GMC Sierra 2500HD & 3500HD Device Dash Mounts
Find the Right Dash Mount for Your GMC Sierra HD
GMC Sierra 2500HD and 3500HD trucks combine heavy-duty capability with interiors that may range from practical work-truck configurations to highly equipped professional-grade cabins. They serve contractors, agricultural operations, towing companies, utilities, mobile service businesses and fleets that depend on reliable trucks every day.
Phones, tablets, GPS units and other compatible devices are frequently part of those operations. Drivers may use them for navigation, dispatch, scheduling, electronic work orders, inspections and communication. A vehicle-specific dash mount provides a defined foundation for that equipment without relying on a universal attachment placed wherever space happens to be available.
GMC has changed the Sierra HD center display, controls, vents, trim and console arrangement across different model years. The correct mounting solution therefore begins with the truck’s model year and actual dashboard configuration.
Select your GMC Sierra 2500HD or 3500HD model-year range above to view the available mounts.

Professional-Grade Device Placement for Fleet Vehicles
A fleet may include Sierra 2500HD and 3500HD trucks purchased over many years. The trucks may have different displays, trim levels, center consoles or seating arrangements even when they perform similar jobs.
A-Tach mounts are designed around defined dashboard configurations. This allows a fleet to identify the correct vehicle mount for each interior and establish repeatable equipment combinations for groups of compatible trucks.
A planned vehicle-specific mounting program can help a fleet:
Establish consistent device locations in matching interiors
Select mounts based on verified dashboard configurations
Match holders with company-issued phones or tablets
Accommodate rugged protective cases
Create approved mount-and-holder combinations
Replace holders when devices change
Simplify future expansion and replacement orders
Reduce dependence on assorted universal products
A consistent location can also be useful when employees move between fleet vehicles. Drivers can find company equipment in a familiar area rather than repositioning a personal mount in every truck.
One System with Two Separately Selected Parts
An A-Tach Sierra HD mounting system consists of two separately purchased components:
A vehicle-specific dash mount
A phone, tablet or device holder
The mount and holder are selected independently because they address different requirements.
Part 1: Vehicle-Specific Sierra HD Dash Mount
The vehicle mount provides the foundation for the installation. Choose it according to:
GMC Sierra 2500HD or 3500HD application
Model year
Center-display or radio configuration
Vent and control layout
Dashboard trim
Console or seating configuration, when applicable
Preferred mounting position
Intended device type and size
The product photos and compatibility notes should be compared with the actual truck before a mount is ordered.
Part 2: Phone, Tablet or Device Holder
The holder attaches to the A-Tach vehicle mount and secures the equipment. Choose it according to:
Device dimensions
Protective-case width and thickness
Clamp-style or magnetic preference
MagSafe compatibility
Qi or Qi2 wireless charging requirements
Phone, tablet or specialty-device use
Shared-vehicle or assigned-driver operation
The Sierra’s dashboard determines the vehicle mount. The device, case and operational requirements determine the holder.
This two-part design can add long-term fleet value. If company devices or protective cases change, the fleet may be able to retain its compatible vehicle mounts and replace only the holders.
Phone, Charging and Tablet Holder Options
Depending on the Sierra HD mount and holder selected, an A-Tach system can be configured with:
Adjustable clamp-style phone holders
Holders for large phones and rugged cases
Magnetic phone holders
MagSafe-compatible holders
Qi wireless charging holders
Qi2 magnetic wireless charging holders
Tablet holders
GPS and other compatible device holders
Dual-device installations on select mounts
Measure every device while it is inside the protective case normally used in the field. The case dimensions are more important than the phone brand when determining whether an adjustable holder will fit.
For a tablet or heavier device, confirm that the individual vehicle mount and mounting location are appropriate for the device’s size and weight.
Designed for Trucks That Function as Mobile Workspaces
The cab of a Sierra HD often serves as a workspace between jobs. A properly selected mounting system can support compatible equipment used for:
Navigation and route planning
Dispatch communication
Electronic work orders
Inspection and service forms
Job scheduling
Timekeeping applications
Fleet-management tools
Delivery documentation
Customer information
Jobsite photos
Hands-free communication
These needs are common in:
Construction and contracting
Agriculture and ranching
Towing and roadside assistance
Utility and telecommunications work
Mobile repair and field service
Landscaping and property maintenance
Snow removal
Delivery and route operations
Commercial hauling
Municipal and public-works fleets
Always position mounted equipment so it does not obstruct the driver’s view, cover necessary controls or interfere with safe vehicle operation.
Why the Exact Dashboard Matters
The year and model identify the general category, but the actual dashboard confirms fitment. GMC may use different displays, radios, trim and console arrangements within the same model-year range.
Before ordering, compare:
Center-display size and orientation
Radio or infotainment configuration
Vent shape and position
Climate-control layout
Surrounding dashboard trim
Center console or front seating arrangement
Panel seams used by the mount
Intended device location
Gas or diesel engine selection does not normally determine dash-mount fitment. Compatibility is based primarily on the model year and interior shown on the individual product page.
