A car GPS will route a loaded semi straight into a low bridge, a weight-restricted road, or a turn no 53 foot trailer can make. A real truck GPS does the opposite. It takes your height, weight, length, and load type, then builds a route that legally and physically fits your rig. That single difference is why owner operators, fleet drivers, and weekend RV haulers buy a dedicated unit instead of leaning on a phone app.
We looked at the truck navigators most truckers actually run today, from Garmin’s dezl OTR line to Rand McNally’s TND and OverDryve series. We weighed truck-specific routing accuracy, screen size and glance readability, how current the road and restriction data felt, live traffic and weather, and how well each one held up to daily cab use. Here are the seven that earned a place, ranked best first.

1. Garmin dezl OTR800 8-inch Trucking GPS Navigator: Best Overall
The Garmin dezl OTR800 is the unit we kept coming back to. The 8-inch screen hits the sweet spot for a truck cab, large enough to read directions and lane guidance with a quick glance but not so wide it blocks your view. You enter a full truck profile, including height, gross weight, length, and whether you are carrying hazmat, and the dezl routes you around low clearances, weight-limited bridges, and roads that simply cannot take a tractor trailer. In our testing the warnings for upcoming sharp curves, steep grades, and narrow roads fired early enough to actually be useful.
Beyond routing, this is a genuine trucker workstation. It logs IFTA mileage by jurisdiction, tracks service and hours-of-service breaks, shows truck and trailer services along your route, and helps you find parking and weigh stations. Paired with the Garmin Drive app you get live traffic and weather pushed to the screen. The honest weakness is size. On a smaller cab or a tight windshield the 8-inch unit can feel bulky, and you really want a solid mount because the included suction cup can struggle with the weight over rough roads. If screen real estate matters to you, this is still the one to beat.
- Large 8-inch glass display that stays readable at a glance in a bright cab
- Custom truck routing using your height, weight, length, and hazmat profile
- Garmin Drive app pairing for live traffic, weather, and smartphone alerts
Pros: Excellent truck-specific routing with reliable bridge and weight warnings; Big bright screen is easy to read without taking eyes off the road; Trucker tools like elevation, IFTA mileage logging, and load-to-dock parking
Cons: The 8-inch size needs a sturdy mount and takes up real windshield space; Map updates over Wi-Fi can be slow on the first large download
2. Garmin dezl OTR1000 10-inch Trucking GPS Navigator: Biggest Screen
If you want the most screen you can reasonably fit in a cab, the Garmin dezl OTR1000 delivers a 10-inch HD display that is genuinely easier on the eyes during long hauls. The standout is the split-screen, which lets you keep the live map on one side and the upcoming turn list or trip details on the other, so you are never guessing what comes after the next exit. The truck routing is the same proven Garmin engine, taking your full rig profile and steering you clear of low bridges, weight limits, sharp curves, and roads that are not built for a big truck.
It carries the full trucker toolkit too, including IFTA logging, truck-friendly points of interest, parking with photos and reviews, and elevation profiles for grades ahead. The trade-off is obvious the moment you mount it. Ten inches is a lot of glass, and in many day cabs or older trucks it simply eats too much of the windshield, or sits where it partly blocks your line of sight. The extra weight also asks more of the mount. For drivers with the dash space and a love of big displays, it is fantastic, but most people will be happier with the 8-inch OTR800.
- Huge 10-inch display with split-screen so you see map and turn list together
- Detailed truck routing with directional, narrow-road, and grade warnings
- Pairs with Garmin Drive app for live traffic, weather, and message alerts
Pros: The 10-inch screen makes lane guidance and exit info effortless to read; Split-screen view keeps the next maneuver visible at all times; Same strong truck routing and trucker tools as the rest of the dezl line
Cons: The 10-inch size is too large for many smaller cabs and windshields; Heavier unit puts more strain on the mount on rough roads
3. Garmin dezl OTR700 7-inch Trucking GPS Navigator: Best Value
The Garmin dezl OTR700 is the dezl line distilled into the most practical size for the widest range of trucks. You still get the same custom truck routing that uses height, weight, length, and load type to keep you off restricted roads and away from low clearances, plus the warnings for tight curves, steep grades, and narrow roads. For a lot of drivers the 7-inch screen is the right call, because it slips into a cab where the 8 and 10-inch models feel intrusive, and it is light enough that the mount holds steady on broken pavement.
It keeps the important trucker features, including IFTA jurisdiction mileage, hours-of-service break reminders, truck and trailer service listings, and parking with crowd-sourced reviews. Pair it to the Garmin Drive app and you add live traffic and weather. The honest limitation is the screen itself. After running an 8 or 10-inch unit, the 7-inch view can feel cramped, and split data like a long turn list is harder to take in at speed. It also skips the integrated dash cam. If you want maximum routing capability without dominating your windshield, this is the smart pick.
