Just connect it to the internal 5V power supply, but this is only a USB power interface and cannot communicate. You also need to check whether the machine has this function internally. Install an FM transmitter plugged into the cigarette lighter port, otherwise you will have to replace the CD device with a USB interface. It is relatively easy to modify if you only use the USB port for charging, but it is very troublesome to use it to read songs from a USB flash drive and then play them. Modification is not recommended.

What are the consequences of driving without coolant?

Driving without coolant can leave the car's engine and radiator unprotected. A lack of coolant affects the heat dissipation efficiency of the radiator, preventing it from achieving the necessary cooling effect. Without proper coolant circulation, the engine may overheat, and in severe cases, this can lead to engine damage. In cold climates, it may also cause the engine or radiator to freeze, resulting in engine failure and rendering the vehicle unusable. Methods to check if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it likely indicates low coolant levels, though it could also be due to excessively high cylinder temperatures. Inspect the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add coolant promptly. Check the water level markings on the coolant overflow tank. The normal coolant level should be between the maximum and minimum marks. If the coolant is below the minimum mark, it indicates a deficiency.

What is a car speedometer?

Car speedometer is an application used to view the driving speed, supporting both miles per hour or kilometers per hour units. The speedometer function requires strong GPS signal support, and can display speeds up to 220 kilometers per hour. Many car dashboards now use electronic speedometers, with a common type obtaining signals from the speed sensor on the transmission, causing the pointer to deflect or display numbers through changes in pulse frequency. Here is more related information: Traditional speedometer: The traditional speedometer is a typical mechanical odometer connected to a flexible shaft containing a steel cable. The other end of the flexible shaft is connected to a gear on the transmission. The rotation of the gear drives the steel cable to rotate, which in turn drives a magnet inside the odometer housing to rotate. The housing is connected to the pointer and positions the pointer at zero through a hairspring. The speed of the magnet's rotation causes changes in the size of the magnetic field lines, disrupting the balance and thus moving the pointer. This type of speedometer is simple and practical, widely used in vehicles of all sizes. However, with the development of electronic technology.
