It may be caused by unstable power voltage in the car. Here are the detailed explanations: 1. Function: The car display screen is located on the car's center console and mainly displays car audio, navigation, vehicle information, reverse camera images, etc. It includes single-touch LCD screens and multi-touch LCD screens. 2. Check the navigation cable: If the voltage is stable, then check the cables on the back of the device for any issues. You can replace the connections to troubleshoot. If there are no contact issues, inspect the display cable of the device. If there is a problem, replace it with a new one for testing. If there is only no image but sound remains, it indicates that the power plug of the navigation display is loose. If there is no sound or image at all, the DVD may be damaged. 3. Usage notes: Ensure that cables are plugged or unplugged when the power is off. To maintain electrical stability and safety, the interval between turning the device on and off should not be less than 6 seconds. During use or storage, be careful with the surface polarizer of the LCD screen to avoid scratches from hard objects.

Do You Need to Press the AC Button When Using the Car Air Conditioner?

In summer, you need to turn on the AC for cold air, but in winter, you don't need it for warm air. Here is an introduction to how the air conditioning system works: 1. The AC button controls the air conditioning compressor. In summer, you must press the AC button to turn on the cold air. 2. Warm air, however, utilizes the car's internal heat circulation and does not require the air conditioning compressor to be activated. Therefore, to use warm air, you only need to adjust the air conditioning controls without pressing the AC button. 3. Switching between internal and external circulation is essential for long drives. The internal and external circulation functions help control the air quality inside the car and assist in maintaining temperature. 4. When controlling the air vents, drivers should follow these guidelines: point the vents upward when using cold air and downward when using warm air. 5. After the car has been exposed to the sun, avoid turning on the air conditioning immediately. It's best to open the windows first to ventilate and let the hot air escape before getting in and turning on the air conditioning.
