Condition

Some customers may comment that when the radio is on, it does not mute enough whenthe OnStar® Turn-by-Turn Navigation directions are announced.

Cause

This condition may be caused by the customer improperly setting the radio volume highenough when the Turn-by-Turn Navigation messages are played.

OnStar® initiates a “soft mute” feature when the radio is on during Turn-by-Turn Navigationdirection announcements. During the announcement, the radio can still be heard ata very low volume. Previous model years initiated a “hard mute” during this functionwhich completely muted the radio audio.

Correction

Instruct the customer to increase the radio volume while getting the Turn-by-TurnNavigation direction announcements. You can control the message volume using the radiovolume control, only when the Turn-by-Turn navigation messages are playing.

Example:

The volume can be adjusted during the Turn by Turn directions and during any of thefollowing Voice commands - Cancel Route, Route Preview, Repeat, Get My Destination.

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 thosecustomers, 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 fromthe “soft mute” setting to that of the hard or complete muting of audio playback duringTurn by Turndirections. OnStar® will then create a case number. Advise the customer that the vehicleupdate 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 customerdoes not hear back from OnStar® within a week, advise them to press the Blue OnStar®Button and ask for Customer Care to check status.
