Bought an e92 the other day and I am getting a speaker thump when the car is woken up. It is HiFi (Option 676) if that helps any. Anybody have a clue how to fix this? The sound system also sounds terrible so don't know where to start looking to fix it.
The system has most probably been modified or attempt was made,
especially when you say it sounds terrible.
Btw, have you attempted to lower volume levels,
in addition to adjusting the various settings on the headunit?
The settings are all set to middle default.
I also can't hear the navigation.
