My 95' BMW E38 recently broke down its audio system. I can't hear anything from radio or CD set. It is difficult to find the cause. I even tried connecting only amplifier and radio module (no luck). Things I have eliminated already:

  • Speakers are ok
  • Fuse in radio tuner located in the trunk is ok
  • Other fuses are ok too
  • Radio module is ok

My car has 4:3 TV and cassette slot in the front panel. Tuner, amplifier, CD changer, GPS, TV module and GPS module are located in the trunk.

Is this the factory radio setup that is installed in your car? – Gabriel Mongeon Aug 15 '13 at 13:40
Yes it is. I think it's the amplifier, but I'm not 100% sure. A used one costs around 100$ so I want to be sure i really need one. – Andrzej Bobak Aug 15 '13 at 19:18

It was the amplifier. All the other modules produced the correct signal. I exchanged the amplifier to a friend's device from E39, it worked.
