The interface to the head unit is not the ordinary Pioneer cable, instead the CD changer attaches to the I-BUS (a CAN bus, Controller Area Network bus, J-2284, used as a local area network in the car) and uses it for communications to/from the head unit. The TWICE security computer will not allow the CD changer to communicate on the I-BUS unless it has been married to the car using the TECH 2 diagnostics tool.

The input used by the CD changer can be used if:
1. The MP3 player is connected to the I-BUS, and has been married to the car (i.e. has been accepted by the TWICE security computer).
2. The AS2/AS3 head unit must know that a CD changes is connected so the input is activated.
3. The MP3 player is able to talk to the AS2/AS3 head unit over the I-BUS.
I don't know of any hardware, except the original Saab CD changer, that is able to do this. How the communication with the CD changer is done is not available in public documentation that I know of.
It should be possible to reverse engineer the communication using available CAN bus software tools, but this is most likely not an easy job.
Ei ole nii lihtne. Kahju, et Audio Trollist asja ei saanud, tüüp tegeles asjaga ikka 3 aastat
