load-to-dock guidance with BirdsEye satellite imagery is the standout feature: aerial views of the destination help you find the right loading dock on the first try instead of circling the industrial park. Pair it with the Garmin Drive app for live traffic and weather over your phone's connection.
Pros
- Ideal 7-inch size
- full truck routing
- BirdsEye dock imagery
- huge services directory
- ELD-ready.
Cons
- Premium price
- some advanced features need the smartphone app
- address entry must be precise.
Full specifications
- 7-inch high-resolution touchscreen
- Custom truck routing (height, weight, length, hazmat)
- Preloaded maps of North America with free lifetime updates
- BirdsEye satellite imagery for load-to-dock guidance
- Bluetooth hands-free calling; voice control
- ELD-compliant when paired with Garmin eLog

Garmin dezl OTR810
Best Large-Screen Truck GPSThe OTR810 is the OTR710's big-screen sibling: same truck-routing brain, same feature set, but an 8-inch display that's meaningfully easier to read at a glance — a real safety advantage when you're checking the next turn at highway speed. Truckers who've used both consistently say the extra inch matters more than it sounds.
The tradeoffs are price and dash real estate: it's the most expensive non-dashcam dezl, and the larger unit needs a solid mount placement that doesn't block your view. If your eyesight isn't perfect or you just want maximum readability, it's worth it.
Pros
- Excellent readability
- full dezl feature set
- great for long-haul drivers
- strong mount included.
Cons
- Expensive
- large footprint on the windshield
- heavier than smaller units.
Full specifications
- 8-inch high-resolution touchscreen
- Custom truck routing with vehicle profiles
- BirdsEye satellite imagery; truck & trailer services directory
- Preloaded North America maps; free updates
- Bluetooth, WiFi, voice control

Garmin dezl OTR610
Best Compact Truck GPSNot every cab has room for a 7–8 inch screen, and not every budget stretches to one. The OTR610 brings genuine custom truck routing — the core safety feature — in the smallest, most affordable dezl package. Regional and short-haul drivers who know their routes but want truck-aware guidance and restriction warnings get everything they need here.
You give up BirdsEye satellite imagery and some screen comfort versus the bigger models, and the 6-inch display demands a closer mount. But the routing engine — the part that keeps you off restricted roads — is the same.
Pros
- Most affordable dezl
- real custom truck routing
- compact for tight cabs
- free map updates.
Cons
- Smallest screen
- no BirdsEye imagery
- fewer premium extras than OTR710/810.
Full specifications
- 6-inch touchscreen display
- Custom truck routing (size/weight restrictions)
- Preloaded maps with free lifetime updates
- Truck speed limit warnings; sharp curve alerts
- Bluetooth hands-free; compact dash footprint

Garmin dezlCam OTR710
Best Truck GPS with Dash CamThe dezlCam merges two cab essentials into one mount: the full OTR710 navigator plus a 1080p dash cam that records continuously and auto-saves footage when its G-sensor detects an incident. For liability protection — the "it wasn't my fault" video — a dash cam is arguably as important as the navigation itself, and having it integrated means one power cable and one windshield footprint instead of two.
It costs more than the standard OTR710, and serious videographers will note a dedicated dash cam records better footage. But for set-and-forget incident documentation paired with top-tier truck routing, the integration is genuinely convenient.
Pros
- Navigation + dash cam in one device
- incident auto-save
- safety warnings
- single mount and cable.
Cons
- Pricier than OTR710
- dash cam quality trails dedicated units
- larger file storage needs a big microSD.
Full specifications
- 7-inch touchscreen + built-in 1080p dash cam
- Custom truck routing identical to OTR710
- Automatic incident recording (G-sensor triggered)
- Forward collision and lane departure warnings
- Compatible with Garmin BC backup cameras

Garmin dezl OTR1010
Biggest Screen for Team DriversThe OTR1010 is the flagship for drivers who want maximum screen: a 10-inch display that's readable from the passenger seat, making it ideal for team drivers and trainers. Same routing engine and feature set as the rest of the OTR line, just bigger — route overviews, junction views, and the services directory are all dramatically easier to scan.
It's the priciest dezl and needs careful mounting — a 10-inch unit can eat a serious chunk of windshield if placed poorly. This is a specialist tool for drivers who live in the cab; solo regional drivers don't need it.
Pros
- Huge, highly readable display
- full feature set
- great for team driving and training.
Cons
- Most expensive
- demands thoughtful mounting
- overkill for solo short-haul work.
Full specifications
- 10-inch extra-large touchscreen
- Custom truck routing with trailer profiles
- BirdsEye satellite imagery; services directory
- Preloaded maps with free lifetime updates
- Bluetooth, WiFi, voice control

Buying Guide: Choosing a Truck GPS
Custom truck routing is the whole point
Every dezl here routes around low clearances, weight limits, truck-prohibited roads, and hazmat restrictions based on the vehicle profile you enter. Set it up carefully the first time — accurate height, weight, length, width, and hazmat class — because the routing is only as good as the profile. Double-check the first few routes against your own knowledge of the area.
Screen size vs. cab space
Bigger screens are easier to read at a glance (safer), but they block more windshield. The 7-inch OTR710 is the consensus sweet spot; go 8–10 inches if your vision needs it or you team-drive, and 6 inches if your cab is tight or your budget is tighter. Whatever the size, mount it low and to the side — never in your direct forward sightline.
Map updates and traffic
All current dezl units include lifetime map updates (several per year) — install them over WiFi regularly, since road restrictions change. Live traffic and weather come via the Garmin Drive smartphone app over Bluetooth; the GPS doesn't have its own cellular connection, so keep your phone paired on the road.
ELD compliance
If you need electronic logging device compliance, Garmin's eLog system pairs with dezl navigators for hours-of-service tracking. It's a separate purchase from the GPS itself — factor it into your budget if you're an owner-operator handling your own compliance.
Frequently Asked Questions
Can I use a regular car GPS for trucking?
You shouldn't. Car GPS units don't know about bridge heights, weight limits, or truck-prohibited routes — following one in a semi can lead to fines, stuck trucks, or bridge strikes. A truck GPS costs more because it carries truck-specific map data and restriction databases.
Do Garmin truck GPS units work in Canada and Mexico?
Yes — current dezl models come preloaded with detailed North America maps covering the US, Canada, and Mexico, with truck restriction data for all three. Map updates are free.
How accurate is the truck routing?
Very good when your vehicle profile is accurate, but no GPS is infallible. Truckers report occasional odd reroutes, and new restrictions can lag behind map updates. Treat it as an expert co-pilot, not an infallible authority — posted signs always win.
Is the dash cam on the dezlCam good enough?
For incident documentation — absolutely. It records 1080p continuously and auto-saves on impacts. It won't match a premium dedicated dash cam for night quality or parking surveillance, but as an integrated "set and forget" witness, it does the job.
Conclusion
The Garmin dezl OTR710 remains the best truck GPS for most drivers — the right screen size, full truck routing, and a fair price. Go OTR810 for maximum readability, OTR610 to save money and dash space, dezlCam OTR710 to add incident video in the same mount, or OTR1010 if you want the biggest screen Garmin makes. Whichever you choose, set up your vehicle profile carefully, keep the maps updated, and check the current price on Amazon before buying.
