Mein Auto: 745Li
2002 745Li no sound from speakers

Bimmer Community,

I've recently started experiencing troubles with the stereo system in my 2002 745Li. At first every now and then there would be a loud static sound coming out of my speakers when I tried to play a cd or listen to the radio. Initially it would just go away in time or by turning the radio system on and off. Then it would go hours or a whole day without working. I could start the car the very next day and everything would be back to normal for a day...maybe two, maybe 3 days. The problem would eventually reoccur.
Fast forward 2 months and now the entertainment/nav system is working, there is no static anymore, but NO sound is coming out of the speakers at all. Whether you try to play a cd or the radio. Every now and then you hear the intended station or cd for about a 1 second then nothing.
Has anyone experienced the same problem or anything close??? If so, are there any fixes that I can try on my own???
I took the car to a shop today and they told me that my amp seems to be bad and that it would cost $1,250 for a new amp and $200 for them to install and program.....a total of $1,450 to hear music again.
PLEASE HELP!!!

In both cases above your problem is the ASK unit which is the main sound controller in the car.... it's the single CD Player in the dash.

VERY common problem ...most folk just replace it....look on Ebay for one....

Not in the Trunk ...the one in the 'dashboard'...next to the steering wheel ...

This is the Sound Controller for the door speakers.

Looks like this :

YES ...as all units in the car are connected together in a fibre optic loop.

If you bypass your ASK unit in the dash with a Fibre Optic MOST Bus Loop connector you'll find your Nav Unit will start working again (except you won't get any sound).

REPLACE YOUR ASK UNIT !

The ASK unit (single CD player located in the dash) is the Master Sound Controller in the car.....this is broken.

Because it's broken it's causing the NAV unit to also not work.
