Please discard Corporate Bulletin Number 10-08-46-001A.
This condition may be caused by the customer
improperly setting the radio volume high enough when
the Turn-by-Turn Navigation messages are played.
OnStar® 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.
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® Customer
Service Center by pushing the Blue OnStar® 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® 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® Customer Care
advisor will follow-up with the customer to verify the fix.
If the customer does not hear back from OnStar® within
a week, advise them to press the Blue OnStar® Button
and ask for Customer Care to check status.