GMC Sierra and Chevrolet Silverado Compatibility
GMC Sierra HD and Chevrolet Silverado HD trucks may share certain dashboard designs within corresponding model years. However, a Silverado mount should not automatically be assumed to fit a Sierra—or the reverse.
Interior equipment, displays and trim can vary. Use a mount only when the individual product listing specifically includes your GMC Sierra model year and dashboard configuration.
This is particularly important for fleet operators managing both GMC and Chevrolet trucks. Record compatibility using the product part number and verified dashboard style rather than relying only on the exterior model name.
No-Drill GMC Sierra HD Dash Mounts
A-Tach vehicle-specific mounts are designed to install without drilling holes into the Sierra dashboard. Depending on the product, the mount may use compatible panel seams, dashboard edges or other existing interior features.
Always read the supplied installation instructions and insert. Install and test the vehicle mount by itself before attaching the separately purchased phone, tablet or device holder.
A-Tach vehicle mounts avoid relying on many common universal mounting methods, including:
Windshield suction cups
Permanent dashboard adhesive
Ordinary vent-louver clips
Weighted dashboard pads
Cup-holder mounting bases
The result is a dedicated mounting foundation designed around a compatible Sierra HD interior.
Planning a Sierra HD Fleet Installation
Before purchasing mounts for several vehicles, create an inventory that includes:
Fleet or asset number
Sierra 2500HD or 3500HD model
Model year
Trim level
Center-display or radio configuration
Dashboard and vent layout
Console or seating arrangement
Device type and protective case
Required holder features
Selected mount and holder part numbers
Clear dashboard photos are helpful when the fleet contains different model years or equipment packages.
For a large installation, consider evaluating one complete mount-and-holder combination in a representative truck before ordering quantities for all matching vehicles.

Record the A-Tach vehicle mount and holder part numbers assigned to each dashboard and device configuration.
Frequently Asked Questions
Do the Sierra 2500HD and 3500HD use the same dash mounts?
They may share compatible interiors within certain model years, but fitment must be confirmed on the individual product page. Display, trim and console differences can affect compatibility.
Are Sierra HD and Silverado HD dash mounts interchangeable?
Some corresponding GMC Sierra and Chevrolet Silverado HD trucks share dashboard layouts, but interchangeability should never be assumed. Use the mount only when the product listing includes your vehicle and its dashboard configuration.
Will every Sierra mount fit every trim level?
No. Work Truck, SLE, SLT, AT4, Denali and other configurations may have different displays or surrounding trim. Compare the actual interior with the product photos.
Is the phone, tablet or device holder included?
No. The vehicle-specific dash mount and holder are selected and purchased separately.
Why is the two-part design useful for a fleet?
It separates vehicle compatibility from device compatibility. The correct mount is selected for each dashboard, while holders are chosen around company-issued phones, tablets and cases.
Can the vehicle mount remain when our company changes phones?
In many cases, yes. If the mount remains compatible with the truck, the fleet may be able to replace only the device holder.
Does an A-Tach Sierra mount require dashboard drilling?
A-Tach vehicle-specific mounts are designed for no-drill installation. Mounting methods vary, so read the instructions and test-fit the mount before attaching the holder.
Will a holder fit a phone in a rugged case?
Choose the holder according to the phone’s complete dimensions while it is inside its case. Measure the device in its normal working configuration.
Can a Sierra HD mount support a tablet?
Certain mounts may support a tablet when paired with an appropriate tablet holder. Check the individual product page for device-size, weight and mounting-location requirements.
Are MagSafe and wireless charging holders available?
Yes. Magnetic, MagSafe-compatible, Qi wireless charging and Qi2 magnetic wireless charging holders are available separately.
Can two devices be mounted in one truck?
Select vehicle mounts may accommodate two separately purchased holders or another dual-device arrangement. Review the individual mount page for compatibility.
Should we test a mount before placing a large fleet order?
Testing one complete system in a representative vehicle can help confirm dashboard fitment, device position and holder compatibility before wider deployment.
Can A-Tach help with a bulk order?
A-Tach offers bulk purchasing options. Gather the number of trucks, model years, dashboard configurations, devices and holder requirements before contacting A-Tach Mounts.
What should we provide when requesting fitment assistance?
Provide the GMC model, model year, trim, center-display configuration, quantity, intended device and protective-case dimensions. Clear dashboard photos are also helpful.
Equip Your GMC Sierra HD Trucks
Select the correct Sierra 2500HD or 3500HD model-year range, compare each truck’s dashboard with the product photos and choose the vehicle-specific mount developed for that interior. Then add the separately purchased phone, tablet or device holder that meets your operational needs.
For a mixed fleet containing several model years, trims or dashboard configurations, contact A-Tach Mounts before placing a large order. A vehicle inventory, device specifications and clear interior photos can help identify the correct mounting combinations.
