E90 base stereo no sound
Hi I have a 2006 330d with base stereo (no amp or tweeter) and idrive(ccc)
I just got my car back from the garage with no audio after getting the heater core replaced. They have refused to even look at the problem so I thought I’d have a look myself.
So far everything works as it should apart from the sound. I have checked all the fused and none are blown I have also checked the wires out of the navigation professional unit and the idrive screen and all seem fine.
Does anyone have any idea where to start or any issues that could cause this any comment would be appreciated
