Hi. Can't seem to find the answer to this. Is there a way to adjust the volume of bluetooth calls (so the person calling me sounds louder in the cabin)?
adjust the volume with the volume controls on the steering wheel. Please note that as you increase the volume so you can hear better, it decreases the microphone sensitivity to reduce the possibility of feedback.
Any and all bluetooth-related audio (Pandora, Android Auto, or calls) depend on both the volume setting on the phone and the volume in the car. Turn up the volume on your phone.
What I've found is this. Not tested for Bluetooth phone calls but... When the GPS is giving voice status or directions and I use the volume control on the steering wheel it will change the GPS volume (not the audio music I was listening to). I have to do it during the actual voice prompt. Perhaps the same thing applies to Bluetooth phone calls.
It does, but again, that's only the car's volume. If you turn the volume in your phone too low, the car volume can't compensate.
If all does not work with car buttons, pressing volume button on connected phone will lower the bluetooth volume as well, and only bluetooth volume.
