Installing a dash cam without a rearview mirror is because the dash cam is not connected to the vehicle. The dash cam is not connected to the vehicle: If the dash cam is powered by a battery and not connected to the vehicle, the rearview function cannot be activated. In this case, the dash cam needs to be connected to the car, and the rearview function must be properly set up for it to display correctly. This type of installed dash cam is usually mounted on the rearview mirror. When the screen is turned off, it can function as a rearview mirror, but the screen must be turned off, which does not affect the dash cam's normal recording function. Damaged camera: If the rear camera of the vehicle is damaged, the dash cam cannot display the rear view. There are many reasons for camera damage, and it is necessary to have it inspected and repaired by professionals at a repair shop. When the car is not started, the dash cam has no power. Only after the car is started and the dash cam is properly powered can the rearview function be used normally.

How to Repair a Cigarette Lighter That Has No Power?

Below is an introduction regarding the reasons why a cigarette lighter may have no power, as well as how to resolve and avoid such incidents: 1. During use, plugging and unplugging may cause the curved spring plate of the external device's plug to deform, resulting in loose contact after insertion and affecting conductivity. The symptom is intermittent connection. Solution: Adjust the angle of the curved spring plate on the plug. If this doesn't work, it is recommended to seek assistance from a 4S shop. 2. How to avoid such incidents: (1) After using an external device, leaving it plugged into the cigarette lighter before turning off the engine can undoubtedly cause trouble. At the moment of vehicle startup, external devices on the cigarette lighter are prone to burning out due to the high current surge, especially MP3 players and USB drives, which are highly susceptible to issues. Therefore, it is advisable to unplug the device after use and plug it back in only after the car has started. (2) Depending on the vehicle's settings, some cigarette lighter power sources do not turn off when the vehicle is turned off, and many vehicles still have power. Thus, leaving external devices plugged into the cigarette lighter for extended periods is not a wise choice. The best practice is to plug in the device when in use and unplug it after use, avoiding prolonged insertion into the cigarette lighter socket to enhance the safety of external devices.

Does Clay Bar and Waxing Damage Car Paint?

Clay bar and waxing can cause minor damage to car paint. A car's paint surface consists of four layers, from inner to outer: the electrocoat layer, primer layer, basecoat layer, and clearcoat layer. Clay bar treatment involves using clay to remove surface contaminants such as iron particles, overspray, asphalt, or spots from the paint before applying wax. The primary benefits of car waxing are waterproofing and acid rain protection. The wax coating significantly reduces water droplet adhesion on the car body, with effectiveness ranging from 50% to 90%. Additionally, it provides protection against high temperatures and UV rays. As weather gets hotter, cars exposed to sunlight for prolonged periods are prone to paint fading and aging. The wax film reflects some light, effectively preventing paint deterioration.
