2011 Impala OnStar Location/install tip
Posted: January 9th, 2012, 2:22 pm2011 Chevrolet Imapla, The location of the OnStar module is in the trunk driver side fender well, behind the trunk trim. The installation was very simple, just disconnect the two module connectors (one white and one black) on the OnStar module and plug into the Bluestar 2010. You can't mess up, they are of different sizes and will only fit into the correct socket. 10-15 mins to install
