I just bought a 99 Grand Prix SE today. I didn't receive any manufacturer documentation with it and the clock on the radio is a few minutes off (plus we go through a time change in about 6 weeks, so I could use the practice). I realize this may be a stupid questions, but can someone tell me how to change the time on the OEM radio in this car? I know how to set the radio presents, but can't find what combination of buttons turns the clock into the set mode.
Thanks in advance.
