I know there have been discussions about this and I've read everything I could find including my owner's manual. Where the posted speed used to show up I only see 3 dashes now. I know that's all you will see if the speed is not in some highway database but I never see it anymore. As I scroll through the menu options that include speed, oil life, tire pressure etc. when I get to Timer it pops up two consecutive times as I move the menu wheel. I'm wondering if Timer should only appear once and the next one should be where I select posted speed. I may have to get to the dealer and ask or look at another Blazer with the same equipment.
