In the navigation screen, blue represents the default route of the navigation system, red indicates traffic congestion on the current road section, yellow signifies slow-moving vehicles, green denotes smooth traffic flow, while gray usually comes with construction signs to indicate that the road section is currently under construction and should be avoided. Navigation precautions: Do not expose the device to sand or dust environments to prevent dust from entering the navigation system and causing instrument damage or malfunctions. Do not use chemical reagents or cleaning agents to clean the navigation device, as this may damage the machine's surface and corrode the paint. Avoid charging the GPS in excessively cold or hot locations, as this could impair battery performance. Do not expose the device to direct sunlight or place it in high-temperature environments to prevent overheating, which may lead to malfunctions or hazardous situations. If the navigation device malfunctions, do not attempt to disassemble it yourself; instead, send it to professional repair personnel for servicing. Do not use overloaded power sources, forcefully bend, or place heavy objects on the power cord to prevent overheating and potential fire hazards. Ensure all cables are securely and neatly connected to the navigation device to avoid damage caused by messy cable arrangements leading to falls.
