My GMLink Owners Center
 

https://www.mygmlink.com/main/US/en/gm/home

Has anyone used this site? My vehicle information wasn't in the database (bought it 10/21/05), but was able to enter it manually. I thought it might provide a little more info than OnStar. Found a section called 'Glove Box' that you can Maintenance schedule, create a service log, recall info. parts...
