Many Pioneer car stereo systems include the Pioneer Supertuner IIID tuner as an alternative to the standard AM/FM radio found in most Pioneer car stereos. Pioneer says the Supertuner IIID offers superior sound quality compared to that of their standard radio tuners. Many systems that include the Supertuner IIID tuner can play MP3 files, WMA files and CDs. A clock also is included in the in-dash display.

Press the "Function" button repeatedly until "Clock" is displayed.
Use the left and right arrow buttons to toggle between the hour and minute settings.
Use the up and down arrow buttons to adjust the setting selected.
Press the "Function" button once again to save the clock settings.
