The Garmin dēzl OTR720 is our current best overall dedicated truck GPS for drivers who want a 7-inch in-cab navigator without paying for an integrated camera or committing to a larger screen. Its appeal is practical rather than flashy: it occupies the middle ground between a compact unit that can feel tight and a large display that may be harder to mount well.
Who the OTR720 Fits Best
The OTR720 is a strong starting point for an owner-operator or company driver who wants a dedicated navigation display to remain visible and usable while the phone is handling calls, messages, dispatch, or backup information. A 7-inch screen offers enough map area to make turns, lane context, and stops easier to review without requiring the physical footprint of an 8-inch or 10-inch device.
It is especially sensible when the cab has a stable, legal mounting position for a mid-size display. Before deciding that 7 inches is automatically right, measure the intended location and think through power-cable routing, vents, mirrors, controls, vibration, and forward visibility. A screen is useful only when it can be mounted securely and read without becoming a distraction.
What the Current OTR Platform Is For
Garmin identifies the OTR720 as part number 010-02924-00 in its current dēzl OTR range. The platform is built around truck-oriented trip planning: you enter the relevant vehicle profile and use the navigator to organize a route, review road warnings, plan arrivals, and work with the device’s truck-focused guidance. That is a more natural fit than ordinary car navigation when the vehicle’s dimensions, weight, and operating constraints belong in the planning process.
That description should not be read as a promise that a route is automatically legal, safe, or appropriate. Enter the truck profile accurately, keep maps and device software current, inspect important route segments before departure, and defer to posted restrictions, current road conditions, dispatch instructions, and professional judgment whenever they conflict with a suggested route.
The 7-Inch Advantage Is Placement, Not Just Size
The OTR720 is the practical middle option in the current lineup. Compared with the 6-inch OTR620, it gives more room for map detail and split information without jumping to a much larger panel. Compared with the OTR820, it asks less of the mounting location. Neither tradeoff is universally better: drivers who have a tight windshield or dash may be better served by the smaller unit, while drivers with a stable, open mounting location may value the larger screen enough to choose the OTR820.
Do not choose based on a screen-size number alone. Sit in the normal driving position, identify the exact mounting surface, and make sure the navigator will not obstruct a safe view or other necessary controls. The best display is the one you can place securely and use consistently.
Connected Features Need a Real-World Workflow
Some connected dēzl features rely on Garmin’s compatible phone app. That can be useful when a driver already keeps a phone paired in the cab, but it is not the same as every feature working independently in every situation. Consider whether the phone will normally be available, charged, and connected as part of your workflow. A dedicated navigator can reduce competition for the phone screen, but it does not eliminate the need to understand which services depend on the paired device.
For many drivers, the sensible arrangement is a dedicated navigator for the primary route and a phone for communication or backup information. Treat both tools as part of a route-review process rather than a substitute for it.
When to Choose a Different Current Model
Choose the Garmin dēzl OTR620 if a smaller 6-inch display is the better physical fit. Choose the Garmin dēzlCam OTR725 if an integrated dash cam is a genuine setup priority, not just an extra feature. Choose the OTR820 when more map area is valuable and the cab has a secure place for an 8-inch unit. Drivers who prefer the Rand McNally navigation platform should compare the RANDTAB7 instead of assuming a Garmin is the only serious option.
The important distinction is buyer fit. The OTR720 is our broad recommendation because it solves the most common dedicated-GPS job well; it is not a claim that every driver needs the same screen size or feature mix.
What It Does Not Replace
A truck GPS is planning support. It does not replace pre-trip route review, posted signage, local restriction checks, company policy, traffic awareness, or the driver’s judgment. It also does not decide the right camera setup, phone workflow, or cab mounting position for you. Those practical constraints are why the model choice matters more than a generic checklist.
A Sensible First-Day Setup
Before relying on any navigator for a regular route, install it in the intended position, enter the vehicle profile carefully, and review its proposed route while parked. Confirm that the display remains readable in normal cab lighting and that the mount stays stable over ordinary vibration. Pair the phone only if the connected workflow is one you expect to maintain; an occasional pairing that is never renewed is not the same as a dependable day-to-day tool.
Then use the device on familiar work first. That gives you a chance to understand how it presents warnings, stops, arrival information, and route changes before a difficult or unfamiliar trip. It also makes it easier to spot an incorrect vehicle setting or an awkward mount while there is time to correct it.
Use the Route Screen Before the Road
The best time to question a route is before the truck is moving. Review the broad path, the important turns, restricted areas, fuel or stop plans, and any segment that does not match your knowledge of the run. A dedicated screen can make that review more convenient, but the benefit comes from the review itself. Keep a backup plan when traffic, construction, dispatch changes, or local restrictions make the suggested route unsuitable.
Bottom Line
If you want a current 7-inch dedicated truck navigator and do not need an integrated camera, the OTR720 is the most balanced place to start. Verify the exact listing and included hardware before checkout, then compare it against the full Top 5 Editorial Picks and the Truck GPS Buyer’s Guide if screen size, mounting, or camera requirements are still undecided.
