Plain answers to broader questions about WAMS — pricing, vehicle compatibility, warranty, programming approach, and direct ordering. For product-specific questions (exact compatibility, install steps, fitment notes for a particular module), the FAQ section on that product’s page is usually the fastest answer — that’s where most customer questions get resolved. This Global FAQ covers the site-wide questions that don’t sit naturally on any single product page. Many WAMS offerings ship brand-new, pre-programmed to your VIN, and priced below what a GM dealer charges for the bare module alone — and often below salvage-based aftermarket alternatives. If you can’t find your answer in either place, send us your VIN and the question and we’ll respond directly.
Pricing
How does WAMS pricing compare to a GM dealer?
WAMS is structured as an OEM-grade GM electronics wholesaler — every published price reflects wholesale module supply plus VIN-matched programming, not retail service department labor. Brand-new factory hardware, programming, and backend registration are bundled in one price. In many cases, the WAMS price for a fully programmed module is lower than what a GM dealer charges for the bare module alone, before any labor or diagnostic charges are added.
Is WAMS more expensive than other aftermarket options?
Usually no. The common assumption that brand-new OEM hardware must cost more than aftermarket alternatives doesn’t hold up in practice. Many of the larger aftermarket suppliers source their modules from salvage, and WAMS regularly comes in below their pricing while shipping brand-new OEM hardware with VIN-matched programming included. For most GM module replacements, WAMS delivers brand-new factory hardware at or below the price of a salvage-based alternative.
What’s included in the price of a WAMS module?
Every WAMS module ships with brand-new factory hardware, VIN-matched programming, and (where required) registration on the GM backend — bundled in one published price. In many cases, the WAMS price comes in below what a GM dealer charges for the bare module alone, before any labor or programming. Each product page lists the complete configured price for that specific vehicle.
Is there a separate trade or wholesale price for shops, fleets, and dealers?
No — there’s no separate trade tier. WAMS is already structured as a wholesaler, so the published price on every product page is the wholesale price for every customer type — independent shops, GM dealerships, fleet operators, collision centers, and individual customers all see the same number. For B2B workflow, technical contact, and direct ordering, see our B2B hub at /pros/.
Installation
Do I need a dealer visit to install a WAMS module?
Most installs do not require a dealer visit. WAMS modules ship pre-programmed and pre-registered to your VIN — bolt it in, plug it in, and the vehicle recognizes it as an OEM part. The module arrives with the same options and calibration the dealer would load. See our plug-and-play page for the operational detail.
Can I install a WAMS module myself, or do I need a shop?
Most module replacements (BCM, HMI, CSM, factory radios) are plug-and-play and can be installed by a confident DIY owner using basic hand tools. Cluster swaps and certain platform-specific retrofits are more involved and may benefit from a professional installer. Every product page lists install difficulty so you know what you’re working with before checkout.
How does plug-and-play installation work?
The module ships from WAMS already programmed to your specific VIN and registered on the GM backend. When you receive it, you remove the existing module, plug in the WAMS replacement using factory connectors, and the vehicle recognizes it immediately as an OEM part. The install integrates with the vehicle’s existing wiring exactly as the original factory module did.
What if my install requires a final setup step?
For certain Global B upgrades — particularly digital cluster swaps — a brief in-vehicle setup procedure is required after installation. WAMS ships detailed written instructions with every order that requires one. Following the steps as outlined ensures proper system initialization. For Global B / VIP vehicles, see our Global B / VIP Terms of Service for the complete operational guidance.
Vehicle compatibility
How do I know if my vehicle is Global A or Global B?
Most pre-2020 GM vehicles run on Global A architecture; most 2020+ cars and SUVs and 2022.5+ full-size trucks run on Global B (also called VIP). The full lookup by model and year is in our Global A vs. Global B identification guide. If you’re not sure, send us your VIN and we’ll confirm in about 60 seconds.
Does WAMS work on my specific GM model and year?
WAMS services GM vehicles across both Global A and Global B architectures, from 2010-era models through current production. Specific compatibility varies by module type — every product page on the site lists exact model/year compatibility. If your vehicle isn’t explicitly listed, contact us with your VIN and we’ll confirm what’s possible.
Does WAMS work on Ultium EVs?
Yes. Ultium-platform EVs (Cadillac Lyriq, Escalade IQ, Optiq, Celestiq, Chevrolet Blazer EV, Equinox EV, Silverado EV, GMC Hummer EV, Hummer EV SUV, Sierra EV, and others) are all built on Global B architecture. WAMS provides module replacement and programming services for these vehicles, with full Global B / VIP install considerations published in our Global B / VIP Terms of Service.
What if my vehicle is on the older HMI or CSM infotainment?
WAMS specializes in HMI (2013–2019 Bosch infotainment) and CSM (2017.5+ infotainment) module replacement, with brand-new factory hardware and VIN-matched programming for both. See our HMI vs. CSM infotainment guide for the platform breakdown, or browse HMI module replacement and CSM module replacement directly.
Warranty
What warranty comes with WAMS modules?
WAMS modules carry the OEM 1-year GM parts warranty, administered by GM. The warranty is tied to your vehicle’s VIN at the time of programming, which is what makes the module behave as a factory part on dealer service tools. WAMS also covers programming errors at no charge per our store policies.
Programming and process
What does VIN-matched programming mean?
WAMS pulls your vehicle’s specific build data from GM’s backend — every option code, calibration, and feature configuration unique to your VIN — and configures the replacement module with the same data before it ships. The module arrives with the exact software state the dealer would load, registered to your vehicle, and ready to integrate plug-and-play.
Do I need to send in my old module first?
For most products, no — WAMS modules ship from inventory configured to your VIN. For certain upgrades that involve a hardware exchange, the product page indicates whether ship-in is required and collects the necessary checkbox confirmation at checkout.
How long does shipping take?
Most WAMS orders ship within published lead times listed on each product page. Programming and configuration are completed before the module leaves the facility, so the lead time accounts for both fulfillment and programming.
Can WAMS program a used module I already have?
WAMS uses brand-new OEM hardware as the standard so every install ships with a known software baseline, factory-correct configuration, and the GM warranty registration intact. For specific custom programming services across Global A and Global B platforms, see custom module programming for what’s available.
For shops, fleets, dealers, and collision centers
How do shops, fleets, or dealers work with WAMS?
WAMS functions as an OEM-grade GM electronics wholesaler for independent shops, GM dealerships, fleet operators, and collision centers. Modules ship pre-programmed and pre-registered to the customer’s VIN — your bay handles the install, WAMS handles the programming. See our B2B hub for the full picture.
Why do some GM dealers work with WAMS?
WAMS provides specialized OEM-grade module supply and VIN-matched programming that complements a dealer’s service department on jobs that benefit from outside engineering depth — mid-cycle hardware changes, factory upgrades, and complex retrofits among them. Brand-new factory hardware, VIN-matched programming, and backend registration mean the result behaves as if installed at the factory while routing the work through WAMS’s specialty workflow.
Can WAMS standardize configurations across a fleet?
Yes. GM platforms evolve continuously across model years, and WAMS specializes in mapping those configuration changes so each replacement module ships pre-programmed for the specific VIN it’s going into. The result is consistent, factory-correct configurations across your fleet without hunting down platform-specific calibrations on each vehicle. See our B2B hub for fleet-specific service.
How do shops or fleets set up direct ordering with WAMS?
WAMS prices on the site are already wholesale, so there’s no separate trade application or discount tier to apply for. For shops, fleets, dealers, and collision centers that want a direct technical contact and ongoing volume relationship, contact us and we’ll set that up. Start at our B2B hub or contact us directly.
