I bought this, but I'm having trouble getting the screen to stay lit for more than 30 minutes. Is there an option for this, or is it a bug?

Answer: I'd say you either have a settings problem or a defect problem. If it's about settings, why don't you start there? Reset all of the settings to default, then test. Also, check the display settings to see if there is a timer on the screen. There are energy-saving solutions, particularly when using a battery. Worst-case scenario: a faulty piece of equipment, in which case I would return it and replace it with another. Carmen does have a great customer service number where you can speak with someone in IT to troubleshoot your problem, which is what I would do first before returning it.

large heavy hauler I have to run particular routes. How many waypoints may I enter to ensure that I can complete a state-mandated route?

Answer: I have discovered no boundaries. I have everything set up in two ways. Set a destination and change the course as waypoints. It will aim to be the shortest or fastest, which may not be acceptable for you. You'll have to experiment with it to find out. Good luck; I am pleased with my OTR 8."

How many languages are spoken here?

Answer: This model comes with around 30 different languages pre-installed.

Does this GPS have real-time traffic updates?

Yes, this model does contain Garmin Live traffic. Pair the DZL OTR800 with your phone and download the Garmin Drive app to enjoy live traffic, weather, and real-time gasoline pricing.

What is the difference between a Garmin OTR and a Garmin LGV?

Answer: There is no distinction; only different model identities exist for different regions.

What's the difference between, for instance, an 800 and an 810?

The 810 is the updated version of the 800. The 810 has a few more features than the 800 but is the same size. On June 9, 2022, Garmin introduced the dzl OTR810 trucking navigator, which is intended to simplify the over-the-road lifestyle for professional truck drivers. Arrival planning with automatic Birdseye satellite imagery to see high-resolution aerial views during truck entrances, security gates, and loading dock destinations is among the new features introduced in the redesigned series. Furthermore, the 8-inch display includes a new split map view that shows previews of the remaining route and imminent weather conditions, as well as the option to mount the devices in landscape or portrait mode to see even more information about the path ahead.

Will this function with a GTM36?

No, the OTR810 receives traffic using the free Dezl App right out of the box. If a user does not wish to utilize the app, they can purchase the optional traffic receiver mount (Powered Magnetic Mount with Video-in Port and HD Traffic Part Number 010-12982-02) and power it with the vehicle's original power line.

Is the load-to-dock guidance on the 810 the same as on the 800?

Yes, the 810 has load-to-dock guidance as well.

Is there a USB port on the mount to charge a Garmin Dashcam 56? I know what the standard 800 does.

The answer is that the 810 does as well.

I drive a flatbed truck and do not require truck routes; is there a setting for cars?

Yes, this model allows for both automobile and truck routing.

Is there a mount included?

Yes, the Garmin Dezl OTR700 comes with a suction cup mount for attaching the GPS to your vehicle's windshield as well as a vehicle power cord that attaches to the vehicle's cigarette lighter or power connection.

How long does a Garmin last?

There are too many variables to consider when predicting a lifespan. I can tell you that we have clients who have been using the same gadget for over ten years. This is greatly dependent on usage and device upkeep. Description: Garmin OTR 800 vs 810
