I hope you can help.
I have a 728i (E38), recently whilst driving I lose sound, even though the radio remains on, I can forward tracks, switch radio stations etc.
On a couple of occasions mid way through my journey the sound comes back. While Im driving if the sound goes I have tried parking turning the iginition on / off still no luck. I have also tried disconnecting the battery/reconnecting/reconnecting the CD changer- still the same.
I have found that generally in the mornings the sound works- for a few minutes.
One of my friends said it might be a short in the wiring- what do you guys reckon it is- if it is a short is there any way that I can diagnose it rather than paying BMW £200 to do it?
Thanks in advance,
