Quiet Bluetooth Audio

Wondering if others have had this happen with their 3gen JBL systems. When I start my truck and it connects straight to Bluetooth audio, shortly after starting the audio will get very quiet, sometimes for 30 seconds, sometimes for a few minutes sometimes the audio never comes back to full volume.
I’ve tried switching sources and then going back to BT, still quiet. FM and Satellite will be loud.
I’ve tried forgetting the device and pairing it again, still happens.
Any thoughts on what’s going on?

 

I’m having the exact same issue too. The radio volume is normal but anything via Bluetooth has extremely low volume.

Has anyone found a solution for this?

 

No, never found a answer. The dealership flashed the system but that didn’t help. They couldn’t find anything wrong.

 

Okay thanks Adam! I’ll probably take it to a car stereo shop and ask.
