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.
