The 9 Best Truck GPS Systems September, 2019 (And 3 Other Models)

Smaller truck GPS (Garmin also offers a 7-inch unit) with a Dashboard mount and a 5-inch display.

The Garmin Dezl 570LMT is designed mainly as a GPS for trucks, although, according to one reviewer, it could also prove to be a reasonable purchase for those who drive smaller vehicles or cannot make space for large 7-inch units. Like most other 5-inch trucker GPS models, this 4-star unit pretty much offers the fundamentals, such as truck routing (obviously for customized routing, depending on the weight and dimensions of your vehicle) as well as a digital log of things like fuel usage and truck maintenance.

Out of the Dezl 570LMT's 720 reviews, the most positive ones include a reviewer commenting on its efficient trucking routes and easy free updates, while others kept their comments short and simple, saying things like it works well and my husband loves it. Another user praised this 5-inch trucker GPS's routing system, calling it a huge time-saver, but also noted that it occasionally gets speed limits wrong, buy hey, what kind of GPS does not have hiccups once in a while, right? No GPS is perfect and worth blindly following after all, as one user puts it.

A few buyers were not as enthusiastic, however, with most of the negative stuff being thrown at this truck GPS unit focusing on its being defective right out of the box -- a recurring occasional complaint with most consumer products, especially that some of these users were talking about a refurbished unit. Some users also cautioned that it has tendencies of taking you on weird routes (GPS should never be taken without a grain of salt) and it sometimes failed to locate even prominent addresses.

At the end of the day, our review crawler algorithm, after weaving its way through a total of 2904 reviews for truck GPS systems, concluded that the Garmin Dezl 570LMT certainly belongs to our list of the top 9 truck GPS units on the market.
