Garmin vs Rand Mcnally Truck GPS
Compare Garmin and Rand McNally truck GPS units: features, prices, accuracy, and which is best for your rig in 2026.
Choosing between Garmin and Rand McNally truck GPS comes down to your priorities: Garmin offers better routing and a more polished interface, while Rand McNally provides stronger truck-specific data and a lower entry price. Both brands are reliable, but they serve different driver styles. Here is a practical comparison to help you decide.
Why Truck GPS Still Matters
Even with smartphone apps, a dedicated truck GPS is worth it. It routes for your truck’s height, weight, and hazmat restrictions, and it works without cell signal. Garmin and Rand McNally are the two big names, and each has strengths.
Garmin Truck GPS Overview
Garmin’s truck line includes the dēzl series, like the dēzl 785 and dēzl 810. These units are known for:
- Clear, bright screens (7 to 8 inches)
- Reliable routing that avoids low bridges and weight limits
- Built-in dash cam options on some models (like the 785)
- Garmin’s traffic and weather subscription (free for the first year, then $99/year)
- Voice control and Bluetooth for hands-free calling
Price range: $350 to $700 depending on model and features.
Rand McNally Truck GPS Overview
Rand McNally offers the TND series, like the TND 750 and TND 760. They are popular for:
- Strong truck-specific data, including road construction and weight station info
- Easy-to-read maps with clear lane guidance
- Built-in dash cam on the TND 760
- No subscription required for map updates (free for the life of the device)
- A simpler interface that some drivers find less cluttered
Price range: $300 to $600.

Which One Routes Better?
In real-world testing, Garmin tends to route more accurately for truck-specific restrictions. It uses data from the Federal Motor Carrier Safety Administration (FMCSA) and updates its maps frequently. Rand McNally is also good, but some drivers report occasional routing quirks, especially on local roads.
If you run mostly interstates, both work fine. If you run local or regional routes with tight streets, Garmin is the safer bet.
Interface and Ease of Use
Garmin’s interface is more modern and responsive. The touchscreen reacts quickly, and the menus are logical. Rand McNally’s interface feels a bit dated, but it is simpler. Some drivers prefer that, because there is less to fiddle with.
Dash Cam and Extra Features
If you want a dash cam built into your GPS, the Garmin dēzl 785 and Rand McNally TND 760 both have one. The Garmin dash cam integrates with the GPS, so you can review footage on the screen. Rand McNally’s dash cam is similar, but the video quality is slightly lower.
Subscription and Map Update Costs
This is a big difference. Garmin gives you free map updates for one year, then you pay about $99 per year. Rand McNally gives you free map updates for the life of the device. Over five years, that is a $400 difference. If you plan to keep your GPS for a while, Rand McNally saves you money.
Practical Steps to Choose This Week
- List your routes: If you run mostly interstates, either brand works. If you run local roads, lean toward Garmin.
- Set a budget: If you want to stay under $400, Rand McNally TND 750 is your pick. If you can spend $500+, Garmin dēzl 785 offers more polish.
- Decide on a dash cam: Do you want one? That narrows it to the Garmin 785 or Rand McNally 760.
- Check your phone: If you already have a good trucking app, you might not need a GPS at all. But if you want reliability without cell signal, a dedicated unit is worth it.
FAQ
Q: Can I use a regular car GPS for my truck?
A: No. Car GPS does not account for truck height, weight, or hazmat restrictions. You risk low bridges and fines. Always use a truck-specific GPS.
Q: Do these GPS units require a subscription?
A: Garmin requires a subscription for map updates after the first year (about $99/year). Rand McNally includes free lifetime map updates. Traffic and weather features may have separate costs.
Q: Which brand has better customer support?
A: Garmin generally has faster phone support and more online resources. Rand McNally’s support is okay, but some drivers report longer wait times.
Q: Can I mount these on my dashboard?
A: Yes, both come with a suction cup mount. You can also buy RAM mounts for more secure mounting.
The Bottom Line
If you want the best routing and a modern interface, go with Garmin. If you want to save money on map updates and prefer a simpler device, Rand McNally is a solid choice. Both will get you where you need to go, but your budget and route type should decide. Test one out for a week, and you will know which feels right.
