Perhaps the working time is too long, it is recommended to turn off the device and let it rest for a while, then reset it. Press and hold the power button for more than 5 seconds. If the screen does not light up and the power LED green light does not turn on or immediately turns off, it indicates the battery is out of power. Use the standard adapter to charge it.

Last time during a long-distance drive, the navigation suddenly went black. I figured out a few key points. First, check the power supply: see if the cigarette lighter plug is loose or if there’s dirt in the USB port. Second, force a restart: hold the power button for more than 10 seconds; some models require pressing the volume button simultaneously. Third, inspect the fuse: look for a 10A fuse labeled 'NAVI' or 'AUDIO' in the manual—spare fuses are usually hidden inside the fuse box cover. If the wiring has been modified, prioritize checking the connections of aftermarket devices. Once, a client’s navigation went black because a small spider had spun a web on the screen’s ribbon cable connector, causing a short circuit. In summer and autumn, static electricity and overheating can also trigger protective shutdowns—parking and turning off the engine for half an hour often helps.

Is October a Good Time to Switch to Snow Tires?

For car owners in northern regions, October is the ideal time to switch to snow tires because the temperature difference between day and night is very significant in the north, and you don't need to wait until it snows to change to snow tires. Principle of Snow Tires: The tread that comes into contact with the road surface uses a special silica-based compound to ensure the tire remains exceptionally soft even at extremely low temperatures, thus providing excellent grip on ice. The tread pattern typically employs a cross-Z-shaped siping technology, which not only enhances braking performance on snow and ice, shortens braking distances, but also delivers optimal traction. Description of Snow Tires: These tires are designed for use in snowy conditions. The rubber tires are equipped with metal studs to increase traction. In colder regions prone to snow accumulation, such as Russia, people use these tires during winter.

What is the break-in period for a motorcycle in kilometers?

The break-in period for a motorcycle is 500 kilometers. After each new motorcycle leaves the factory, due to the small clearance between engine components and rough moving surfaces, a break-in process is required to achieve optimal fit between gears, pistons and cylinders, shafts and bearings, etc. Precautions during the break-in period: During the break-in period, the maximum speed should be controlled. Generally, the driving speed should be kept below 60 km/h with variable speeds, avoiding prolonged driving at the same speed. It is advisable to drive at different speed ranges appropriately. Try to avoid carrying passengers or cargo during the break-in period: For motorcycles with gears, frequent gear shifting is recommended. After driving 1,000 kilometers, it is advisable to run at high speeds under safe conditions. Note that high-speed runs should be done before and after oil changes. During the break-in period, it is important to avoid aggressive throttle operation, sudden acceleration, and prolonged high-load driving. Applying some load appropriately can help components fit better. There is no need to be overly cautious, as this may not be beneficial for the motorcycle.

Why is the tractor emitting white smoke?

The reasons for a tractor emitting white smoke are as follows: White smoke emission: When the diesel engine has delayed fuel injection, low injection pressure, or poor atomization, it can lead to white smoke emission. During cold starts in winter, white smoke from the exhaust pipe is normal and will gradually disappear after running for a while. Poor atomization of the fuel injector: Poor atomization causes incomplete combustion of diesel, resulting in white smoke. Repairing the fuel injector can solve this issue. Low cylinder pressure: Some diesel fuel turns into oil vapor without being burned, leading to white smoke from the exhaust pipe. Damaged cylinder gasket: If the engine has been used for a long time, the cylinder gasket may be damaged or the cylinder itself may be worn out, allowing coolant to enter the cylinder. In this case, replace the cylinder gasket and tighten the cylinder head bolts strictly in order using a torque wrench. It could also be due to uneven contact between the cylinder head and the cylinder block after prolonged use, requiring the cylinder surface to be ground flat with specialized equipment.

Do I still need to display the vehicle inspection sticker in 2021?
