I just found out about this as well. I have a 2012 Equinox with the 7″ touchscreen, but found out just the other day it’s in fact NOT MyLink when I tried to go to the dealer to have the software updated.
I purchased in Aug 2011, and at the time the salesman told me the car had MyLink. When I asked why the Pandora app was missing, he told me the radio was so new that a software update would be coming later that would add all of those features. I’ve been checking every 3 months or so thinking eventually the update would come out on the owner’s website, but nothing ever came. That’s when I started digging around and found this thread.
This is kind of ridiculous if you ask me. I’ve been corresponding with someone at GM customer service, and so far I haven’t gotten very far, even after showing him the article about the class action lawsuit. Makes me think GM will just brush this off as nothing while we all got basically screwed out of the MyLink system.
