This is my first post, so forgive me if this has been asked and answered before. I searched this topic in this forum and found no good results.

I want to install the car kit, but I am not sure if it will work with OnStar. I want to take advantage of the muting and other integrated features. I called tech support for the car kit and was told that they didn't know if it would work or not - that it was hit or miss. Then I found THIS site. I bet somebody here has an answer.

Thanks!
