The Garmin Dezl OTR500 is a GPS navigator specifically designed for truckers. It boasts features that cater to the unique needs of professional drivers, making it a valuable tool for navigating the open road. Here’s a detailed breakdown of the Dezl OTR500’s strengths and weaknesses to help you decide if it’s the right choice for you.


  • Custom Truck Routing: This is the core function of the Dezl OTR500. It factors in the size and weight of your truck to avoid unsuitable roads with low bridges, tight corners, or weight restrictions. This saves time and frustration by ensuring you stay on safe and legal routes.
  • Load-to-Dock Guidance: This innovative feature goes beyond just getting you to the delivery address. It provides detailed guidance within the destination facility, helping you locate specific loading zones or storage lots, potentially saving valuable time spent maneuvering in unfamiliar locations.
  • Truck-Friendly Resources: The Dezl OTR500 comes preloaded with a directory of truck stops, service stations, and parking areas specifically catering to large vehicles. This eliminates the stress of finding essential amenities on the road.
  • Driver Alerts: The Dezl OTR500 keeps you informed about upcoming road hazards, weight restrictions, and potential delays. It can also integrate with PrePass weigh station bypass systems (requires separate subscription) to streamline your weigh station experience.
  • Easy-to-Use Interface: The Dezl OTR500 features a bright, 5.5-inch touchscreen display with a user-friendly interface. Menus are straightforward, and features are clearly labeled, making it easy to access information while on the road.


  • Limited Display Size: While the 5.5-inch display is adequate, some truckers might prefer a larger screen for better visibility, especially when viewing detailed maps or complex maneuvers.
  • Smartphone App Dependence: To access live traffic, weather updates, and real-time fuel prices, you need to pair the Dezl OTR500 with your smartphone and download the Garmin Drive app. This can be inconvenient if you don’t have a compatible smartphone or prefer a standalone navigation solution.
  • No Built-in Dashcam: While the Dezl OTR500 allows pairing with a backup camera (sold separately), it doesn’t have a built-in dashcam for recording footage. This can be a disadvantage for drivers who want video evidence in case of accidents.


The Garmin Dezl OTR500 is a solid GPS navigation option for truck drivers. Its custom truck routing, load-to-dock guidance, and truck-friendly resources are valuable features that can significantly improve efficiency and route planning. The user-friendly interface makes it easy to operate, and the ability to connect with a smartphone app for additional features adds further value.
