I just spoke to OnStar regarding the availability of the MyLink application for 2010 vehicles. This is what I was told: As of March 10, the application was made available to select 2010 vehicles, including the Acadia, Enclave, Traverse, Suburban, and a few others (apparently, these have Generation 9 hardware?). However, the 2010 Equinox and Terrain were not among them. The rep had no time frame for when or if it would be made available for the 2010 Equinox/Terrain. I was told to keep checking with them. Oh, well. . .
