Quick verdict
The Garmin dēzlCam OTR725 is our recommended choice for drivers who want more truck-specific tools. The Garmin dēzlCam OTR710 is a good alternative for drivers who do not need these additional features.
Both devices have a 6.95-inch screen, a built-in dash cam, and the same verified truck navigation functions. They support custom truck routing, satellite arrival imagery, PrePass, and live traffic updates. Both also have the same dimensions, weight, and stated battery life.
The main differences are CAT Scale support, community loading dock information, and release year.
The OTR725 was released in 2024 and includes CAT Scale support and community loading dock information. The OTR710 was released in 2022 and does not include these two features.
For most drivers, the OTR725 offers more truck-specific functions without an increase in device size or weight.
Why choose Garmin dēzlCam OTR710?
Choose the Garmin dēzlCam OTR710 if you want a truck GPS with a built-in dash cam and do not need the additional tools of the OTR725.
The OTR710 has a 6.95-inch screen with a resolution of 1024 × 600 pixels. It measures 6.97 × 4.17 × 1.38 inches and weighs 9.56 oz. These specifications are identical to those of the OTR725.
Its integrated dash cam supports 1080p video recording and automatic incident recording. This lets you use one device for truck navigation and road video recording.
The OTR710 also supports truck-specific routing based on vehicle dimensions and weight. It provides hazmat support, bridge height warnings, weight limit warnings, and steep grade alerts.
Additional features include satellite arrival imagery, truck parking information, PrePass support, and live services through the Garmin dēzl smartphone app.
However, the OTR710 does not include CAT Scale support or community loading dock information. These are two verified advantages of the OTR725.
Both devices have a stated battery life of up to 30 minutes.
Choose the OTR710 if you want the same verified core navigation functions and can buy it at a lower price.
Why choose Garmin dēzlCam OTR725?
Choose the Garmin dēzlCam OTR725 if you want a truck GPS with additional tools for daily truck operations.
The OTR725 was released in 2024, two years after the OTR710. It has the same screen size, resolution, dimensions, weight, and battery life as the older model.
The main advantage is its additional truck-specific information.
The OTR725 includes a CAT Scale locator. This can help you find CAT Scale locations when you need to weigh your truck.
It also provides community loading dock information. This feature can help you identify loading areas and truck entrances before you arrive at an unfamiliar delivery location.
These tools can be useful for drivers who make frequent deliveries or travel to locations they do not know.
Like the OTR710, the OTR725 has a built-in dash cam with incident recording. It also supports truck-specific routing, satellite arrival imagery, PrePass, and connected services.
The newer release year does not confirm better routing accuracy, faster performance, or better video quality. The supplied specifications do not establish these differences.
Choose the OTR725 if CAT Scale locations and community loading dock information are important for your work.

Final recommendation
We recommend the Garmin dēzlCam OTR725 for drivers who want the more complete set of verified truck-specific tools. Its CAT Scale locator and community loading dock information give it a functional advantage over the OTR710.
Choose the Garmin dēzlCam OTR710 if you do not need these additional features. It provides the same verified screen specifications, battery life, truck navigation functions, and connected services. It also has an integrated dash cam.
If the OTR710 costs less, it can be the better value for drivers who only need the shared features. Compare current prices before you buy.
Neither model has a verified advantage in routing accuracy, screen resolution, or battery life.
Both GPS units can calculate routes based on truck dimensions and restrictions. However, map information can be incomplete or out of date. Always follow road signs and check bridge clearances, weight limits, and local restrictions.
