Bulletin No.: 10-08-46-001



Date: January 27, 2010



Subject: Radio Does Not Mute Enough When OnStar(R) Turn-by Turn Navigation Directions Are Announced (Increase Volume Setting or Request



Soft Mute Feature Change Through OnStar(R) Customer Service)



Models:



2009-2010 GM Passenger Cars and Trucks (Including Saturn)



2009-2010 HUMMER H2, H3



2009 Saab 9-7X



All Equipped with OnStar(R) (RPO UE1)



Condition



Some customers may comment that when the radio is on, it does not mute enough when the OnStar(R) Turn-by-Turn Navigation directions are



announced.



Cause



This condition may be caused by the customer improperly setting the radio volume high enough when the Turn-by-Turn Navigation messages are



played.



The 2009 and 2010 models with OnStar(R) initiates a "soft mute" feature when the radio is on during Turn-by-Turn Navigation direction



announcements. During the announcement, the radio can still be heard at a very low volume. Previous model years initiated a "hard mute" during



this function which completely muted the radio audio.



Correction



Instruct the customer to increase the radio volume while getting the Turn-by-Turn Navigation direction announcements. You can control the message



volume using the radio volume control, only when the Turn-by-Turn navigation messages are playing.



Some customers that were accustomed to previous model vehicles with the "hard mute" feature may be dissatisfied with the function of the "soft



mute" feature. For those customers, contact the OnStar(R) Customer Service Center by pushing the Blue OnStar(R) Button to speak to a trained



Advisor and request a change be made to the vehicle from the "soft mute" setting to that of the hard or complete muting of audio playback during



Turn by Turn directions. OnStar(R) will then create a case number. Advise the customer that the vehicle update should be completed Over the Air



within 5 business days, after which an OnStar(R) Customer Care advisor will follow-up with the customer to verify the fix. If the customer does not



hear back from OnStar(R) within a week, advise them to press the Blue OnStar(R) Button and ask for Customer Care to check status.
