7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

1 of the units on your Fibre optic
Line is bad . This will cause the
Problem your having . You can
Buy a Fibre loop to find the bad
Unit by looping each unit out
1 at a time .

if it was your amp . You would still have sound
from front speakers , as those are controlled by
your Ask Unit ...

No audio

With the car turned off

Open glove box unplug fiber optic loop "lollipop" leave it unplugged for 6 to 10 minutes. The "lollipop" is located behind the little door in Glove box. Plug it back in then turn on car. Sometimes these units need to be reset. This happened to me a week ago.

Everything works as it should

I may have the same problem.
But I didn't see any little door in the glove box. Maybe I didn't know what to look for? 07 750li

Same problem

I had a xenon l/h/s bulb go out. I checked all fuses before replacement of bulb. Changed the bulb and now I too am having no audio, radio, cd, door chimes, or parking sensor.
I unplugged the lolipop as suggested and checked all fuses. 08 750LI
