Truckers spend more time behind the wheel than almost anyone, and satellite radio is one of the best investments you can make for a long-haul cab. But installing Sirius XM in a truck or rig is meaningfully different from doing it in a car. The cabin is larger, the distance from windshield to driver is greater, the vibrations are more intense, and the antenna situation requires more thought. This guide covers the complete setup: the right dock kit, three proven mount options sized for commercial cabs, and how to handle the antenna correctly so you get reliable reception mile after mile.
| Component | Best Option | Why It Works for Trucks |
|---|---|---|
| Dock & Charger | SiriusXM SXDV3 Kit | Powers the radio; works with most modern Sirius XM dock-and-play units |
| Windshield Mount | Arkon SR2CM117 Extendable Suction Mount | 14.5″ to 18.5″ arm clears long dashboards; all-metal construction handles vibration |
| Seat Bolt / Floor Mount | Arkon 22″ Gooseneck Seat Rail Mount | Keeps radio off the dash; bendable aluminum arm holds position; includes AMPS adapter |
| Dashboard Mount | Arkon Sticky Suction Dash Mount | No drilling; bonds to smooth or textured dash surfaces; fully repositionable |
| Antenna (inside cab) | Windshield Suction Cup Antenna Mount | Inside-cab install; no exterior routing; five-minute setup |
| Antenna (best reception) | Browning BR-Trucker Mirror Mount Antenna | Outside-cab install on driver mirror; unobstructed sky view; built specifically for rigs |
Start With the Right Dock Kit
Before picking a mount, you need a dock: the cradle that holds your Sirius XM radio and delivers power to it. The SiriusXM SXDV3 Vehicle Dock and Charging Kit is the standard starting point and works with the majority of Sirius XM dock-and-play radios released in the past several years, including the Onyx Plus, Onyx EZ, Edge, Stratus 7, 6, and 5, Sportster 5, and Starmate 8, 5, 4, and 3.
The kit includes the car dock cradle, a charging cable, a magnetic satellite antenna, and suction cup and vent mount hardware. In a truck install, you will use the cradle and the charger. The charger connects to your accessory port and into the cradle itself, keeping the radio powered through long hauls. The included mount hardware is designed for a passenger car and will not serve you well in a commercial cab, which is exactly what the rest of this guide covers.
One thing worth confirming before ordering: check that your specific radio model is compatible with the SXDV3 dock. Most modern Sirius XM radios are, but if you have an older unit it is worth verifying on the product page before purchasing.

Choosing Your Mount
This is where truck installs diverge sharply from a car setup. The three options below each suit a different preference for where you want the radio positioned in the cab. All three are compatible with the SXDV3 cradle and with any other Sirius XM radio dock that uses a Single-T or 4-hole AMPS mounting pattern.
1. Arkon SR2CM117 Extendable Windshield Mount — Best for Most Trucks
The Arkon SR2CM117 Extending Windshield Suction Mount is the most versatile option and the one pictured at the top of this article. What makes it work specifically for trucks is the aluminum shaft, which extends from 14.5 to 18.5 inches. That range is long enough to bridge the distance from your windshield to a comfortable viewing position in a wide cab without the radio sitting awkwardly close to the glass or blocking your sightline.
The suction cup base is 80mm with a locking lever mechanism that keeps it planted on rough roads. At the tip, the mount includes both a Single-T connector and a 4-hole AMPS adapter, so it will attach to virtually any Sirius XM radio cradle on the market regardless of radio model. The arm rests against the dash, which adds a second point of contact and cuts down on vibration. Installation is simple: clean the windshield, press the cup firmly, engage the locking lever, and snap your cradle onto the mount tip.
2. Arkon 22″ Gooseneck Seat Rail Mount — Best for a Low Mounting Position
If you prefer the radio positioned lower in the cab and closer to your controls rather than up on the windshield, the Arkon GN088-SBH-AMPS-L22 is the right call. This mount bolts to the seat rail using the existing seat track bolt, and the 22-inch flexible aluminum gooseneck gives you enough reach to position the radio exactly where you need it. The gooseneck bends to any angle and holds that position once set. A 360-degree swivel ball at the top lets you dial in tilt and rotation without having to re-bend the arm.
A few installation details worth knowing upfront: use a socket wrench to tighten the seat rail bracket, not your hands. Hand-tight will not hold the weight of the radio under road vibration and the mount will shift. The package includes a 4-hole AMPS adapter head, which is what attaches to the SXDV3 cradle and most other Sirius XM radio docks. Note that mounting screws are not included and will need to be purchased separately, though standard hardware store bolts work fine.

