While I'm waiting on my parts to work on a different issue, I thought I would try and tackle this one. I have a 2000 X5 with the business version am/fn cassette radio with 6 cd changer in the rear.

Here are the symptoms of this radio:

- The radio only allows me the ability to turn it on every once in a while. I've only been successful in turning 4 times since I've had the car.

- Unfortunately for me this time I turned it on, I can't turn it off.

- The radio has zero bass.

There is a very annoying loud (I mean LOUD!!!!!) buzz noise that comes from all speakers whenever the radio is in on.
* if the tape is on the buzz is there
* if the radio is on the buzz is there
* if the sound is turned all the way down, the buzz is ther
* if you turn the volumn up and down, the buzz volume stays the same.
* if the car is turned off and the radio is on, the buzz is still there.


No matter what the situation is, the buzz is there if the radio is on.

the buzz volumn is constant and nver changing.

I removed the 30 amp fuse from the fuse box in the rear on the right had side with no luck.

I unpluged the amp, the music stopped but the buzz continued.
