In 1999, Benefon (now called Twig Com) released the first commercially-available GPS, in the form of a safety phone (the Benefon Esc). It was a huge step forward from 1957 when U.S. scientists made note of Sputnik’s position by measuring the frequency of its radio signals and gave them the first, basic idea of the Global Positioning System. Since the Benefon Esc (originally a predominantly European product), we’ve seen the technology improve greatly, as has its popularity.
Garmin Truck GPS
Today, the sheer number of GPS manufacturers and their available models can make for an overwhelming choice. But if there’s one company that stands above the rest, then Garmin would be that company. With a 7-inch glass display, enhanced speakers, and the Spoken Garmin Directions feature, as a truck driver, you’re able to see, hear, and navigate so much better than ever before thanks to the Garmin dezl 770LMTHD.
What We Like: Quality Navigation, Routing, and Customization
The Garmin dezl 770LMTHD 7-inch GPS Navigator is a trucker’s best friend on the road. Designed with truckers in mind, Garmin has included important truck-related information on all of their maps.
This includes sharp curves, bridge heights, and weight restrictions, plus more. All you need to do is add your vehicle’s height, weight, length, and width – you can even specify whether you have hazardous materials. The dezl 770LMTHD takes it from there, planning a truck-friendly route suitable for your profile.
North American Maps
Detailed North American maps are included, and you can download updated versions for as long as your Garmin is operational, absolutely free of charge.
PhotoReal Junction
PhotoReal Junction shows you what your exit lane looks like in real life, so you never miss it, and Active Lane Guidance helps you stay on route with both visual and audio prompts. Stay up to date with the upcoming road conditions, including truck specific speed restrictions, high wind areas, and steep grades.
Trip Planner
Trip Planner helps you select multiple stops when planning your route in advance, or adjusting it on the road. If there’s a road or particular cities that you prefer (or want to include), interact with the 7-inch touchscreen display and let Easy Route Shaping change the prescribed route. To help you plan each day’s ride, the dezl 770LMTHD will keep you posted on sunrise and sunset times.
Garmin Traffic offers free traffic avoidance, so you can be sure you’re always following the fastest route available. The dezl 770LMTHD will also provide you with state and country border notifications, automatically updated according to time zone changes, and even give you an estimate of your arrival time.
Additional Features
Point of Interest
Chances are, you’re not always going to be following a familiar route. When on a new stretch of road, you still want to select relevant POI as your stops, the dezl 770LMTHD identifies truck stops, lodging, parking, and weigh stations relevant to you. You can even filter the suggested stops according to your preferred amenities, such as truck washing services and showers. Many trucking companies have a preferred brand name for parts, which is why Garmin allows you to filter your stops accordingly.
Truck & Trailer Services Directory
Garmin has also included their Truck and Trailer Services directory. This feature is designed to help truckers get any problems sorted out ASAP when things go wrong on the road, by listing more than 30,000 truck repair and service provider in the US and Canada. They’ve taken special care to include after-hours road service providers, knowing that many truckers drive long hours. If something goes wrong in the middle of the night, you don’t want to wait for business hours before getting it seen to, after all.
Service History Log
To help you keep track of every detail of your service record, the dezl 770LMTHD also provides a Service History Log. Record service stops, the type of service provided, tire changes, tire pressure and mileage, oil changes, and more. And to help you keep your hands on the wheel while on the road, you can also use voice commands to interact with your dezl 770LMTHD.
Modes and Connectivity
If you have to switch between loads on different trips, don’t worry: the dezl 770LMTHD features Garmin’s Simple Profile feature. This function gives you the freedom to switch between trailer sizes, all with the simple touch of a button. While the dezl 770LMTHD is designed with truckers in mind, the Simple Profile feature also allows you to switch to car mode at any time, making it a viable model for truckers with a personal car.
You can also link your Garmin with your Android or iOS smartphone using the free Smartphone Link app, allowing you to connect to your mobile data. In this way, the dezl 770LMTHD is able to connect to Garmin Live Services for premium content, such as live weather updates and traffic camera images. For making and taking calls safely on the road, you can also connect via Bluetooth.
Customer Rating
With over 400 customer reviews on Amazon, this GPS is averaging almost a 4 out of 5 stars. Some comments that caught our attention:
For truckers this GPS is worth its weight in GOLD! Simply plug your tractor trailer’s dimensions, plug in your address and away you go. I have more than 17,000 miles logged since June ’17 with this GPS and have never been put in a situation where my vehicle height was an issue.
