Hi, does anyone else notice that music sounds quieter and weaker in Bluetooth mode rather than wired? Wondering if I may be doing something wrong.
I'm ok with it for now because I have an iPhone 12 and can still connect using the lightning to USB connection.

Thanks

Actually, I may have just found a workaround. I could plug a USB to Bluetooth adapter in the USB port. Has anyone done this?

Is the volume maxed on your phone when it’s connected to the car?

Mine works perfectly.

Just in case, I went to Configurations > Advanced > Bluetooth Audio Codec > aptX or aptX HD, depending on your receiver.

With the same setup on my car I suffered a lot with the Google Pixel. OP5 is a breeze by comparison.

If connection is difficult, one thing that may help is to delete Bluetooth data:
Configurations > Apps > ... > Show System files > Bluetooth Share > Storage > Clear data

This will not remove any of your BT pairings.

Try to connect your phone in the USB port and see if there's any difference in sound level.
