Garmin dezl OTR720 7ft Truck GPS Navigator - Trucker-Focused Routing

Our review of the Garmin dezl OTR720 finds it aimed squarely at professional drivers who need a clear in-cab display and truck-aware routing. The standout reason to consider the unit is its large 7' high-resolution touchscreen paired with trucking-specific navigation tools like custom truck routing, bridge and curve alerts, and BirdsEye Direct satellite imagery for precise arrival planning. For drivers who use the dezl app, the community-shared parking and loading dock data plus wind speed overlays add practical, real-world context that helps on long hauls.

Key Features

• 7' touchscreen: A bright, crisp high-resolution display makes maps and directions readable at a glance while driving in-cab.
• Custom truck routing: Routes are calculated by the size and weight of the truck to avoid unsuitable roads, helping reduce reroutes and risky passages.
• BirdsEye Direct Satellite Imagery: High-resolution overhead images assist with approach planning to loading docks and security gates.
• Community-shared locations: When paired with the dezl app, drivers can find and rate truck parking, loading docks and entrances used by other truckers.
• Safety overlays and alerts: Bridge height, sharp curve warnings and wind speed overlays increase situational awareness for hazardous conditions.
• PrePass and CAT Scale integration: On-screen PrePass notifications and quick access to nearby CAT Scale sites streamline weigh station and compliance stops.

Who It's For

The dezl OTR720 is best for professional truck drivers and fleet operators who want a dedicated navigator with a large screen and truck-specific decision aids. Drivers who rely on community-shared parking, loading dock data, and satellite approach imagery will get the most value, particularly when paired with the dezl app on a compatible smartphone.

It is less appropriate for casual drivers or fleets that do not use smartphone connectivity features, since several benefits-wind alerts, parking ratings and PrePass notifications-require the dezl app and paired phone. Those who need a basic point-to-point GPS without trucking features should consider a simpler unit.
