All of a sudden the volume of incoming calls is impossibly low. Callers say they can hear me just fine. Any idea what the problem is and how to fix it?
I think there is a volume control that is only available when you are on the call. Check in bluetooth settings or maybe it is on the audio menu. Sorry for the vague answer, but details should be in the Nav manual.
Check the volume on your phone as well during your next in car call. If the in call volume on the phone has been turned down it will be less loud at the same car volume setting.
