Why is there no sound when the navigation system is connected to Bluetooth?

Reasons for no sound when the navigation system is connected to Bluetooth: 1. The call volume on the phone is not turned on. 2. The volume on the car navigation system is not enabled. 3. The car Bluetooth device needs to establish a pairing relationship. Here is an introduction to car navigation systems: 1. Components: The car GPS navigation system consists of two parts. One part includes the GPS receiver and display device installed in the car; the other part consists of a computer control center. The two parts communicate via positioning satellites. 2. Working principle: In GPS observation, the distance from the satellite to the receiver can be obtained. Using the distance formula in three-dimensional coordinates and three satellites, three equations can be formed to solve the position of the observation point. Considering the error between the satellite clock and the receiver clock, there are actually four unknowns: X, Y, Z, and clock difference. Therefore, a fourth satellite needs to be introduced to form four equations for solving, thereby obtaining the longitude, latitude, and elevation of the observation point.
Last time when I was driving, the Bluetooth navigation had no sound, which was really frustrating. I quickly figured it out. The most common reasons include unstable Bluetooth connection—first, open the phone’s Bluetooth settings to ensure successful pairing and try again; the car’s volume might be too low or muted, so turn it up to the maximum and check for any sound; if the audio output is turned off in the navigation app settings, this could also happen—I need to open the app and check if the sound option is enabled; device compatibility issues are not uncommon, especially when an old car system doesn’t work well with a new phone—updating the app or system version might solve it; hardware failures like broken speakers are rare but shouldn’t be ignored—a simple restart of the car or phone often helps, and if it still doesn’t work, ask a car-savvy friend for help to avoid affecting travel safety.
