Real-world difference with the 12U configuration

I have seen this on a similar GMC Sierra 1500. The basic description was correct, but one related feature was part of a separate package. I would not assume the code includes every item mentioned in marketing material.

The wording may be abbreviated because these were originally production codes rather than consumer descriptions. “Primary exterior color: Galaxy Silver Metallic. This code identifies the vehicle's factory-applied main exterior paint color” is a reasonable plain-English reading, but the exact implementation should be verified for the 2022 model.

For a retrofit, check the modules, wiring connectors, software configuration, and compatible part numbers first. Installing the visible component alone may not make the feature operational.

I would avoid buying retrofit parts until the connectors and module support are confirmed. Returning electronic or VIN-programmed components can be difficult.

If you are documenting the vehicle, save both the original wording and the readable explanation. That preserves the factory terminology while making the record understandable later.

I found a second document with the same code, so it looks like the original configuration is confirmed. The marketing name was what caused the confusion.
