2011 Sierra Factory Bluetooth Firmware update


Recommended Posts

Posted

I just received a letter from GM stating that a bluetooth firmware update was available for my 2011 Sierra. It stated if OnStar was expired (mine is) to press the OnStar button twice and tell them I need the temporary OnStar account for the Bluetooth update. It also stated the firmware update would be done via OnStar and also I would get 30 days OnStar coverage at no charge.

 

Since the Bluetooth handsfree works great with my current phone, I will just wait until we have a trip planned to get the 30 days of OnStar free. The letter said the offer was good until 2016 I think.
