    Smile Clock Adjustment Procedures

    Need some help trying figure out how to adjust my clock on the radio; got a 2004 Silverado 2500HD Duramax. Normally it's pretty intuitive, both I'm completely lost on this one, thanks in advance for the assistance!

    If your radio is the same as mine, there should be two small buttons on the bottom left. They are almost recessed, and are easy to overlook. Just push and hold the one on the left to change the hour and the one on the right for the minutes. Hope that helps!

    Default Thanks

    Matt, many thanks, yes, I found the 2 little buttons the other morning after I posted the question. The sun was shining perfectly and my old eyes could see clearly at that point. Have a great day and many thanks again!
