There are a couple of reasons why the touchscreen in a 2012 Toyota Camry might stop working, and it would be helpful to have more information to pinpoint the issue. For instance, it's important to clarify how the touchscreen is malfunctioning - is it displaying a black screen, not responding to touch, or not coordinating with the other car functions (such as speakers not working)? If the entire screen remains black, it's likely that the head unit or touchscreen has failed, and the only solution might be to replace it entirely. If you see a blue screen, it suggests a software malfunction that might need the system to be reprogrammed, but it's unclear if dealers can handle this. In sum, the problem could range from a simple wiring problem to a major system failure, but without more specific details, it's hard to determine the exact cause.
