Radio sound stops working


I have a problem with my BMW (330 Coupé 2001).
The sound of my radio stops, this is for the radio it self (FM) but also for the CD player and navigation.
The monitor it self keeps working while only the sound stops working, navigation still points me to the right direction.
Sometimes i can solve this problem by switching for example from FM to CD and back to FM.
The car has been to a garage for 3 times now, problem is solved for about 3 weeks and slowly coming back after it.

Right now the following modules has been replaced:

Radio module,
Monitor (in front of the car)

After replacing is goes fine for about 4 days to 3 weeks.
Then it drops once, switch from FM to CD and back, problem solved, this works for a few times, after about 6-7 times it just stops the sound.

I called a dutch BMW dealer, they told me it has to be the amplifier (replaced after they gave me the advice to).
They where able to tell us that its a well known problem with the BMW 3-serie with full options.

When it works the Harman Kardon sound system works fine, great sound actually.. but when it works.
I hope someone of you can help me out with this problem, I have it now for almost 2 years and no one is able to tell me the (possible) solution.

thanks in advance.
