Tested the 32 pin connector at the module and no good. 0.00 volts although there are two remote turn on wires coming out of the module. Both are bluish grey. First wire is giving volts second does not.

Jumped the remote turn on directly from the h/u to the 2nd bluish grey remote turn on coming out of the gmos-09 module. Finally get sound with out any chimes or OnStar prompt like ddalder stated. Although I hooked it directly to Pin A3 before and got nothing unless I had a bad connection on it on that attemp.

This sucks. We purchased this module at a custom audio shop 2 hours away because we were in the area and they happened to have it in stock.

good to hear its just a module and not somethin more sinister (in the bonnie) i had a feeling it was in the module, none of the Metra OS interfaces are worthy of even bein a paperweight, i refuse to sell them to people at work

When the cd player was actually working with sound, it was really quiet. Does anyone know why? I could have it on full blast and was barely putting out noise

possible the module, all you did was bypass the module for amp turn on, not for audio routing, correct?

Correct. Should I get a new module, or do you think that all of the GMOS-09 are bad?

Something to keep in mind is that the amp on/off for OnStar is controlled by the Vehicle Integration Unit (VIU). The reason the OnStar didn't work when you did the test above, is because you need to integrate with the VIU. The trick is in understanding the BIG PICTURE enough to have it all work together.

I don't see ANYBODY (except ddalder) in this thread that takes this into account.

Also, a word of CAUTION! There are too many cooks here . . .

EXACTLY! This is the question. The answer doesn't seem to be clear at this time. Darcy (ddalder) is asking the questions he is asking, in an effort to determine this very thing. I suspect he is still formulating the answer. He knows A LOT about what is in the car, but he has not yet had much experience with the GMOS-09.

I am the first to tell you I don't know the answer. But at least now you know the question. My recommendation is to work with ddalder (if he is still available) and provide him all the tests and info he may need. Darcy has been committed to solving this issue for a while now. I have the utmost confidence that he can (because of his superior familiarity with the idiosyncrasies of the Bonneville). It is also very important that everyone be PATIENT. This is an intricate problem and will take some planning and cleverness.

If there is something I can add, I will find an appropriate way. As of now, I do not want to be another cook . . .