3. Arkon Sticky Suction Dash Mount — Best for a Clean, Low-Profile Look
The Arkon SR279 Sticky Suction Dash Mount uses a polyurethane gel and suction combination that bonds firmly to both smooth and textured dashboard surfaces without drilling, permanent adhesive, or any hardware. It is the cleanest-looking install of the three options and works particularly well on the large flat dash surfaces common in truck cabs. An optional 3M adhesive disk is included if you prefer a secondary attachment layer on vinyl or leather surfaces.
One maintenance note that will extend the life of this mount considerably: if the sticky base loses grip over time, rinse it with warm soapy water, let it air dry completely, and the tackiness fully restores. This works repeatedly. As with the other mounts here, the cradle attachment hardware covers Single-T and 4-hole AMPS patterns, so it connects to any standard Sirius XM radio dock.

The Antenna: The Part Most Guides Skip
The antenna is where truck installs are more complicated than cars, and it deserves more attention than it usually gets. You cannot simply pop an antenna on the roof and run a wire through a window seal the way you might on a passenger vehicle. Here are the two best options for a commercial cab, covering everything from a five-minute inside-cab install to the strongest possible reception for drivers logging serious miles in difficult terrain.
Inside the Cab: Simple and Effective
You do not have to run the antenna outside the vehicle to get reliable reception. Satellite radio signals only require a clear line of sight to the sky, and they pass through glass without meaningful signal degradation. The Windshield Suction Cup Antenna Mount holds the antenna flat against the inside of your windshield, pointing upward toward the satellites. The flat mounting platform includes attachment strips for proper antenna positioning. Tuck the cable behind the headliner for a clean look. Setup takes about five minutes and works reliably on open highway routes.
Outside Mirror Mount: Best Reception
If you want the strongest possible signal, particularly on routes with mountain terrain, heavy tree cover, or dense urban corridors where signal dropout is a regular problem, the Browning BR-Trucker Satellite Radio Mirror Mount Antenna is the right solution. It clamps directly to the driver-side mirror on the outside of the cab, giving the antenna a completely unobstructed view of the sky in all directions. No glass between the antenna and the satellites.
The Browning is built specifically for trucking: heavy-duty construction, a 10-inch tall antenna with a large built-in ground plane, a three-way stainless steel mirror mount with bolts, and 17 feet of premium RG-58/U coaxial cable with an SMB-female connector. The cable routes along your door seal and into the cab. Installation takes more effort than the inside windshield option, but the reception improvement is significant and well worth it for drivers who regularly encounter signal loss with a standard setup.

Frequently Asked Questions
Can I use a regular car Sirius XM mount in my truck?
Technically yes, but it is not a good fit. Standard car mounts are too short for most truck cabs, the arm does not extend far enough to position the radio at a comfortable viewing distance from the driver, and they are typically built with more plastic than metal. They are not designed for the vibration levels found in a commercial truck environment and will move around over time. The mounts recommended here are specifically selected because they are long enough, sturdy enough, and built to last in a demanding cab.
Do I need a new cradle for my Sirius XM radio?
In most cases no. The SiriusXM SXDV3 dock kit includes a car cradle that works with the majority of modern dock-and-play radios and attaches to any of the mounts recommended above. The cradle and vehicle mount are separate components, so if you already have a cradle that fits your radio, you may only need the mount itself.
Does the antenna work from inside the cab?
Yes. Satellite radio signals pass through glass without significant degradation. Placing the antenna on the inside of the windshield pointing upward gives it a clear line of sight to the satellites and produces reliable reception in most conditions. The Browning outside mirror mount will outperform an inside-mounted antenna in difficult signal environments, but for the majority of truckers on open highway routes the inside windshield mount works well.
What if my seat rail bolt is not accessible?
Not all truck seats have an exposed seat rail that is easy to reach. If the rail is covered by trim or carpet, the Arkon SR2CM117 windshield mount or the Arkon sticky suction dash mount are the practical alternatives. Both install without any access to floor hardware and work in any cab configuration.
The seat rail mount says screws are not included. What do I need?
The Arkon GN088-SBH-AMPS-L22 ships with the seat rail bracket and AMPS adapter but not the bolts needed to secure the bracket to the rail. Standard metric hardware works. Check the diameter and thread pitch of your seat rail bolt before heading to the hardware store, or confirm the specs in the product manual before ordering.
Is the SXDV3 compatible with all Sirius XM radios?
It works with the majority of dock-and-play radios released in the past several years, including the Onyx, Onyx Plus, Onyx EZ, Edge, Stratus series, Sportster 5, and Starmate series. Older or specialized radios may use a different dock connector, so verify compatibility on the Amazon product page before purchasing if you have an older unit.
