GMOS-04 no sound
I tried a search but for some reason didn't come up with a solution. The set is, 09 Z06 no bose using a Pioneer X-930BT with the GMOS-04 harness. I have the realy connected and I also have the remote wire from the stereo connected to B3. The problem is I am not getting any audio to play, it chimes for the door chime through the speakers with it connected but it does not play any audio. What could I have possibly hooked up wrong? Any help would be greatly appreciated. Thanks.

you do not need the relay and do not need b3 connection
all connections are in harness only
you really should be using a PAC or CRUX harness with your 09 anyways as I only use the gmos04 on 2011,12 and 13 models
there is a blue white wire in the GMOS04 harnes which is where you need to connect the blue white from radio to.

I tried it without connecting to B3 and it wouldn't turn on, once I made that connection it would at least turn on but no audio. Other than the relay everything is all harness connected. Would having the relay cause the no sound? I had the GMOS-04 from my trailblazer SS and it said it was compatible so I figured I'd give it a try. I only did the relay because the instructions said 05+ corvettes needed it. I've never really liked the unit in the first place though. I'll look into those. Thanks.
