The reason for your issue is that the stereo (a Blaupunkt, I presume) is not communicating with the car body computer.

The reason for this is either due to missing wiring to make this communication, or

the stereo is of the more modern Puntos (the revision B).
These have a different CANbus connection.

I have been trying to find a way to make a Blaupunkt CDMP3 unit from a 2004 Punto work in my 2002 Sporting.

I am trying to find some professional help in decoding the stereo to prevent it from communicating with the body computer................
