Hi all, I have a 2006 X5 with the standard intergrated blue tooth phone kit, what Ive noticed is that the volume during a call is really low...all the internal voice commands are fine but during a call is low i don't recall it being like this before.I have increased incall volume on phone and even swapped phone with no effect.Is there an adjustment for the car kit to increase volume.

Thanks in advance
