Product Overview
I recently had the pleasure of testing the Garmin Dezl OTR500, a truck routing GPS unit specifically designed for commercial truckers. I ve used many GPS units in my professional driving career, but this one is by far the most impressive. From its easy to read 5.5 inch touchscreen display to its custom truck routing capabilities, this device has it all.
The built in PrePass notifications are a great feature that helps drivers save time and improve efficiency with onscreen notifications of upcoming weigh stations and bypass decisions. The d zl navigator also offers custom truck routing based on the size and weight of your vehicle, along with alerts for upcoming bridge heights, sharp curves, and more.
The Garmin Dezl OTR500 also includes a Truck Trailer Services directory which allows you to filter truck stops by brand or amenities. This is particularly useful if you re looking for a certain type of stop while on the road. Additionally, the unit features industry best load to dock guidance which shows potential loading zones or storage lots when approaching your destination.

One of my favorite features of the Garmin Dezl OTR500 is its voice assistant capabilities that allow you to talk to the device while keeping your hands on the wheel. This is incredibly helpful for drivers who don t have time to take their eyes off the road while navigating through unfamiliar territory. The d zl navigator also works with Garmin eLog compliant ELDs sold separately for subscription free Hours of Service recording, which requires a mobile device to complete the solution.
Overall, I was really impressed with the Garmin Dezl OTR500 and would highly recommend this product to any professional truck driver looking for a reliable and easy to use GPS unit for their vehicle. The device offers a wide range of features that make it perfect for long haul trips and keeps drivers safe by providing accurate route information and helpful alerts about upcoming obstacles or hazards.
