Garmin dezl OTR720 (Renewed) Review: Truck-Focused Navigation with Modern Connected Features

Garmin dezl OTR720 (Renewed) Review: Truck-Focused Navigation with Modern Connected Features

Overview

The Garmin dezl OTR720 (Renewed) is a large 7-inch GPS navigator built specifically for commercial trucking. It combines Garmin’s truck-specific routing engine with a bright, high-resolution touchscreen, offering features such as custom truck profiles, detailed junction guidance, satellite imagery, and live data on wind conditions and parking availability when connected to a smartphone.

The renewed version aims to provide the same functionality as a new unit at a lower cost, while having been inspected and restored to a fully functional state. For professional drivers who prefer a dedicated navigation device over relying solely on smartphone apps, the dezl OTR720 remains one of Garmin’s more capable mid-size truck-centric models.

Note: Pricing on Amazon for this renewed unit can fluctuate; always check the current price (for example, $339.99 at the time of viewing) before deciding.

Key Highlights

  • 7-inch capacitive touchscreen that is large enough to see at a glance without taking too much dash space.
  • Custom truck routing based on vehicle dimensions, weight, hazardous materials, and axle configuration to help avoid restricted roads and low clearances.
  • High-resolution satellite imagery to preview yards, tight access points, and loading dock approaches.
  • Wind speed and weather overlay when paired with a smartphone, giving drivers advance notice of potentially hazardous crosswinds.
  • Community-shared loading docks and parking availability, supplementing Garmin’s own POI and parking database.
  • Renewed/refurbished condition, typically cleaned, tested, and reset, offering potential savings over a brand-new unit.

Core Features

1. Display and Hardware

  • 7-inch edge-to-edge touchscreen with good brightness for daytime cab use and adjustable night mode.
  • Mounting hardware and a 12V power cable are usually included; confirm the package contents on the product page.
  • Internal storage with support for microSD cards (commonly up to 256 GB) for additional maps and data.

2. Custom Truck Routing

  • Ability to create detailed truck profiles specifying:
    • Vehicle height, width, and length
    • Gross vehicle weight and axle count
    • Hazardous materials where supported
  • Uses that profile to suggest routes that are more appropriate for commercial vehicles, aiming to avoid:
    • Low clearances and weight-restricted bridges
    • Roads not suitable for large commercial trucks
    • Tight residential streets where possible

While no truck GPS can guarantee 100% perfect routing in every region, the dezl OTR720 is designed to reduce the risk of being directed onto unsuitable roads compared to generic consumer navigation.

3. Mapping, Traffic, and Updates

  • Preloaded maps for North America (per typical OTR720 configurations), including truck-relevant points of interest such as truck stops, weigh stations, and service locations.
  • Support for map and software updates via computer or Wi‑Fi.
  • When paired with a smartphone and Garmin’s companion app, it can provide live traffic, helping avoid congestion where truck-appropriate alternatives exist.

4. Satellite Imagery and Yard Detail

  • Integration of bird’s-eye satellite imagery for certain locations, useful for:
    • Identifying truck-friendly driveways and entrances
    • Planning how to approach complicated distribution centers
    • Visualizing backing paths into docks before arrival

This can reduce stress in unfamiliar facilities by letting you preview the layout instead of relying solely on line maps.

5. Wind Speed and Weather Information

  • When connected to a smartphone, the device can display wind speed information along the route, with alerts when high winds are detected or forecast in your path.
  • This is especially relevant for:
    • High-profile trailers
    • Empty or lightly loaded vans where crosswinds are a greater concern

It is best treated as a supplement to DOT advisories and 511 resources, not a replacement.

6. Community-Shared Loading Docks and Parking

  • Drivers can contribute and share information on:
    • Loading dock locations and approaches
    • Parking availability at truck stops, rest areas, and other facilities
  • The device aggregates these contributions to give:
    • Approximate parking occupancy estimates where supported
    • Extra POIs that may not exist in the base database

These features add value, but user reports suggest they are sometimes inconsistent or overly optimistic, so they should be considered advisory.

