Has anyone tried to register a new style2007 or 2008Sierra at mygmlink.com? When I last checked they only supported Sierra and Sierra HD through 2006 and Classic Sierra (old style)through 2007. Although, I think they list Silverado (Chevy) through 2008.

So far no response to e-mail form at gmc.com early last week. And the form to add vehicle support to mygmlink.com only lists 1980's and 1990's Sierra (I picked 1990's and in comments said "actually 2008 Sierra". I finally called GM Fridayand they saidI should try again in30-45 days.
