Well basically the only thing that I think would be useful for me is the class 2 communication. I have a motokit with the button module on my dash. I have no problems leaving that there, if I could make it go through the radio, with the radio being controlled by the class 2 interface, I would just have to wire my module through to the audio. So I guess what I am saying is if your board would have inputs I could tap into, to make the radio "accept a call and route audio through the speakers" I could probably do the rest. I am assuming that the radios are all the same for a certain year group (communication wise (read:class2)). I just don't know what models had the mirror driven onstar.

I mean as it stands right now, I am trying to figure out a way to 'safely' attach my motokit to my center and left channels, and power off the radio when the phone is active. But since I have no way of attaching to a mute wire, and would have to cut the 12v B+ wire to the radio, effectively removing all power, I don't see an easier way of doing this unless I have access to the communication bus. When I get home, I am going to look over some schematics for my model and a few newer blue onstar button based models. In theory all I would need is the Class2 TX and RX, and Audio - and + for at least one channel that is accessed by the radio via the class2 "switchover, or call mode".

And RustyBlazer, I think that there isn't a lot of interest because there have been a lot of products like this that have been thought up, and never actually produced. I think people don't put forth the effort to say they are interested only to have their hopes lost because the product never sees life. I am sure once like 5 people on the board have this, you will have a large thread.
