What are the reasons for the malfunction of the car navigation touch screen?
2 Answers
There may be a situation where the touch screen is damaged or there is a vehicle body malfunction. The following is a related introduction to car navigation: 1. Introduction: A car navigation system (Car-Navigation) is a driving assistance device that can help users accurately locate their current position and calculate the itinerary based on the set destination, guiding users to the destination through map display and voice prompts. The operation of the car navigation system mainly relies on the Global Positioning System (GPS). The car navigation system is mainly composed of a chip, antenna, processor, memory, and screen. 2. Common functions: map query, route planning, automatic navigation.
I've encountered several instances of in-car navigation touchscreen malfunctions, which I believe are primarily related to hardware aging. For example, after prolonged use, the screen surface may develop scratches or internal components may become loose; if the cables connecting the screen aren't securely plugged in or get shaken loose, the signal can't transmit properly, resulting in unresponsive touch. Additionally, in extreme temperature conditions, the screen may harden in cold weather, while direct sunlight in hot weather can cause components to overheat and fail. I recommend gently wiping the screen with a soft cloth during each car wash, avoiding pressing too hard to prevent damage. If malfunctions persist, it's best to have a professional check the circuits and connections to ensure everything is functioning properly, which can prevent minor issues from escalating into major problems.
