Where is Onstar module in 2002 Sierra Denali?
Posted: September 23rd, 2011, 1:31 amDoes anyone have a 2002 Sierra Denali? How does Bluestar work for you?
2002 might not be supported. It is most likely the older analog only module. (Actually two modules a VIU and a cellular module piggybacked together.)
If you have red and blue connectors, you will know it is older version.
