Digital cluster upgrades, Apple CarPlay & Android Auto retrofits, navigation activation, HD Radio, screen upgrades, and wireless connectivity packages.
OEM Level Quality
Brand-new GM parts, dealership-grade diagnostic tooling, and VIN-specific programming. Every module we ship works as if the dealer installed it — because we use the same process.
Global B Programming & Upgrades
Global B is GM’s newest electrical architecture. It requires Techline Connect — GM’s subscription-based diagnostic platform — to marry new modules to the vehicle. Unlike older GM vehicles where many upgrades are plug-and-play, Global B vehicles need factory-level programming for any module swap or upgrade. Most independent shops and even many GM dealers are not equipped to handle Global B programming for upgrades and retrofits.
WAMS is one of the only independent facilities in the country performing Global B programming for aftermarket upgrades.
Global B vehicles include: 2022.5+ Chevrolet Silverado, 2022.5+ GMC Sierra, 2021+ Chevrolet Tahoe, 2021+ Chevrolet Suburban, 2021+ GMC Yukon, 2021+ GMC Yukon XL, 2021+ Cadillac Escalade, Cadillac CT4, Cadillac CT5, and 2020+ Chevrolet Corvette (C8).
12.3-Inch Digital Cluster Upgrade — 2022.5–2026 Silverado & Sierra
Upgrade your 2022.5–2026 Silverado or Sierra from the base analog cluster to the full 12.3-inch digital cluster display — the same cluster found in High Country and Denali trims. WAMS supplies a brand-new OEM cluster and performs the complete Techline Connect marriage, VIN calibration, mileage transfer, and security credential setup. This is not a plug-and-play swap — it requires factory-level programming that WAMS handles before shipping.

Navigation & HD Radio Upgrade — 2022.5+ Trucks & SUVs
Add factory navigation and HD Radio to 2022.5+ Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade models that did not include these features from the factory. Programming-only service — no hardware swap required on compatible vehicles.

Video Processing Module (VPM) Programming — 2022.5+ Trucks
The VPM controls camera feeds, surround vision, and display routing. If you’re replacing a VPM, adding surround vision, or upgrading camera functionality on a 2022.5+ truck, the new module must be married to the vehicle through Techline Connect. WAMS handles the full VPM programming, calibration, and feature activation.

Steering Wheel Upgrade — 2022.5–2026 Silverado & Sierra
Upgrade to a heated, leather-wrapped, or premium trim steering wheel. Includes all necessary programming to enable heated steering wheel functionality and configure controls for your vehicle’s specific option content.
How to Tell If Your Truck Is Global B (2022.5+ Refresh)
For 2022 Silverado and Sierra pickups, year alone is not enough to determine your vehicle’s architecture. GM produced both pre-refresh and refresh trucks during the 2022 model year.
Check your VIN: Look at the last 8 digits of your VIN. If they begin with NG5, NZ5, NG6, or any sequence higher than NG6, your truck is a 2022.5+ refresh model with Global B architecture. If the last 8 digits begin with a lower sequence, you have a pre-refresh truck.
Visual identification: Refresh trucks have a redesigned front fascia, updated interior trim, and a revised infotainment screen layout. However, VIN verification is always the definitive method.
2021+ full-size SUVs (Tahoe, Suburban, Yukon, Yukon XL, Escalade) are all Global B — no VIN check needed for those.
Not sure? Send us your VIN and we’ll confirm your architecture and compatible upgrades in minutes.

Custom Module Programming
Don’t see your exact vehicle or module listed? WAMS offers custom programming for virtually any supported GM module. With over 20 years of exclusive GM electronics experience and access to GM’s full diagnostic software suite, we can program, configure, and validate most GM control modules.
Common custom requests include feature activation, option content changes, VIN reprogramming, module pairing, security credential setup, and configuration for modules that have been swapped between vehicles. Contact us with your VIN and a description of what you need — we’ll confirm compatibility and provide a quote.
Why WAMS for GM Programming
GM-exclusive focus. We don’t program Fords, Toyotas, or BMWs. Every tool, every software license, and every hour of experience is dedicated to GM vehicles. This specialization means we’ve seen configurations and edge cases that generalist shops will never encounter.
Dealership-grade tooling. WAMS uses the same GM diagnostic platforms that authorized dealerships use — including Techline Connect for Global B, GDS2 for older architectures, and Tech2 for legacy platforms. No cloned tools, no cracked software, no aftermarket workarounds.
Brand-new OEM parts only. Every module, cluster, radio, and HMI unit we sell is brand-new genuine GM hardware. No salvage pulls, no refurbished units, no aftermarket substitutes.
VIN-specific programming. Every module ships pre-programmed to your vehicle’s exact VIN — with correct mileage, option content, security credentials, and calibration data.
No dealer visit required. For most applications, our modules are plug-and-play. Install it yourself or have any shop do it. The exception is Global B modules that require a Techline Connect marriage procedure, which we coordinate before shipping.
Frequently Asked Questions
What is Global B and why does it matter?
Global B is GM’s newest electrical architecture, found in the 2022.5+ Silverado and Sierra, 2021+ Tahoe, Suburban, Yukon, Escalade, CT4, CT5, and C8 Corvette. It uses a completely different security and communication protocol than older GM vehicles. Any module replacement or upgrade on a Global B vehicle requires Techline Connect — GM’s subscription diagnostic platform. Most shops don’t have it. WAMS does.
Can I upgrade the cluster on my 2022.5+ Silverado or Sierra?
Yes. WAMS offers a 12.3-inch digital cluster upgrade for 2022.5–2026 Silverado and Sierra. It replaces the base analog cluster with the full digital display found in Denali and High Country trims. This requires Techline Connect programming — WAMS handles everything before shipping.
How do I know if my 2022 truck is a refresh model?
Check the last 8 digits of your VIN. If they begin with NG5, NZ5, NG6, or higher, you have a 2022.5 refresh truck with Global B architecture. Earlier 2022 production trucks use the older architecture. Send us your VIN if you’re unsure and we’ll confirm.
Do I need to visit a dealer after installing a WAMS module?
For most applications, no. WAMS modules ship pre-programmed to your VIN for plug-and-play installation. Global B upgrades that require an on-vehicle marriage procedure are the exception — WAMS coordinates that process and provides clear instructions.
What’s the difference between WAMS and a GM dealer?
We use the same diagnostic software and calibration files. The difference is that WAMS specializes in upgrades, retrofits, and custom configurations that most dealers either can’t do or refuse to do. Dealers handle warranty work and standard replacements — they won’t program a Denali cluster into your base-model truck or custom-configure a BCM. WAMS will.
Can WAMS program a module I purchased elsewhere?
Yes. WAMS offers standalone programming services for customers who sourced their own hardware. Send in your module and we’ll program it to your VIN with the correct calibration, option content, and security credentials. Available for clusters, BCMs, HMI modules, radios, and most other GM control modules.
