Factory-new, VIN-programmed Global B CSM replacement modules for your 2020–2024 Cadillac CT4. Plug-and-play installation — no dealer visit, no programming appointment, no downtime.
Is Your Cadillac CT4 Infotainment System Failing?
The 2020–2024 Cadillac CT4 is built on GM’s Alpha 2 platform. While it’s a capable compact luxury sedan, the infotainment system — powered by the Global B CSM — is a known failure point. These modules process every interaction with your touchscreen, navigation, backup camera, Bluetooth, and connected phone services. When the module fails, you lose access to all of it.
If your Cadillac CT4 is showing any of the symptoms below, you’re almost certainly dealing with a failing infotainment module — not a fuse issue, not a software glitch, and not something a dealer software update will fix permanently.

Why Replace Your Module with WAMS?
White Automotive & Media Services (WAMS) is not a parts reseller. Every module is sourced as brand-new OEM GM hardware, then custom-programmed to your exact VIN before it ships. That means your replacement arrives with the correct software version, calibration files, and feature configuration for your specific Cadillac CT4 — including trim-specific features like navigation, CUE, and connected services.
✅ VIN-Programmed
Matched to your exact vehicle
📦 Plug & Play
Self-install in 20–40 minutes
🛡️ Factory New OEM
Not salvage or remanufactured
🔧 No Dealer Required
No programming appointment
WAMS vs. Dealership Replacement
Most GM dealers will charge $800 to $1,500+ for a module replacement — and that’s before the labor charge for programming. You’ll also wait for the part to arrive, schedule an appointment, and leave your Cadillac CT4 at the dealer for hours or days. With WAMS, the module arrives pre-programmed and ready to install yourself. No appointment, no labor charge, no waiting.
WAMS vs. Salvage / Remanufactured Modules
Salvage modules pulled from wrecked vehicles are cheap for a reason — they carry the previous vehicle’s programming, may have hidden damage, and often fail again within months. Remanufactured modules are only marginally better. WAMS uses exclusively brand-new GM hardware with a full factory warranty. Every module is programmed fresh to your VIN.
