What Reviewers Are Saying

Reviewers love the Garmin dēzlCam’s services like Apple and Google Maps, which are certainly not found on most standalone GPS cameras and navigators. The most noticeable advantages of this unit are the built-in camera, the seven-inch touchscreen, as well as a navigation system that is voice-controlled. Typically, just a dash camera will cost several hundred dollars, so it’s a good value to be able to buy a dash camera that also comes with built-in GPS along with a large touchscreen.

While Garmin doesn’t list information on their website regarding video quality, you do get an overlay option that can be added to footage taken as well as a large screen that makes playback easier. You can also detach the unit from its mount, so taking pictures of an accident is pretty easy, plus the camera offers features only found in new cars like lane-departure and forward-collision warnings.

The Garmin also includes a Smartphone link allowing you to upload videos and share them through the app as well as give you real-time traffic and weather updates. Bluetooth connectivity lets you make hands-free calling while the built-in WiFi connection provides automatic updates and any smartphone notifications will appear on the unit’s screen.

The GPS offers hotel and restaurant TripAdvisor ratings along with turning directions for each location. You can also purchase a backup camera separately that will connect with the dēzlCam allowing you to see footage that was taken on the back up camera on the touchscreen.

What We Liked

The Garmin is designed to be used by professional truckers. Although an average person can use it, it has tons of features that really only benefit a truck driver. For instance, GPS features include truck routing that can optimize a truck driver’s route based on the vehicle he is driving. Once a truck’s storage details and size are entered, the Garmin will show all the relevant route warnings needed like steep grades, bridge heights, and sharp curves for most of the major United States roads.

For anyone that has several trailers, this unit has a profile system that allows you to save the size of several trucks for convenience. While this GPS and camera are typically used by truckers, it does have a standard car mode that can be used by a regular car. Other features include notifications of points of interest like shower areas, rest stops, fuel, and food as well as parking areas for any of these stops.

With the service facility locator feature, you can access a built-in directory filled with service stations in Canada and the United States, plus it allows you to log in when your truck has undergone maintenance or when it has had a tire or oil change. Plus, fleet operators can appreciate the capability of tracking where their drive is and send addresses through texts.

Like any camera, the Garmin dēzlCam has its pros and cons. This convenient unit also offers live traffic updates, TripAdvisor reviews, built-in Bluetooth and WiFi connections, as well as features that are trucker-friendly like hour logging and fleet tracking. A fully functioning dash camera is also a handy feature while the GPS device provides you with reviews for all the places you are passing by as you travel. This is a sturdy camera that works well if you are in a larger vehicle that travels on bumpy roads occasionally.

What We Didn’t Like

Customer complaints have consisted of the camera’s size and its equipment. There is a five-inch model that is better suited for a small vehicle while the seven-inch model was really designed for a truck. Plus, unlike other cameras that operate by moving on a ball joint, the whole camera needs to be moved to change its angle. This isn’t a big deal in a truck, which it was designed for, but drivers of smaller vehicles have had an issue with this.

Also, the mount for the camera is shorter than other GPS units on the market. And the included suction cups have been found to be too small and fall easily off the windshield.

Some truckers have had issues with the mapping features and have had a hard time finding parking and fuel stops. The GPS has also been reported to take drivers to weird roads that are way out of their route, some roads are just not in the GPS at all, making finding delivery locations difficult, and it also sometimes doesn’t show the speed limits of certain roads. It is also hard to customize the map page, and it includes annoying icons that you cannot move.

Others have complained that the Android interface system is slow with the Garmin, particularly when used at the same time as the camera. The camera itself offers lower quality footage, which could be due to the extra functions that the camera offers. You also need to be careful with where you place the camera so that the videos aren’t usable.

Other complaints include a slow download speed, frequent reboots, lack of information on weighing stations, and lack of SD cards. Also, the camera can sometimes interfere with the line of sight of the driver.


When considering the unit overall, the benefits of this device outweigh its issues. Primarily a GPS device, this unit includes a camera with many features that offers great flexibility and good image quality. It has similar ratings with other GPS devices and is capable of updating date locations automatically. The Garmin dēzlCam also includes unique trucking features that appeal to many truckers on the road.

After spending years on the road, I had a lot of time to think about the hardships that came with the trucking industry. I realized there was an opportunity to lend a hand a create a resource for truckers by truckers. With the help of my tech-savvy son, I built Trucker Geek as a way to show people that becoming a driver doesn’t need to be a stressful headache.
