GMC Terrain Phone & Device Dash Mounts

Find the Right Dash Mount for Your GMC Terrain

A-Tach GMC Terrain dash mounts provide a dedicated mounting location for your phone without relying on a windshield suction cup, cup-holder base or ordinary vent-louver clip. Each mount is developed around a compatible Terrain dashboard, display and mounting location.

GMC has redesigned the Terrain interior more than once since the model was introduced. Some model-year ranges were also offered with different infotainment display styles. Selecting the correct mount therefore requires checking both the model year and the actual dashboard shown in the product photographs.

Choose Your GMC Terrain Model Year

2025–Current GMC Terrain Dash Mount

This vehicle-specific mount is designed for the completely redesigned dashboard introduced with the 2025 GMC Terrain.

The mount fits in the dashboard locations shown in the product photographs. Review every image to compare the available position, surrounding trim, display, vents and controls with your vehicle.

Because the 2025 interior is substantially different from the previous generation, mounts made for the 2018–2024 Terrain should not be expected to fit the 2025–current dashboard.

2018–2024 GMC Terrain Dash Mounts

GMC offered more than one infotainment display style during this model-year range. Two vehicle-specific mount options are available:

• A-Tach #50247: Only for the smaller infotainment display shown in the product photographs

• A-Tach #50258: Only for the larger 8-inch infotainment display

Do not select the mount based only on the Terrain’s model year or trim name. Compare the size, shape and surrounding trim of your factory display with the individual product photographs and fitment information.

2010–2017 GMC Terrain Dash Mount

A-Tach #50487 is designed for the compatible dashboard shown on the product page. It is not compatible with Terrain models equipped with the smaller factory display.

Before ordering, compare your display, vents, controls and surrounding dashboard trim with all product photographs. The model year alone is not enough to confirm this mount.

Why the Terrain Display and Dashboard Matter

Vehicle-specific fitment is especially important for the GMC Terrain because display and dashboard differences can occur within the same model-year range.

Fitment can be affected by:

• Factory infotainment display size

• Display shape and surrounding bezel

• Center-vent arrangement

• Dashboard trim and mounting seams

• Location of nearby controls

• Available clearance for the holder and phone

• Complete dashboard redesigns between generations

For 2018–2024 models, identifying the smaller display or larger 8-inch display is essential. For 2010–2017 models, the available mount specifically excludes the smaller-display configuration.

Always use the product photographs as part of the compatibility information.

Vehicle-Specific Mounting for Everyday Travel

The Terrain is used for commuting, family transportation, road trips and daily errands. A properly selected dash mount creates a consistent location for a phone used for:

• Turn-by-turn navigation

• Hands-free calling

• Traffic and weather information

• Music and audio controls

• Compatible wireless charging

• Mileage and travel applications

• Delivery or work-related applications

The complete device position depends on the vehicle mount, phone holder, phone and protective case. Consider the combined size of these components when reviewing the illustrated mounting location.

Complete Your Two-Part Mounting System

An A-Tach mounting solution uses two components that are selected and purchased separately.

Part 1: Vehicle-Specific Dash Mount

The dash mount attaches at the compatible location in your GMC Terrain and provides the foundation for the mounting system.

Choose the vehicle mount according to:

• Your Terrain model year

• Your factory display size and style

• The dashboard shown in the photographs

• Your preferred device position

• The phone or device you intend to mount

Part 2: Phone or Device Holder

The separately purchased holder attaches to the vehicle-specific dash mount and holds your phone or another compatible device.

Holder choices may include:

• Adjustable clamp-style phone holders

• Holders for larger phones and protective cases

• Magnetic phone holders

• MagSafe-compatible holders

• Qi wireless charging holders

• Qi2 magnetic wireless charging holders

• Holders for compatible GPS units or other devices

Your Terrain’s dashboard and display determine the mount. Your phone, case and preferred features determine the holder.

A No-Drill Alternative to Universal Mounts

A-Tach Terrain mounts are designed to install without drilling holes into the dashboard or removing dashboard panels. The exact attachment method varies by product, so read the supplied instructions and test-fit the vehicle mount by itself before attaching a holder.

Unlike many universal mounting products, an A-Tach dash mount does not depend on:

• A windshield suction cup

• Permanent dashboard adhesive

• A cup-holder mounting base

• An ordinary vent-louver clip

• A long universal mounting arm

The result is a dedicated mounting platform designed around a compatible GMC Terrain interior.

Check Device Clearance Before Ordering

A-Tach provides photographs showing where each vehicle mount attaches. The final position and amount of space required, however, depend on the holder, phone and case selected by the customer.

Before ordering, consider:

• Phone height and width

• Protective-case thickness

• Holder width and depth

• Display visibility

• Access to nearby controls

• Vent airflow

• Steering-column or control-stalk clearance

• Charging-cable routing, when applicable

Always position and operate mounted equipment so it does not obstruct the driver’s view, cover essential controls or interfere with safe vehicle operation.

Frequently Asked Questions

Will one A-Tach mount fit every GMC Terrain?

No. The Terrain has used multiple dashboard generations and factory display styles. Select the correct model-year range and verify the display and dashboard before ordering.

Why does the 2018–2024 Terrain have two mount options?

GMC offered smaller and larger infotainment displays during this model-year range. A-Tach #50247 is for the smaller display style, while #50258 is for the larger 8-inch display.

How do I determine which 2018–2024 mount I need?

Compare your display size, bezel, vents and surrounding trim with the photographs and compatibility information for both mounts. Do not rely only on the trim level.

Does the 2010–2017 mount fit the smaller display?

No. A-Tach #50487 is not designed for 2010–2017 Terrain models equipped with the smaller display.

Will an older Terrain mount fit a 2025 model?

No. The 2025 Terrain uses a redesigned interior and requires the mount listed for 2025–current models.

Where does the 2025–current mount attach?

It fits in the compatible dashboard locations shown in the product photographs. Review all images to confirm the attachment area and device position.

Is the phone holder included with the Terrain dash mount?

No. The vehicle-specific dash mount and phone or device holder are purchased separately. This allows you to select a holder based on your phone, case and preferred features.

Can I use a MagSafe or wireless charging holder?

Yes. Compatible magnetic, MagSafe, Qi and Qi2 holders are available. Confirm compatibility with your phone, case and charging requirements.

Does installation require drilling?

A-Tach Terrain mounts are designed for installation without drilling holes into the dashboard. Always read and follow the instructions supplied with the specific mount.

Can I replace the holder when I get a new phone?

The two-part system allows you to replace the holder without necessarily replacing the vehicle-specific dash mount. Confirm compatibility between the replacement holder, mount and new device.

How can I avoid ordering the wrong Terrain mount?

Confirm the model year, identify the factory display and compare the entire dashboard area with all product photographs. Pay particular attention to display-size requirements and exclusions.

If you are uncertain about your Terrain’s display or dashboard, contact A-Tach Mounts with your model year and clear dashboard photographs before ordering.
