Why can't I play music when my Regal is connected to my phone via Bluetooth?

[HZoe]

Regal Bluetooth connection to the phone can't play music because the car audio is muted, or not switched to Bluetooth mode, or the volume of the car navigation device or phone is not turned on. First, turn on the car audio mute, enter the Bluetooth interface, click on music, and open the phone's music player at the same time. You can directly click on the song on the phone to play. When the car's Bluetooth function is connected to the phone's Bluetooth, you need to find the multimedia option on the car display, turn on Bluetooth music, so that the music can be played normally. Some phone's music playback programming is not compatible with the car phone system's docking code, so of course you can only make calls, not play music. The call volume of the phone and the media playback volume of the phone are set separately.
