I just bought an Audi 1.9 tdi from 2004/5 and have quite large problems getting sound out of the speakers from navigation and bluetooth phone. Microfonen works ok, since the receiver can hear me on the other end, but I can not hear the caller or something. I have attached some pictures so it might make sense. For info I have reset navigation screwed up and Down voulume both navigation and radio but without success, it must be said that the sound works fine in both speakers with CD and radio, the info is the model with amplifier in the trunk. Hope there is a kind soul who has an idea what's wrong

My Iphone 6 Has connection with radio with a line called Audi UHV 7489 and is paired with the radio
