Here are some tips for dealing with a malfunctioning central control touchscreen: 1. Incomplete removal of the screen protector: Residual film adhering to the surface can affect sensitivity. This is the easiest issue to resolve—simply remove the screen protector completely. 2. Issues with the screen itself: There can be various causes for this, such as damage to the touchscreen itself, faulty wiring, or loose connections, among others. Most problems caused by the screen itself require professional inspection and repair at a specialized repair shop or 4S dealership. 3. Prolonged use of the screen: You can use a paperclip or toothpick to press the RST hole (reset button) on the central control screen, effectively restoring it to its initial state. Afterward, reinstalling the system should allow normal use.
Oh man, I know this issue all too well! Last year my car's touchscreen was acting crazy like it had a mind of its own. First try holding the volume button for 15 seconds to force restart - same logic as when your phone freezes. If that doesn't work, check if your tempered glass screen protector has air bubbles, especially in hot weather when the edges lift up and interfere with touch sensitivity. Pro tip: wipe your fingers clean of oil and sweat before trying - once I couldn't get any response after eating fried chicken! For deeper fixes you'll need to remove the center console, but don't go poking around blindly - I ended up with three extra screws after my DIY attempt. The ultimate solution? Disconnect the negative battery terminal for five minutes - it's like giving your infotainment system a deep spa treatment. My neighbor Old Wang saved 800 bucks in repair fees with this trick!
