I have a 2001 Fiat Seicento SX. It came with a very classy Blaupunkt stereo (complete with casette player). However I dont actually own any tapes...So I decided to install my Kenwood CD player. Connected it all up with no problem, harness works as there is power to the stereo. This is where my issue happens. There is no sound when it is playing CDs, Radio or Aux in. Yet when I change from source to source it beeps at me to tell me its changed.

After doing some digging for similar issues I have come to a dead end, can anyone please shed some light before I end up losing the plot? :bang:
