1. Garmin dezl OTR700: Top Pick
In our evaluation, the Garmin dezl OTR700 stands out for its robust truck-specific routing. It uses detailed map data to avoid low bridges, weight-restricted roads, and other hazards. Owner feedback consistently praises its ability to keep drivers on safe, legal routes. The 7-inch screen is bright and responsive, making it easy to glance at while driving.
However, its premium features come at a significant cost. If you rarely encounter complex restrictions or mainly drive familiar routes, a simpler GPS may suffice. The OTR700 is best for owner-operators and long-haul drivers who need reliable, custom routing every day.
- Custom truck routing based on height, weight, width, and hazardous materials
- 7-inch high-resolution display with glare reduction
- Built-in Wi-Fi for easy map and software updates
Pros: Excellent route customization for tractor trailers; Clear display readable in direct sunlight
Cons: Higher price point than basic models
2. Rand McNally TND 750: Best Value
Based on owner feedback, the Rand McNally TND 750 offers strong truck routing at a more accessible price. The built-in dash cam is a standout feature that can provide evidence in case of incidents. We compared its route calculations against the Garmin and found it generally reliable, though occasionally less detailed in rural areas.
Some users report the touchscreen responsiveness could be better, especially when cold. If you prioritize a smooth interface over an all-in-one dash cam, you might prefer the Garmin. The TND 750 is ideal for drivers who want a solid GPS with extra safety recording without breaking the bank.
- Integrated dash cam with automatic incident recording
- Truck-specific routing with real-time traffic
- Wi-Fi connectivity for map updates and traffic
Pros: Dash cam adds value and safety; Good balance of features and price
Cons: Interface can be slower than competitors
3. TomTom Trucker 620: Best for Europe
Our research shows the TomTom Trucker 620 excels in European coverage, with detailed truck restrictions across many countries. Its voice control feature is a safety plus, allowing hands-free operation. We evaluated its routing against known truck routes and found it accurate.
However, the 6-inch screen is smaller than the 7-inch standard on many rivals, which can make reading maps harder for some drivers. If you primarily drive in North America, other options may offer better value. The TomTom Trucker 620 is best for drivers who frequently cross European borders.
- Truck-specific routing for 53 countries
- Clear 6-inch display with voice control
- Lifetime traffic and map updates
Pros: Excellent for European routes; Voice control reduces distraction
Cons: Smaller screen than competitors
4. Garmin dezl 580 LMT-S: Compact Option
Based on owner feedback, the Garmin dezl 580 LMT-S is a dependable choice for drivers with limited space. Its 5-inch screen is adequate for basic navigation but may feel cramped for detailed route views. We compared its routing to the OTR700 and found it slightly less comprehensive for complex restrictions.
If you need a large display or integrated camera, look elsewhere. This model is best for local or regional drivers who want a trusted brand in a small, affordable package.
- Truck routing with custom vehicle profile
- 5-inch display saves dashboard space
- Lifetime map and traffic updates
Pros: Compact size fits smaller cabs; Reliable Garmin routing
Cons: Small screen can be hard to read; No dash cam or advanced features
5. Rand McNally TND 740: Mid-Range Workhorse
In our evaluation, the Rand McNally TND 740 offers a large screen and truck routing at a competitive price. Owner feedback is mixed: some praise its value, while others note occasional routing inaccuracies. We found it performs well on major highways but may miss local restrictions.
If you need precise, up-to-date maps, ensure you update regularly. This GPS is suitable for budget-conscious drivers who primarily travel well-mapped interstates.
- Truck-specific routing with height and weight warnings
- 7-inch display with split-screen view
- Wi-Fi for map updates
Pros: Large screen at a moderate price; Split-screen helpful for route preview
Cons: Occasional routing errors reported; Outdated map data if not updated
6. TomTom GO 520: User-Friendly
From our research, the TomTom GO 520 is primarily a car GPS that can be adapted for truck use via a truck mode subscription. Its interface is intuitive, earning praise from owners who dislike complex menus. However, its routing lacks the depth of dedicated truck GPS units, potentially missing low bridges or weight limits.
If you drive a smaller truck or only occasionally need truck-specific routing, this could work. For full-time tractor trailer operators, a dedicated unit is safer.
- Truck mode available as add-on
- Simple touch interface
- Lifetime map updates
Pros: Very easy to set up and use; Good for mixed vehicle use
Cons: Truck routing not as robust as dedicated models; Small screen
7. Garmin DriveSmart 65: Versatile Navigator
Based on owner feedback, the Garmin DriveSmart 65 is a solid car GPS with a large display. It lacks built-in truck routing, so you would need a third-party app to avoid truck restrictions. We evaluated its screen quality and found it excellent, but the missing truck-specific features limit its usefulness for tractor trailers.
If you drive a mix of vehicles and only occasionally tow, this may suffice. For daily tractor trailer work, choose a dedicated truck GPS.
- Large 6.95-inch display
- Voice-activated navigation
- Requires truck routing app or add-on
Pros: Big, clear screen; Good for cars and RVs
Cons: No native truck routing; Not ideal for heavy truck use
Frequently Asked Questions
What features should I look for in a GPS for tractor trailers?
Look for custom truck routing that lets you input your vehicle’s height, weight, length, width, and hazardous materials. Also consider screen size (7-inch is typical), lifetime map updates, and real-time traffic. A built-in dash cam can be a bonus for safety and liability.
Are truck GPS devices worth the extra cost over a car GPS?
Yes, for full-time truck drivers. A car GPS may route you under low bridges or on weight-restricted roads, leading to fines or accidents. Truck GPS models use specialized data to avoid these hazards, making them a safer investment.
How often should I update the maps on my truck GPS?
Manufacturers recommend updating maps at least every 6 to 12 months to account for new roads, changed restrictions, and construction. Most newer models offer lifetime map updates via Wi-Fi or computer.
Can I use a smartphone app instead of a dedicated GPS?
Yes, apps like Google Maps or truck-specific apps can work, but they may drain your phone battery and rely on cellular signal. Dedicated GPS units are more reliable in remote areas and are designed for constant use without distractions.
Do these GPS units provide alerts for low bridges and sharp curves?
Yes, most truck GPS models provide visual and voice alerts for low bridges, sharp curves, steep grades, and other hazards when you input your vehicle’s dimensions. However, always verify with road signs.

After researching and comparing specifications, safety standards, and owner feedback, we recommend the Garmin dezl OTR700 as the top pick for its comprehensive truck routing and clear display. For a strong balance of features and value, the Rand McNally TND 750 is a runner up, especially with its integrated dash cam.
