Fair enough hyperboimmv, I see what you mean about false expectations. All I can say is it works in my car, and I have made a board which I will give to you guys to try. If you are happy with it, we can then see where it goes from there. At that point we can look at pricing, but I'm sure it will be reasonable. If I can secure enough business, perhaps I can contact a moto wholesale ditributor and get better pricing on the HF850 module. I'm thinking the whole solution should be around $200-$250 depending on what the moto goes for.

Let me clarify a few things though, about how and what it does.

It does NOT work in conjunction with the OnStar Navigation interface. It simply reads the button pushes from the mirror, and communicates that to the moto HF850 module. As far as I know, the mirror on all GM cars is the same, and acts only to supply keypresses to the onstar unit. It has no sophistication itself. My unit should work in a car with navigation, just nothing will display on your nav when a call is being made or received.

It WILL sense off hook status from the moto module and mute the radio via class 2 data command, exactly as the onstar unit would have done it if it were still installed. The audio from the moto module (which is actually received via bluetooth from your phone) is sent to the cars amplifier which is also switched via class 2 data to take the input from what was the onstar device, and is now my interface module. When the call is over, the radio will unmute, and the amplifier will be switched to take the radio's input.

I promise I will make a video showing all of this more clearly once I get back home next week. It will show how to install the unit and how to make and receive calls.

I will also provide pictures of my onstar equipment that was removed and connector information from my service manual that shows the units interface.

I'm hoping that they are the same as my 01 DTS. IF so, its a plugin.

Now if you already have the moto kit installed, you need to unplug all the connectors including power, mic, speaker, AND keypad. This all goes away. The only thing you keep is the core module as shown in my pic. The board I'm going to give you plugs right in where all those cables were. The onstar mirror buttons will replace your keypad, the onstar mic will replace your moto mic, the audio, power and class2 connections will go through the attached harness and plug right were the onstar unit plugged into.

As mentioned, I'll do all of this once I get back home. And I should be able to ship out ~5 units for trial so that they should be in your hands by next weekend. Once we confirm cable pinouts for your specific vehicles, I'll get your addresses.

Thanks again for all your inputs.
