Android car navigation cannot be set to play music when turned on.

The reason is that the vehicle navigation of the Android system is carried out through the combination of vehicle GPS (global positioning system) and electronic maps. It can conveniently and accurately tell drivers the shortest or fastest route to their destination, making it a good helper for drivers.

Geostationary satellites were originally used for military and aviation navigation. In the 1980s, the U.S. government relaxed restrictions on the use of geosynchronous satellites, opening up new horizons for the subsequent widespread use of geosynchronous satellites. Subsequent commercial communications satellites greatly improved the accuracy and coverage of communications satellites.

Extended information:

The vehicle navigation system mainly consists of two parts: the navigation host and the navigation display terminal. The built-in GPS antenna receives data from at least 3 of the 24 GPS satellites orbiting the earth to determine the car's current location.

The navigation host can determine the exact position of the car in the electronic map by matching the position coordinates determined by the GPS satellite signal with the electronic map data.

On this basis, functions such as driving navigation, route recommendation, information query, and AV/TV playback are realized. The driver only needs to watch the screen on the display, listen to the voice prompts, and control the above functions through the remote control in his hand, so that he can drive with ease.

The car GPS navigation system consists of two parts: one is the GPS receiver and display device installed on the car; the other is composed of the computer control center, and the two parts are connected through positioning satellites.
