    The SIR-GM1 connects to factory GM radios using the CD changer connector on the rear of the radio. I would say first see if this connector exists on your Pioneer radio. Should be 12 or 14 pins and square. I don't remember the amount of pins. If it has the socket as described you could order the SIR-GM1 from someone that accepts returns like Amazon and give it a try.
