I have a 2012 Honda Odyssey, the Bluetooth volume all of sudden will not get loud I have the volume turned up on phone as well as Bluetooth in car. Restarted phone still no change.
Sorry for this probably silly question, but are you certain the phone audio is going through the car system? Is it possible that you're hearing it come from the phone itself? If so, then go to Settings>Bluetooth, tap the gear icon next to the car system, and make sure Phone Audio is turned on.
