Every conversation about whether a GM vehicle can be upgraded, retrofitted, or have a replacement module installed without a dealer visit comes down to one question: is it built on Global A or Global B? The answer is mostly determined by model and year, but the line falls in different places for different vehicle families — and a few model years straddle the transition. Use the lookup below to identify which architecture your GM vehicle has, and see the future of GM electronics for what each architecture means for your upgrade options.
Some models appear in both lists with different year ranges — that means the model spanned the architecture transition mid-life (Tahoe, Suburban, Yukon, Escalade, Silverado 1500, and others). For questions about which infotainment family is in your specific vehicle (HMI, CSM variants, Google built-in, IOR, IOK), see our separate HMI vs. CSM infotainment guide. This page answers architecture only.

Global B / VIP vehicles (OTA-capable, security-validated platform)
Global B vehicles include both ICE models and Ultium-platform EVs (tagged Ultium EV below). The architecture is identical regardless: OTA updates, security validation, VIN-matched programming, and dealer-cloud integration. Infotainment hardware and software vary across Global B in ways that aren’t relevant to the architecture question — for that detail, see our HMI vs. CSM infotainment guide.

Three ways to confirm at home
1. Look for Google built-in on your infotainment
If your vehicle’s infotainment system has a Google Maps tile, a Google Assistant voice prompt, or a native Google Play Store, you are on Global B (VIP). Google built-in only ships on Global B. The reverse isn’t true — many Global B vehicles run a non-Google infotainment that looks very similar to what Global A vehicles run, so if your dash doesn’t have Google built-in, use steps 2 and 3 to distinguish Global A from Global B.
2. Check your Settings for over-the-air updates
Open your vehicle’s Settings menu and look for an Updates or Software Updates section. If your vehicle reports that it can receive over-the-air updates — or has actually received one — you are on Global B (VIP). Global A vehicles do not support module-level over-the-air updates. Updates on Global A vehicles, when needed, are loaded by USB at home or by a dealer service visit.
3. Check the RPO/SPID label or send us your VIN
GM vehicles carry two related build-option labels: the RPO (Regular Production Option) label and the SPID (Service Parts Identification) label. Both are usually found in the glove box or trunk lid, but they list different things and are read differently. For a full breakdown of which is which and how to read each one, see our guide to GM RPO labels vs. SPID labels. The cleanest way to confirm your architecture overall is to send us your VIN — we pull build data on every vehicle we work on, and identifying Global A vs. Global B from a VIN takes us about 60 seconds.
What this means for your upgrade options
If you have a Global A vehicle
You’re on the retrofit-friendly platform. Multiple retrofit paths are typically viable for the same vehicle, and most module work is on the menu. Our policy of stocking brand-new factory hardware only — no salvage, no “tested” pulls — means availability holds longer for our customers than for shops sourcing from scrapyards. For framework on which retrofit path makes sense for your specific situation, see our Global A vs. Global B retrofit decision guide.
What we offer for Global A vehicles:
- Wireless CarPlay and Android Auto retrofits on factory radios
- CarPlay and Android Auto retrofit hub
- Digital cluster upgrades
- HMI and CSM module replacement
- BCM programming and replacement
- Navigation retrofit solutions
- Rear seat entertainment
- Steering wheel and interior upgrades
- Cadillac CUE repair and replacement
- 2014–2015 C7 Corvette CarPlay / Android Auto upgrade
- Camaro OEM upgrades
If you have a Global B / VIP vehicle
OEM-correct module replacement and VIN-matched programming are squarely in our lane. Brand-new factory hardware ships configured to your specific VIN, registered on the GM backend, and ready to install plug-and-play. We work with GM’s security validation rather than around it, which is what keeps our Global B installs clean over the long run through the vehicle’s full electronics lifecycle. The result behaves as if installed at the factory.
What we offer for Global B vehicles:
- Tahoe, Suburban, and Yukon upgrades for 2021+ full-size SUVs
- Silverado and Sierra upgrades for 2022.5+ refresh trucks
- Escalade premium upgrades for 2021+ Escalade
- C8 Corvette upgrades and parts
- Digital cluster upgrades across Global B vehicles
- CSM module replacement with VIN-matched programming
- BCM programming and replacement
- Cluster programming services
- Custom module programming
- Infotainment screen replacements
- Navigation retrofit solutions
- Rear seat entertainment
- Steering wheel and interior upgrades
Custom VIN-programmed work carries tighter return policies than off-the-shelf parts — that’s the cost of getting it right the first time, and we’d rather have that conversation up front than after the box is open.
Still not sure?
Send us your VIN and we will tell you exactly which architecture your vehicle is on, what’s possible, and what isn’t. Identification is free; getting it right the first time keeps you from buying twice.
