Quick verdict
Choose the Garmin dēzl OTR720 if you need truck navigation without a built-in dash cam. Choose the Garmin dēzlCam OTR725 if you want truck navigation and video recording in one device.
Both models have a 6.95-inch screen with the same resolution of 1024 × 600 pixels. They also have the same verified truck navigation and connected features. These include custom truck routing, bridge height warnings, satellite arrival imagery, truck parking information, and live traffic updates.
The main difference is the built-in dash cam. The OTR725 has one, but the OTR720 does not. The OTR720 is thinner and lighter. It also has a longer stated battery life.
For most drivers, the choice depends on whether they need an integrated dash cam or prefer a dedicated GPS without a camera.
Why choose Garmin dēzl OTR720?
Choose the Garmin dēzl OTR720 if you want a truck GPS without an integrated camera.
The OTR720 measures 6.97 × 4.17 × 0.75 inches and weighs 8.5 oz. It is thinner and 1.06 oz lighter than the OTR725. Its smaller body can be useful when you have limited space near your windshield or need to move the GPS between trucks.
The OTR720 also has a longer stated battery life. It can operate for up to 1.5 hours on battery power, compared with 30 minutes for the OTR725. This gives you more time to use the device without vehicle power, such as when you plan a route outside your truck.
You get the same verified truck navigation features as the OTR725. These include truck-specific routing, hazmat support, weight limit warnings, and information about truck parking and loading docks.
The main limitation is that the OTR720 cannot record road video by itself. If you need video recording, you must use a separate camera.
Choose the OTR720 if you already have a dash cam or do not need one built into your GPS.
Why choose Garmin dēzlCam OTR725?
Choose the Garmin dēzlCam OTR725 if you want a truck GPS with an integrated dash cam.
The built-in camera can record video of the road during your trips. The OTR725 also supports incident recording and driver-assistance alerts. These functions can be useful if you want to record road events without installing a separate dash cam.
The OTR725 has the same 6.95-inch screen and 1024 × 600 resolution as the OTR720. It also supports the same verified truck routing functions, map updates, and connected services.
However, the integrated camera makes the device thicker and slightly heavier. The OTR725 measures 6.97 × 4.17 × 1.38 inches and weighs 9.56 oz. You must allow enough space for the device and its mount.
Battery life is another difference. The OTR725 has a stated battery life of 30 minutes, compared with 1.5 hours for the OTR720. For normal driving, plan to connect the device to vehicle power.

Final recommendation
We recommend the Garmin dēzl OTR720 for drivers who need a dedicated truck GPS without a built-in camera. It is thinner, lighter, and has a longer stated battery life. It also provides the same verified navigation and connected features as the OTR725.
Choose the Garmin dēzlCam OTR725 if you want an integrated dash cam. It combines truck navigation and video recording in one device. This can reduce the need for a separate camera on your windshield.
Neither model has a verified advantage in truck-specific routing, map updates, or live services. If you do not need the built-in camera, compare the current prices before you buy.
Both GPS units can help you find routes based on your truck dimensions and restrictions. However, road information can be incomplete or out of date. Always follow road signs and check bridge clearances, weight limits, and local restrictions.
