Made a copy of the software update Number 08-023-11 Rev A" (dated 8/12/11) and took it to my dealer. Unfortunately it only covers vehicles manufactured from December 10, 2010 to June 10, 2011. My vehicle was built in August 2011 so they could not update. MY ISSUE is that Voice recognition for Phone Book names does not work (only sometimes but very seldom). Dealer Service person had no suggestions. Can anyone make any suggestions?