- Compact 7-inch screen that fits more cabs and windshields than the larger models
- Full custom truck routing with bridge height and weight restriction alerts
- Trucker tools including IFTA logging, break planning, and truck parking finder
Pros: Brings the dezl truck routing to a smaller, easier-to-place size; Strong feature set for the money compared to bigger dezl units; Lighter unit is gentler on the mount and easier to reposition
Cons: 7-inch screen feels small if you are used to a phone or tablet view; No built-in dash cam, unlike the dezlCam variant
4. Rand McNally TND 750 7-inch Truck GPS: Best for Pro Drivers
Rand McNally has been making trucking road atlases for generations, and the TND 750 leans on that commercial routing pedigree. Enter your truck dimensions, weight, and load details and it builds routes shaped around real commercial road data, with clear alerts for low bridges, weight-restricted roads, and turns that will not work for a big rig. The 7-inch screen is a good fit for most cabs, and the routing detail on freight corridors and truck-legal roads is a real strength for drivers who live in their truck.
The bigger draw for many pros is the ecosystem. The TND 750 plays nicely with Rand McNally’s ELD hardware and the DriverConnect platform, so your navigation, logs, and compliance tools live in one family. That said, the experience is where it gives ground to Garmin. The interface is busier and noticeably slower to respond, the maps do not feel quite as crisp, and updating software over Wi-Fi can be a slow, occasionally frustrating process. If you are already in the Rand McNally compliance world, the integration makes it worth the rougher edges.
- Built by a trucking road-data company with deep commercial route detail
- Truck routing tuned to your vehicle dimensions, weight, and load
- Pairs with Rand McNally ELD and DriverConnect for compliance tools
Pros: Strong commercial routing heritage and detailed truck road data; Works within the Rand McNally ELD and logbook ecosystem; Clear truck warnings for clearances, weight limits, and restrictions
Cons: Interface feels less polished and slower than Garmin's; Map and software updates can be fiddly to install
5. Garmin dezlCam OTR710 7-inch Trucking GPS with Built-in Dash Cam: Best With Dash Cam
The Garmin dezlCam OTR710 answers a question a lot of truckers ask, which is whether they can get truck navigation and a dash cam without cluttering the windshield with two devices. It packs an integrated camera into the same 7-inch dezl platform, so you get the proven custom truck routing, with height, weight, and load-aware paths and the usual low-bridge, weight, curve, and grade warnings, plus a camera quietly recording the road ahead. When it detects a hard stop or collision-type event it saves that clip automatically, which is exactly when you want footage.
As a navigator it behaves like the OTR700, complete with IFTA logging, parking finder, and break planning, so you lose nothing on the routing side. The compromise is the camera. An all-in-one unit is convenient, but the built-in cam does not match a dedicated dash cam on resolution, field of view, or features, and bundling navigation and recording into one device means a single failure takes out both. If a basic protective record is enough and you value one clean install, this is a smart two-in-one. Drivers who want serious video should pair a standalone dash cam with the OTR700 instead.
- Built-in dash cam records the road so you do not need a separate unit
- Same custom truck routing as the dezl OTR700 with restriction alerts
- Saves footage automatically when an incident is detected
Pros: Combines truck navigation and a dash cam in one tidy device; Recorded footage can protect you in a dispute or claim; Full dezl truck routing and trucker tools included
Cons: Built-in camera is convenient but not as capable as a dedicated dash cam; Combining both functions in one unit creates a single point of failure
6. Rand McNally OverDryve 7 Pro Truck GPS Tablet: Best Connected Tablet
The Rand McNally OverDryve 7 Pro takes a different angle from the dezl units. Instead of a focused navigator, it is a tablet-style device that wants to be the hub of your cab. It still does the core job, building truck routes around your vehicle’s height, weight, and length and flagging low clearances and restricted roads, but it wraps that in extras like Bluetooth hands-free calling, music playback, a built-in dash cam, and connected weather and traffic. For a driver who wants one screen handling navigation, calls, and media, the all-in-one concept is appealing.
The cost of that ambition is focus. Trying to be a navigator, a phone, a media player, and a dash cam at once means the OverDryve can feel slower and less responsive than a unit that just navigates, and the interface has more going on than some drivers want at a glance. Several of the connected perks also work best with active subscriptions, which is something to weigh before you commit. As a do-everything cab companion it is interesting, but pure routing purists will still prefer a dedicated dezl.
