When I bought my A4 it had a Nokia 616 bluetooth car kit fitted by it's previous owner. The kit works really well with any bluetooth enabled phone but my issue is the volume. The kit is wired via the car stereo (Concert II+) but the default volume on calls is way too LOUD! The stereo volume control does not work during calls and with the Nokia volume at minimum it's still excessively LOUD. I suspect that it is a default setting on the input channel that needs to change.I'm assuming the kit is wired to an aux input on the stereo so my question is, is it possible to adjust the input volume using VAG-COM?
Any help would be greatly appreciated.