Usage Experience

Setup and Interface

  • Initial setup typically involves:
    1. Mounting the unit where it has clear line-of-sight and minimal glare.
    2. Creating or selecting a truck profile that matches your tractor-trailer.
    3. Pairing with a smartphone to enable live services and syncing saved locations.
  • The interface follows Garmin’s modern dezl layout:
    • Large on-screen buttons for common actions
    • Clear lane guidance graphics
    • Simple menu hierarchy once you become familiar with it

On-the-Road Behavior

  • Routing is generally conservative, prioritizing safer truck routes over the absolute fastest path.
  • Turn and lane prompts are usually given with adequate lead time, and the 7-inch screen makes junction diagrams easy to read.
  • As with most truck GPS units, there can be instances where:
    • The suggested route is longer than necessary but safer for heavy vehicles.
    • Occasional misclassification of a road’s suitability requires driver judgment.

Connected Features

  • Pairing with a smartphone through Garmin’s app unlocks:
    • Live traffic and incident alerts
    • Weather overlays and wind information
    • Sync of saved places between the device and app
  • Many drivers find it helpful to plan a stop in Google Maps (for example, dropping a pin at a specific gate) and then send that location to the dezl device via the app, combining consumer-map flexibility with truck-aware routing.

Renewed vs. New

  • As a renewed unit, the OTR720 you receive has typically undergone:
    • Functional testing
    • Cleaning and data wipe
    • Replacement of obviously worn accessories where applicable
  • The main trade-offs compared with a brand-new device are:
    • Possible minor cosmetic wear
    • Dependence on the seller’s testing standards
    • Potentially shorter or different warranty terms compared with buying new from Garmin

Strengths

  • Truck-tailored routing reduces exposure to unsuitable roads compared to consumer GPS solutions.
  • Large, bright 7-inch display is easy to read from typical mounting positions.
  • Satellite imagery and yard detail help with complex last-mile navigation into distribution centers and tight lots.
  • Wind speed and weather alerts add situational awareness for high-profile vehicles.
  • Community-based loading docks and parking data can reveal options beyond standard databases.
  • Renewed unit pricing (for example, $339.99 on the product page) can make it more affordable than buying new.

Weaknesses

  • Like all truck GPS units, it is not infallible; it can occasionally:
    • Suggest suboptimal routes
    • Misjudge parking or access points
  • Community-sourced parking and dock information may be incomplete or inaccurate in some areas.
  • Requires smartphone connectivity to unlock its full potential (traffic, weather, online search, syncing).
  • Being a renewed product, long-term reliability may vary based on previous usage and refurbishing quality.
  • Dedicated hardware means one more device to manage, update, and power in the cab, especially if you already use navigation apps on a phone or tablet.

Suitable Scenarios

The Garmin dezl OTR720 (Renewed) is particularly well-suited for:

  • Over-the-road and regional truck drivers who want a dedicated navigation screen separate from their phone.
  • Newer drivers who appreciate conservative routing and clear lane guidance during their first years on the road.
  • Drivers who frequent large distribution centers or ports, where satellite imagery and dock details can simplify last-mile navigation.
  • Operators in windy regions who value built-in wind alerts as an extra layer of situational awareness.
  • Cost-conscious buyers who prefer Garmin’s dezl platform but are looking for savings versus buying a brand-new unit.

It may be less ideal for:

  • Drivers who prefer to consolidate everything on a smartphone and are comfortable using advanced trucking apps exclusively.
  • Users who require absolute cutting-edge hardware and prefer the latest model in the dezl lineup with the longest possible support window.

Final Evaluation

The Garmin dezl OTR720 (Renewed) delivers a mature, truck-focused navigation experience that remains competitive for professional drivers. Its strengths lie in detailed truck routing, a clear 7-inch display, and value-added features such as satellite imagery, community-sourced dock and parking information, and wind alerts when connected to a smartphone.

As with any dedicated trucking GPS, it should be treated as a professional aid rather than an unquestionable authority. Cross-checking its guidance with road signs, an atlas, or satellite imagery from other sources remains essential. The renewed status introduces an element of variability in cosmetic condition and long-term durability, but it also enables a lower entry cost (e.g., $339.99 on the Amazon listing), making this unit attractive to drivers who want a capable Garmin dezl navigator without paying full new-device pricing.

Overall, for drivers who prefer a dedicated screen and Garmin’s established truck-routing ecosystem, the dezl OTR720 (Renewed) is a solid, practical choice that balances functionality, visibility, and cost.
