Why is there no sound when playing music via Bluetooth in Accord?

[StBriella]

Here are the specific reasons why there is no sound when playing music via Bluetooth in Accord: Volume is not turned on: The volume on the car navigation system or mobile phone is not turned on; go to the "Settings" and "Sound" on the phone, find the "Media" option, and turn up the "Media" volume. Incompatible pairing code: The music playback programming of some mobile phone models is incompatible with the pairing code of certain car models, so only phone calls can be made but music cannot be played; changing the Bluetooth playback frequency band can solve the issue. Media audio is not turned off: The media audio on the phone is not turned off, causing signal interference with the Bluetooth function; go to the Bluetooth settings interface on the phone, turn off the media audio and keep the phone audio.
