What does the GPS navigation system in the car mean? Is it a reversing radar?

GPS is a global positioning system. Simply put, this is a satellite system consisting of 24 satellites covering the whole world. This system can ensure that four satellites can be observed at any point on the earth at any time, thus ensuring that satellites can collect the latitude, longitude and height of observation points, thus realizing the functions of navigation, positioning and timing. This technology can be used to guide planes, ships, vehicles and individuals to reach their destinations safely and accurately along selected routes.

What is the parking aid?

It's called auxiliary parking outside the car, which means ranging radar. Now many car owners have installed them, and some cars have them in the original car, both before and after.

The system can synthesize the parking route predicted by the wheel tangent angle on the real-time image taken by the camera behind the car body. In addition to images, drivers can also be instructed by sound to deal with various situations when parking vertically and horizontally. However, the system has no auxiliary functions such as steering, acceleration and braking operation, and the driver must carry out these operations himself.

I hope it works for you!