- Tablet-style design adds music, hands-free calling, and an app feel
- Truck routing with clearance and restriction warnings for your rig
- Built-in dash cam and SiriusXM-ready connected features
Pros: Does more than navigate, with media and hands-free calling built in; Includes a dash cam and a familiar tablet-style interface; Truck routing plus weather and traffic add-on options
Cons: Jack-of-all-trades approach can feel slower and less focused than a pure GPS; Some connected features lean on subscriptions to be fully useful
7. Garmin RV 895 Camper and Truck GPS Navigator: Best for RV and Hauling
The Garmin RV 895 is the pick for drivers whose big rig is an RV, a camper, or a heavy tow setup rather than a commercial tractor trailer. You set up a profile with your vehicle’s dimensions and weight, and it routes you to avoid roads, bridges, and turns that do not suit a large vehicle, with the same kind of clearance and restriction awareness that makes truck GPS units worth owning. The 8-inch screen is bright and easy to read, and the maps are detailed, with strong lane guidance heading into complex interchanges.
Where it shines is the lifestyle content. It carries deep directories of campgrounds, RV parks, dump stations, and traveler services, which is exactly what you want when hauling a fifth wheel cross country. The flip side is that it is built around RV and camper use, not freight. It does not include commercial tools like IFTA jurisdiction logging, hours-of-service tracking, or hazmat profiling, so an over-the-road trucker is better served by a dezl. For RV owners and serious haulers, though, the RV 895 is purpose-built and a pleasure to drive with.
- Custom routing for RVs, trailers, and larger vehicles by size and weight
- 8-inch bright touchscreen with detailed maps and lane guidance
- Built-in directories for campgrounds, services, and trailer-friendly stops
Pros: Excellent for RV haulers, towing, and oversized personal rigs; Large readable screen with strong size-aware routing; Rich campground, park, and service points of interest
Cons: Tuned for RV and camper use rather than heavy commercial trucking; Lacks commercial extras like IFTA logging found on the dezl line
Frequently Asked Questions
Do I really need a truck GPS, or can I just use my phone?
A phone navigation app routes for a car. It does not know your truck is 13 feet 6 inches tall, runs 80,000 pounds, or pulls a 53 foot trailer, so it will happily send you under a low bridge, onto a weight-restricted road, or into a turn you cannot physically make. A dedicated truck GPS lets you enter your height, weight, length, and load type, then builds a route that actually fits your rig and warns you about clearances, grades, and sharp curves ahead. For anyone driving a real truck, that safety margin is the whole point.
What screen size is best for a truck GPS?
It depends on your cab. The 7-inch units, like the Garmin dezl OTR700, fit the widest range of trucks and are easy to place without blocking your view. The 8-inch models, such as the dezl OTR800, are a popular middle ground that stay easy to read at a glance while still fitting most windshields. The 10-inch dezl OTR1000 gives you the most screen and a useful split-view, but it is too large for many smaller or older cabs. Measure your available windshield space before you commit to a bigger display.
How do truck GPS units keep their maps and restrictions up to date?
Most modern truck navigators, including the Garmin dezl line, update over built-in Wi-Fi. You connect the unit to a network, download new map and road-restriction data, and install it directly on the device, often at no extra charge for the life of the product on Garmin units. Live traffic, weather, and some services come through a paired smartphone app. Keeping maps current matters more on a truck than a car, because bridge heights, weight limits, and new road restrictions change, and stale data can route you somewhere you should not be.
Will a truck GPS work for an RV or fifth wheel?
Yes, and Garmin even makes a dedicated RV line for exactly this. A commercial truck GPS like the dezl will route your RV safely if you enter the right dimensions, but the Garmin RV 895 is purpose-built for campers and haulers, adding directories for campgrounds, RV parks, and dump stations that an over-the-road trucker does not need. If your big vehicle is recreational, the RV unit fits your trips better. If it is a working commercial truck, a dezl with IFTA logging and hours-of-service tools is the stronger match.
Can a truck GPS help with IFTA mileage and logs?
Some can. The Garmin dezl OTR models track your mileage by state and province, which makes IFTA fuel-tax reporting far less painful, and they include break planning aligned with hours-of-service rules. Rand McNally goes a step further for fleets by pairing units like the TND 750 with their own electronic logging device hardware and the DriverConnect platform, so navigation and compliance live together. If logging and tax reporting are a regular headache, prioritize a unit with these commercial tools rather than a basic navigator.
Our Verdict
For most truckers, the Garmin dezl OTR800 is the one to buy. It blends accurate truck-specific routing, a bright and readable 8-inch screen that fits most cabs, and a deep set of trucker tools like IFTA logging and parking search into a unit that simply works day after day. If you want the same capability in a smaller, easier-to-mount package, the Garmin dezl OTR700 is our runner up and the best value of the group. Pick the OTR1000 if you crave the biggest screen, the dezlCam OTR710 if you want a built-in camera, the Rand McNally TND 750 if you live in the Rand McNally compliance ecosystem, and the Garmin RV 895 if your rig is a camper or heavy tow. Whatever you choose, give your truck a navigator that actually knows it is a truck.
