Customized Truck Routing

To help you make the most of its high-resolution, pinch-to-zoom display, dēzl 780 LMT-S comes preloaded with maps that also include truck-related route warnings — such as bridge heights, sharp curves, steep grades and more — for most major roads and highways. Just enter your vehicle profile information (customizable by height, weight, length, width and hazardous materials), and find truck-preferred routes suitable for the size, load and weight of your truck³.

For added convenience, the Simple Truck Profile lets you easily swap trailer sizes with the touch of a button.

Free Live Services

What’s happening on the road ahead? Smartphone Link is a free mobile app that connects your dēzl 780 LMT-S with your iPhone or Android smartphone. When paired, your dēzl can access real-time information² such as traffic and weather information. You may also purchase premium content — such as advanced weather radar data and images from traffic cameras — within the app.

Built-in Wi-Fi Keeps You up to Date

It’s easy to keep your maps and software up to date because the dēzl 780 LMT-S features built-in Wi-Fi. When a new update is available and you’re connected to a Wi-Fi network, you’ll automatically receive an on-screen notification.

Find a Service Facility

If the unexpected happens, the dēzl navigator’s Truck & Trailer Services directory lists more than 30,000 truck repair and service locations in the U.S. and Canada, including those offering after-hours road service. dēzl 780 LMT-S also has an included Service History Log so you can record the dates and type of service performed. Conveniently keep track of tire mileage, tire pressure, oil changes, tire changes and more.

Dispatch and Track

dēzl 780 LMT-S comes preloaded with a simple truck monitoring solution that lets fleet operators easily track drivers and send communications, such as a text message containing a delivery address when paired with a compatible smartphone. Your driver can select the address from within the text message and seamlessly route to the destination.

Add a Backup Camera

See what’s behind your truck as you move in reverse by adding a Garmin backup camera (sold separately). The dēzl 780 LMT-S truck navigator is compatible with the Garmin BC 35 wireless backup camera. When paired, dēzl shows transmitted footage, right on its navigation display.

Navigate with Ease

The navigator includes detailed maps of North America5, millions of Foursquare POIs and new TripAdvisor ratings for restaurants, hotels, and attractions along a route or near a destination. To help you stay focused on the road, dēzl 780 LMT-S comes equipped with powerful speakers that deliver spoken turn-by-turn directions you can hear loud and clear, even over road noise.

An onboard Trip Planner lets you create multiple-stop routes and plan and save future trips. Plus, Easy Route Shaping lets you simply touch the screen to add a point on the map and adjust your route to include preferred roads, cities or locations.

    I like wide screen and fact that it can connect to WiFi.
    However, I cannot trust it's maps I posted a photo. GPS was asking me to turn right and there is sign posted on street right turn not allowed for trucks. I drive a big rig so have to be very careful. I cannot trust its accuracy completely. Would be nice if there was an built-in option to amend or report the map.
