Setting the clock on a Pioneer car stereo is a simple process that can be done in a few minutes. First, remove the battery cover and unscrew the clock face. Next, remove the two screws at the back of the clock face. Finally, remove the back panel of the stereo and place it on top of the battery cover. Now screw in each screw until it’s tight. Place the clock face back on top of the stereo and screw in each screw until it’s tight.
