The reasons for a black screen with sound in the navigation system: 1. System crash caused by unstable working voltage of the motherboard; 2. Damaged touch screen; 3. The decoding chip or core module is not working or damaged; 4. Loose power plug of the navigation display. The car navigation system has the GPS global satellite positioning system function. Once the destination is input into the car navigation system, the system will automatically calculate the route based on the electronic map and remind the driver to follow the calculated route during the vehicle's movement. The car GPS navigation system consists of two parts: one part is composed of the GPS receiver and display device installed in the car; the other part is composed of the computer control center, and the two parts are connected via positioning satellites.

What are the consequences of brake cylinder air leakage?

Brake cylinder air leakage can affect braking performance and is unsafe. Here is the relevant introduction: 1. Brake booster pump: The brake booster pump, also known as the brake assist pump, controls the vacuum entering the booster pump during braking, causing the diaphragm to move. Through the linkage device, the pushrod on the diaphragm assists the driver in pressing and pushing the brake pedal, thereby amplifying the force applied by the driver. 2. Causes of damage: The common causes of cylinder damage are oil leakage or poor return. Oil leakage can be easily identified, while poor return can be judged based on the wear condition of the brake discs and pads.
