Condition



Some customers may comment on a buzz noise (from the land-line side only) during a call.



On any vehicle equipped with OnStar(R) (UE1) and Bluetooth(R) (UPF), an electromagnetic compatibility (EMC) buzz can be heard from the



land-line side only of the phone during a Bluetooth(R) phone call made with an older model global system for mobile communications (GSM)



phone. The buzz is only heard with older model GSM phones and is dependent on the distance of the phone from the microphone. The newer 3G



GSM phones or other cellular phones (CDMA, TDMA, etc.) have not shown this concern.



Correction



Equipped with Headliner Microphone (Cobalt, HHR (non-sunroof) H2, H3)



A new microphone and bezel has been developed to address this concern. Replace the existing microphone with GM P/N 20951265. Also replace



the bezel. Refer to the parts information table below for correct color/part number.



Equipped with Overhead Console Microphone
