GNUnilink is a PIC adaptor that emulates a Sony
Auto CD Multichanger, enabling the AUX input on
the rear of suitable Sony car radios. This in
turns allows the owner of such a radio to use
these inputs for a portable CD or MP3 player.
GNUnilink contains an optional serial link between
PIC and PC. Button presses can be sent to the
PC. The PC can set disk/track numbers/names and
provide a real-time counter.
