Plug-and-Play GM Upgrades – No Dealer Required

One of the biggest advantages of buying from WAMS is that most of our modules install without any additional dealer programming. We program every module to your specific VIN, RPO codes, and vehicle architecture before it ships. That means when it arrives, you bolt it in, plug it in, and it works.

This page highlights our most popular plug-and-play solutions: Denali/High Country cluster upgrade kits, Apple CarPlay and Android Auto retrofits, HMI replacement modules, wireless connectivity upgrades, and steering wheel upgrade kits. If a specific product does require additional dealer steps, that’s clearly documented on its product page so there are no surprises.

No core charges. No mystery used modules. No dealer appointment. Just new GM hardware, programmed to your VIN, ready to install.
