Cadillac infotainment systems have service menus that most owners never see.
Follow these simple steps:
- Turn the ignition on but don’t start the engine.
- Press and hold the Home + Fast Forward buttons on the infotainment screen for about 10 seconds.
- The service menu will appear with system diagnostics, firmware versions, and reset options.
Pro Tip: Be careful—changing settings here can affect vehicle functions.
