So I've been on here reading threads about the audio/video stuff, but still have a question. With the PAC-GM32 and the GMOS-6 does it matter which one you use when replacing the head unit. I know someone mentioned that on the GMOS some of the wires are shorted together. But on the PAC it comes with the chime box externally to keep bells and sounds and the wires aren't shorted. Does this matter for the Non-Bose, Non-Onstar car? I also read that the radio randomly cuts off using the GMOS on Bose systems can this be confirmed for the Base model as well?
