How to set clock on '03 stock radio
 

I bought a used 2003 Blazer 2 door and have no owner's manual. I can't figure out how to set the stock GM radio. It is a am/fm with no tape or CD player. Very basic and I have yet to figure it out. What's the secret?

on a lot of gms theres usually a "set" button. you hit or hold that then the "seek" and "scan" buttons control your minutes and hours

I don't see the 'Set' button or the 'Hr and Mn' button on my radio.
