What are the reasons for no sound in the Bestune T77 audio system?
3 Answers
The reasons for no sound in the Bestune T77 audio system are: 1. The audio system volume is not turned on; 2. The music playback programming does not match the vehicle's docking code. The solution for no sound in the Bestune T77 audio system is to change the music playback frequency band or inflate the speaker system. Taking the 2020 Bestune T77 as an example, its body dimensions are: length 4525mm, width 1845mm, height 1615mm, with a wheelbase of 2700mm. The 2020 Bestune T77 is equipped with a 1.5L turbocharged engine, with a maximum horsepower of 169ps, maximum torque of 124nm, maximum power of 258kw, and is paired with a 6-speed automatic transmission.
I've encountered the issue of no sound from the Bestune T77 audio system, which usually has several common causes. If the audio suddenly goes silent, first check the basic settings, such as whether the volume knob was accidentally turned to zero or the mute button was activated. Sometimes it's a Bluetooth connection issue where the phone pairing failed, and the system automatically switched to mute mode. On the hardware side, the speaker unit might be damaged or the cables could be loose, especially after prolonged vehicle use, as vibrations can cause plugs to come loose. Software system failures can also lead to no sound, such as bugs after a head unit update, requiring a restart of the multimedia system. It's recommended to start with the simple fixes first; after confirming the settings are correct, then check the hardware. Last time, I found it was a blown fuse—the audio system's fuse is in a small box located under the steering wheel, and replacing it fixed the issue. Regular maintenance checks on audio connections can help avoid such troubles.
As a B70 T77 owner experiencing no sound from the audio system, I recommend troubleshooting step by step. First, check if the volume is turned up or mute is off. Then inspect external device connections like Bluetooth or AUX cables for proper insertion - if pairing fails, restart your phone or infotainment system. For hardware checks, open the door side panel to examine speakers for visible damage and ensure cable connections are secure. Sometimes system software updates cause glitches, so try rebooting the multimedia unit or performing a factory reset. If these don't work, potential issues could be a faulty amplifier or blown fuse (the fuse box is typically near the hood). Remember: avoid self-disassembly to prevent wiring damage. Regular system cache cleaning can also prevent sound failures. I've resolved similar issues through basic checks during my car maintenance experience.
