Why is my bluetooth volume low?

[willy_manily]

Hi there,

I have the stock business CD radio with the factory bluetooth kit that is paired with my iPhone 6 Plus. I've turned up the volume up on the business CD using the volume knob during a call but I still struggle to hear the voice of my caller on the other end.

Any idea how to fix this? I've had a quick look through the settings on my phone and I can't see anything. i've also looked through the settings on my MID and I can't see anything to turn up bluetooth volume.

Moreover, is there a way to clear the recently called 'quick dials' on the MID. Half the numbers on there are wrong!

Has anybody else had any issues like this?
