What Makes a GPS Great for Truckers?

A GPS can be the perfect aide to truckers when it comes to traveling off to faraway places. No matter how many times you cover a route, you can still forget the turns and other significant points.

Easy Navigation

Even if you have very clear instructions of the routes you are to take, you can still make mistakes. But, this is something that you do not have to worry about with a properly working GPS.

Why it Stands Out to Us

We have chosen it to be the runner-up due to its Bluetooth technology. It not only helps users connect their smartphones with it but also enables hands-free calling. 

In addition to Bluetooth, there is a built-in microphone for calling. Also, it has a 90-day warranty that lets you use it and check if the product has any faults. So, if there are any issues in the unit, you can get it replaced or repaired promptly. 

Furthermore, there is a free lifetime update of maps and routes, which lets users stay on the best possible routes to their destination.

This GPS unit has left its mark on customers with its smart usage. The six-inch LCD is compact enough to adjust in their vehicle without crowding the front. At the same time, it is adequately sized for them to get maximum information within a few seconds. 

Why it Stands Out to Us

TomTom Trucker has impressed us with this GPS unit as it has an amazing display. The screen has ultra-brightness for better readability in sunlight. 

This makes it easy for truckers to look at and understand the maps without having to squint their eyes to focus. This comes in handy, particularly when you are driving on hot and bright summer days. 

In addition to this, there are 1500+ points of interest already fed into its database. They help you get an idea of the nearby fuel stations, restaurants, and other relevant places.

Bottom Line

Summarizing it, this trucker GPS unit is worth the investment because of its price point. It also has all the features that a trucker might need when it comes to navigation. You also get to enjoy hands-free calling and smartphone messages with it. So, what else is there to ask for?

What Recent Buyers Report

Garmin has earned a reputation on the market with its high-quality products. This GPS unit is no different as it has gained the trust of several users lately. Most of them love its free live traffic updates, which help them change routes and avoid being stuck in traffic. 

Why it Stands Out to Us

The Garmin dezl 580 LMT-S has made it to our list with its customized routing. Drivers can set up its directions according to the weight of the truck. If it is loaded, you can just configure your unit accordingly to avoid any inconvenience. 

Along with this, there is an easy break planning feature in this GPS unit. It helps you get an idea of the places where you can stop and find things that you might need. 

Since it has built-in Wi-Fi, it is easier for you to stay up-to-date with all the changes and modifications of routes. 

Bottom Line

Wrapping up, it is another great option that you can go for. The display quality and accuracy of maps make it more reliable for users. As it has a truck and trailer services directory, you won’t have to worry about anything, even if something goes wrong in your truck.

  • Lane departure warnings included
  • Built-in dash cam to record the drive
  • Magnetic mount helps with installation
  • Customized routing for weight and size
  • Smartphone Link app for smart notifications


  • Pricier than similar models

What Recent Buyers Report

785 LMT-S by Garmin has succeeded in winning the trust of people with its magnetic mount. Users do not need any accessories or complex tools to fix it in its place. This convenience of installation and then the easy-to-use layout makes it a favorite of many.

Why it Stands Out to Us

This trucker GPS unit deserves to be the honorable mention on our list with its latest technology. It has a customized routing for your truck, both in terms of weight and size. 

Other than this, there is a built-in dash cam that records all the activities on your drive. This helps you in making summaries and reports of the drive easily later on. This is particularly helpful for those who are in the shipping business. 

Moreover, there is a Smartphone Link app for this unit, which shows you all the notifications on your phone. 

Bottom Line

Keeping all this in view, this is a great choice for those who do not have a strict budget to stick to. The features like lane departure warnings and built-in Wi-Fi make it an even better option. 

How Does a Trucker GPS Work?

A trucker GPS works much like the GPS on other devices, but there is one major difference. There are sometimes patches on the roads where the usual cellular GPS does not work. This is something that does not happen with trucker GPS. Truck GPS units get a consistent stream of data from satellites. This data displays on the screen in a readable format to help truckers stay on track.

Does GPS Work Without Wi-Fi?

Yes, GPS can work without Wi-Fi, but your GPS unit should have maps already loaded in it. The GPS radio stays in direct connection with the satellites to provide you the required information, even in the absence of Wi-Fi. 

