Call Eddie or Tom at Becker North America and ask if they have any suggestions short of you sending the head unit in to them for testing.
That's assuming you have the original Becker radio.
The only thing I can think of is to pop the pins out of the harness and reverse the front and back wires to see if the issue moves to the front. If that's the case you know it's the radio.
