How to Set the Clock in a 2004 GMC
by Leonardo R. GrabkowskiAll 2004 GMC vehicles, including the Sierra, Sonoma, Safari, Envoy and Canyon, come with a digital clock. On all models, this clock is built into the GMC's radio. Because GMC trucks, vans and SUVs use similar audio equipment, the process of setting the clock in a 2004 GMC is similar between vehicles. Some Safari models may not have a "Set" button. For these models, revert to the "All Other" clock-setting instructions.
