This creates a digital divide; while tech-savvy users can easily unlock new features—such as UI tweaks, improved voice recognition latency, or support for rear-view camera overlays—less experienced users may find the process daunting. It highlights a drawback of the aftermarket ecosystem: the user assumes the role of system administrator for their vehicle.
