Garmin completely changed the mounting system for its large-screen truck GPS units, and if you own a Garmin dezl OTR800, OTR810, OTR820, OTR1000, OTR1010, or OTR1020, you have probably already noticed something does not fit the way older mounts did. This guide explains Garmin dezl OTR mount options and provides a few recommendations beyond the ones included in the box.
That is because these units use a larger 22mm ball system paired with a powered magnetic cradle, instead of the older 17mm system found on smaller GPS devices. The change improves stability, but it also means most traditional GPS mounts will not work.
In this guide we break down the best mounting options for OTR truck setups, including long-reach mounts, permanent AMPS installs, and beanbag friction mounts that hold up in real driving conditions.
| Mount | Best For | Mounting Style |
|---|---|---|
| VAUBORTTI AMPS Drill-Down Mount | Permanent installs, fleet vehicles | AMPS drill-down base, 22mm arm |
| 1Zero Heavy-Duty Suction Mount | Cabs with extra distance to the windshield | Windshield suction, 22mm ball |
| Triplinger Beanbag Friction Mount | Fleets mixing 17mm and 22mm devices | Dashboard, dual 17mm/22mm neck |
| VAUBORTTI Aluminum Beanbag Mount | Uneven or sloped dashboards | Dashboard, 22mm aluminum arm |
Why OTR Mounting Is Different
Truck interiors are different from passenger vehicles in a few important ways: deeper dashboards, more distance to the windshield, higher road vibration, and larger 8 to 10 inch screens. That combination is exactly why Garmin moved to the 22mm system. It provides a stronger connection point and better stability for larger GPS units.
If you are not familiar with how this system works, our guide to 17mm versus 22mm mounts covers the full difference and determines what will and will not fit your device.
What Comes in the Box (And When It Falls Short)
Garmin includes two mounting options with most dezl OTR units: a suction cup windshield mount and a screw-down dash mount, both built for the 22mm ball. These are solid mounts for basic setups, but in a truck cab they often fall short. The windshield may be too far away, the dash angle can limit positioning, and long-term vibration tends to loosen a standard mount over time. If you drive long hours or need a more precise viewing angle, upgrading your mount makes a real difference.
Best Mount Types for Garmin dezl OTR GPS Units
Once you know your dezl OTR unit needs a 22mm mount, the next question is which style fits your cab and driving style best. Below are four options: one permanent AMPS install, one heavy-duty suction mount built for reach, and two beanbag friction mounts.
AMPS Drill-Down Mount (Best Overall Foundation)
If you want a serious, permanent setup, an AMPS-based 22mm mount is where you start. This drill-down mount bolts directly to the dashboard and uses the industry-standard AMPS pattern, which opens the door to a wider ecosystem of brackets and fixed installations. It creates a stable base that will not shift, even in high-vibration environments, which makes it a strong pick for fleet vehicles and drivers who are not moving the mount between trucks.
Heavy-Duty Suction Mount (Best for Reach)
One of the biggest problems in a truck cab is reach. A standard suction mount often leaves the GPS too far away to use comfortably. This heavy-duty suction mount solves that with a reinforced, rubberized double-ribbed aluminum arm and an 8-level ratchet suction adjustment that holds up on rough roads where a basic suction cup starts to creep. A one-pull quick release and dual ball-head design give full rotation and angle adjustment, which helps bring the screen back to a comfortable viewing position.
Dual-Socket Beanbag Mount (Best for Mixed Fleets)
If you would rather avoid drilling into the dash, a beanbag friction mount is a fast, no-tools alternative. This weighted beanbag mount grips flat or slightly curved dash surfaces and includes a dual mounting neck with both 17mm and 22mm sockets, so it works with your dezl OTR unit as well as any older 17mm Garmin device you might also run. That flexibility makes it a good fit for fleets running a mix of GPS models.
Aluminum Beanbag Mount (Best for Uneven Dashboards)
For a sturdier friction option, this mount pairs a weighted, non-slip beanbag base with an aluminum double-socket arm built specifically for 22mm ball devices. It offers full 360-degree rotation, tilt, and height adjustment, which helps on dashboards where a basic beanbag cannot find a stable, level footprint. It is compatible with the dezl OTR800, OTR810, OTR1000, OTR1010, DriveSmart 86, RV 890, RV 895, RV 1090, and RV 1095.
Where to Mount Your Garmin dezl OTR in a Truck
Positioning matters as much as the mount itself. Windshield mounting offers the best visibility but may require a longer arm to bring the device closer. Dashboard mounting is more stable and closer to the driver, but it needs a flat surface to work well. A center console or custom bracket setup is generally the best long-term solution, and this is where AMPS-based mounts perform best.
Common Mistakes to Avoid
- Buying a 17mm mount, which will not fit your OTR cradle at all
- Using an undersized suction mount that fails under sustained truck vibration
- Mounting the GPS too far away, which makes it difficult to use safely
- Choosing a fixed mount with no adjustability once it is installed
Frequently Asked Questions About Garmin dezl OTR Mounts
Do 17mm Garmin mounts fit the dezl OTR series?
No. Every dezl OTR model from the OTR800 through the OTR1020 uses the larger 22mm ball, not the 17mm ball found on smaller Garmin units. A 17mm mount will not connect to the OTR cradle at all.
Will a suction mount hold up to truck vibration?
A basic suction mount can loosen over time on rough roads. A reinforced arm with a multi-level ratchet suction adjustment, like the heavy-duty option above, holds up considerably better than a standard single-lever suction cup.
Is an AMPS mount better than a suction or beanbag mount?
For a dedicated truck that will not change vehicles, yes. An AMPS drill-down mount is the most stable option since it bolts directly to the dash rather than relying on friction or vacuum pressure.
Do these mounts also work with Garmin RV units?
Yes. The beanbag and AMPS mounts covered here are also compatible with the Garmin RV 890, RV 895, RV 1090, and RV 1095, along with the DriveSmart 86, since all of these devices share the same 22mm ball system.
Bottom Line
The dezl OTR series requires a different approach to mounting than older GPS units. The move to a 22mm ball system improves stability, but it limits compatibility with traditional 17mm mounts. The best setup depends on your truck and driving style. The included suction and screw-down mounts work fine for basic setups, a beanbag friction mount is the fastest upgrade if you want to avoid drilling, and an AMPS-based mount offers the most permanent, stable foundation for a dedicated truck.
Once you understand the system and choose the right mount type, you will end up with a setup that is safer, easier to use, and built to handle long hours on the road.
