rajamahal,
Exactly, I was getting the same three radios bit from the Chevy website service support at their 800 number. But on my build order for the 2012, which I have, there is no option for a special my link radio, only Nav or standard. Chevy may be backing into an extra, priced option because they were not ready to deliver on day one, but a lot of folks were told this was a standard for 2012 when we ordered.
Hopefully this is a software and not a radio problem– a problem of vaporware or software not delivered rather then some special chip in a new radio. If it is software , as I hope, then I will post when I gan get successfully registered on the myconnectedradio.com website and the mylink software updates uploaded– even the mylink site has the bugs of site newly delivered.
