How to Set the Clock in a 2007 Chevy Truckby Lisa Bass
At first, having the incorrect time displayed on your truck stereo unit is annoying. After a while, it becomes more than annoying, especially if you can't figure out how to set the correct time. Fortunately, many 2007 Chevy trucks came equipped with a radio data system (RDS), which enables you to tune to an FM frequency to set the digital clock on the stereo unit to the correct time. And if your truck doesn't have an RDS, setting the clock is simply a matter of pressing the right buttons.
Trucks With RDS
Look for a pair of buttons labeled "HR" (hour) and "MIN" (minute). They are usually located in the lower right corner of the stereo unit.
Press the two buttons at the same time until you see "RDS TIME" on the radio screen.
Hold the buttons down again for two seconds to accept the RDS time. If the time isn't available, you'll see a "NO UPDAT" message on the screen.
Wait for the correct time to appear. In some cases, it will take several minutes for the system to set the correct the time.
Trucks Without RDS
Press and hold the "HR" button on the lower right side of the radio panel until the hour digits show the correct hour.
Press and hold the "MIN" button next to the "HR" button until the minute digits show the correct minutes.
Turn your engine off. Press "RCL" and either "HR" or "MIN" to view the time without a key in the ignition.