Pay no attention to bad reviews on this gps. This thing is dead on accurate. Crystal clear screen. Only negative thing I’ve found is not enough low bridge warning. I haul oversized loads. So to test it out I set vehicle height at 14’8″…. I knew there was a 14’6″ overpass on my route. Gps flashed low bridge warning about 2 miles ahead. But problem is by then I’d already passed the last exit before low bridge. So had I really been 14’8″ tall I’d have been S..T out of luck… but other than that it’s best gps I’ve owned period….
Do you have this GPS? Let us know what your experience is like in the comments.
Garmin….waste of money! From not being able to find an address, being two blocks off with an address. To running you into subdivisions. Telling you too late to turn. Having to factory reboot due to a black screen.
I shut down once for a 10 hr layover. Had only 20 miles to my delivery. When I started the next shift, Garmin told told me I had 50 miles to go. What?
My last trip, it took me off a hwy onto a toll road only to put me back on the hwy. Toll road cost me $18 for no reason.
Garmin…… total waste!!!!!
The garming is not 770 truck satnav is ok as long as you don’t go into london because it doesn’t recognise a lot of the postcodes and addresses in london. So I brought the new2020 map update total waste of money.
The outher day I was going down a road where I had to make a right turn GPS did not warn me until I made the turn low bridge up ahead now I had to call the police to back me out I had the GPS on it did not warn what happen
I’ve had the 770 Garmin for 4 years now, I’d give it a 5 star rating even though it’s not 100% accurate. In big cities like on a LA freeway interchange it will, on occasion, change course at the last moment, very frustrating but overall, it’s a beauty, it’s gets me out of anywhere onto the major road in any town.
The heavy traffic detecting is very accurate too. Gets me around any major back up where there are alternate routes. Another awesome feature is the ability to mark your current spot by just touching the truck icon on the screen and saves that location.
Or any other spot on the screen. The voice command feature is useless, but I don’t care about that. This unit will get you in and out of a place with extreme accuracy. Love it
Although many features are nice, I don’t like it, not as user friendly as the Rand McNally. Many of the warnings are not audio able, such as speed limit change, curves. I like to hear the spoken voice , not just a ding.
where is the map option for shorter route on otr1000 ????? have only faster and avoidence option not a short route option.
Very nice piece of equipment, does anyone know where I can get the original power cords?
Garmin factory outlet store has it and other stuff for it.
The windshield mount when it stops sticking to the windshield for any length of time.
Garmin dezl 770 a big bullshit like dezl 760 astre 2 years broke down. Lot of money piece of shit . Now I have to buy another one. Strategically warranties just for 1 year in truck stop and after this if you are lucky can use it for one more year or less.
I also have the Truckers garmen dezel it’s def with the $$ investment
I had It about a year now
I returned the dezl 780 after only 5 days. Sure it’s got a pretty picture but search for an address or business and it’s instant stupidity. I use the good old Rand Mcnally map, Google maps, and the FREE!! MILEON App from PC Miler. And I get along just fine. Too much reliance on electronics makes the brain dumb. I look around and see the proof every day. So you can take that $500-800 POS and use it for a wheel chock.
Sometimes it’s just plain operator error.
Best GPS I’ve ever used and I’ve been an OTR driver for 35 year’s.
Good job Garmin
You just never owned a GPS.
It’s obvious. What do you mean instant stupidity looking for an address, that’s where the 770 shines.
I have the Garmin 770LTMT, it’s a great GPS for us truck drivers, I’m OTR in all 48 states and we also run many of the Canada Provinces. It has many features and I also have two of the premium services for live Weather Radar and Highway DOT Cameras, it’s great you can live weather you are coming into and it’s very accurate and the live cams is really nice for seeing live road conditions and the DOT cameras have video it will also give you the option to see that also right on the Garmin 770 GPS. To get the best out if this GPS is to utilize all of its features, great and very flexible for me as a over the road driver, also works great in Canada. Keep it updated free of charge and you’ll have the latest features and maps. Garmin has done a great job on this. I’m a gadget person and have owned a few truck GPS units over the years, and IMO this is a great gps, no gps is perfect but this comes very close to it.
McNally GPS Gives you the option to ride through narrow streets or continue to your destination as far as you can on the highway does the Garmin GPS give you that option
Under all circumstances I will give 5+ star to Rand Mcnally any day! Rand Mcnally GPS are 100% truck compliant unlike Garmin GPS which most often will route you to truck prohibited roads. And I have tried 2 so called Garmin truck GPS including the most recent Dezl otr 1000.
Sounds like an option I can do without. The Garmin 770 is smarter than that. It Just takes you through the best route without all that distraction, period.