Why Do GPS Trackers Need a SIM Card?

Sim cards are necessary for GPS trackers to form and maintain a connection with the satellites. They help in transmitting both audio and visual data via local transmission channels.

Does GPS Use Cell Towers?

Although GPS works like cell phones as it also uses radio waves, instead of cell towers, the GPS units connect with the satellites orbiting the earth.

What to Look For When Buying a Trucker GPS

Buying a trucker GPS does not take any major head-scratching on your part. You just have to be aware of what you are looking for in order to get the right unit for your truck. This is why we have jotted down the most important things that you should look for in a GPS unit.

Display Size

The first thing that you have to consider is the display size of the trucker GPS unit. This is because it has to have the right dimensions. If you want something compact and practical, then a five-inch display is fine. But, if you want a bigger and clearer display, then go for a seven-inch screen.

Layout Type

The type of layout of the display and software settings is important as well. The layout should be easy to understand and configure. This helps in setting up an interface that suits your needs the best.

Live Traffic

Live traffic and weather updates are significant, too, as they help you stay prepared for the journey ahead. These kinds of heads-up make the journey more comfortable as you already know what to expect. 

Bluetooth Connectivity

You have to be careful of the Bluetooth connectivity of a GPS unit as well. This is to help connect your smartphone with your vehicle for easier use. 

Pros and Cons of GPS for Truckers

A GPS can be a true game-changer for truckers as it helps them in several ways. Here is a brief summary of the pros and cons that a GPS unit has for truck drivers: 


Let’s first have a look at the pros of GPS that truckers enjoy.


Many states have banned the use of smartphones for truck drivers when they are driving. This rules out the possibility of using their cellular GPS for directions. So, getting a trucking GPS can help truckers in this regard.

Truck-Specific Routes

Trucking GPS devices have truck-specific routes. This helps truckers choose the routes that are best for them, according to large vehicle speed limits, weight, and size. 

Fleet Management

Another great benefit of GPS units is that they help fleet managers keep an eye on the whole fleet. You just have to log in all the trucks, and then you can monitor their routes and activities easily. 


Here is what can cause inconvenience for truckers. 

Need Constant Updates

Trucking routes keep getting upgrades based on the height limits and the amount of weight allowed on roads. So, you need to update your GPS unit frequently to keep up with all these changes. 

How Do They Compare?

Next up is a comparison of the most commonly used forms of trucker GPS units. This will certainly help you decide which one you have to settle for.

Trucker GPS vs Regular GPS

Trucker and regular GPS work on the same principle, but they have contrasting features as well. Both use radio waves for the transmission of signals. They both transmit data to and from GPS satellites via these waves. 

A major difference between these two is that trucker GPS units have trucking-specific routes. They consider the size and weight of the trucks and then direct drivers on safe roads. 


Trucker 5″ GPS vs 7″

Truckers go for both five-inch and seven-inch GPS units, based on their preferences. The two have similar basic functioning. They have the same kind of road mapping and navigation tools, which help the drivers stay on the right path. 

However, seven-inch trucker GPS units have a wider display, so they have a clearer layout. They can show more information in one go without cluttering the display.

As the name indicates, a seven-inch GPS unit has a seven-inch wide display. And the five-inch one has a width of five inches. So, the major difference is in the size of these two. 

TomTom vs Garmin

TomTom and Garmin are both widely used by truckers. Both have an accurate mapping system. This is because they have efficient software systems that maintain an unbroken connection with the GPS satellites. 

Garmin has more of a traditional screen with an extra layer over it. But, TomTom has a smart screen that is similar to the screens that smartphones use. This is why TomTom units have a wider display than Garmin ones. 

Garmin vs Rand McNally Truck GPS

Rand Mcnally and Garmin are both popular for their vehicle accessories. Both have realistic and precise road mapping. This helps users get an exact idea of the road conditions and the routes to choose ahead.

Garmin has been around for a longer time than Rand Mcnally, so they have more experience. This has helped them have a better customer care service and an overall better quality of products.



Considering all this, getting a trucker GPS unit can be a great way of improving your driving experience. There are lesser misadventures when you know where you are headed and the right way of reaching your destinations. So, choose a unit that is closest to your needs.
