Don't Do This

Replace only the OnStar® microphone.

If normal diagnostic procedures lead to a failed OnStar® microphone, technicians are to replace only the microphone and not the entire rearview mirror assembly. Prior to the release of this bulletin it was necessary to replace the entire rearview mirror assembly if the OnStar® microphone had failed. Refer to the OnStar Microphone Replacement procedure in the Cellular Communication sub-section of SI (SI Document ID 1698672).
