How to Set a Clock on a 2003 GMC Sierra

by Jalisa Summerville

The 2003 GMC Sierra;'s audio system comes standard equipped with four speakers and an AM/FM radio. The Sierra also provides vehicle owners with access to the radio data system, also known as RDS, which allows transmission of valuable travel information, such as up-to-date traffic reports, through the truck's FM tuner. Sierra trucks may or may not come with this feature, which is linked to the vehicle's clock.

Setting the Clock for Radios without Radio Data Systems

Tap and hold the "HR" (hours) or "MIN" (minutes)arrow for at least two seconds.

Press the "HR" (down) arrow. Scroll until the correct hour appears on the clock display.

Tap and hold the "MIN" (up) button. Scroll until the correct minutes appear on the display. You can set the time whether the vehicle's ignition is on or off.

Confirm the time. Press and hold the "H" or "HR" and "MN" buttons at the same time for at least two seconds. If the time is not available for that particular FM radio station, the words "NO UPDAT" will show on the display.
