Without Date Display

If your vehicle has an AM/FM base radio with a single CD player and preset buttons numbered one through six, the radio will have a clock button for setting the time. You can set the time by following these steps:

  1. Press the clock button until the hour numbers begin flashing on the display. Press the clock button a second time and the minutes begin flashing on the display.
  2. While either the hour or the minutes are flashing, turn the tune knob, located on the upper right side of the radio, clockwise or counterclockwise to increase or decrease the time. Instead of using the tune knob, you can also press the SEEK arrows, FWD (forward), or REV (reverse) buttons to adjust the time.
  3. Press the clock button again until the clock display stops flashing to set the currently displayed time; otherwise, the flashing stops after five seconds and the current time displayed is automatically set.

To change the time default setting from 12 hour to 24 hour, press the clock button and then the pushbutton located under the forward arrow label. Once the time 12H and 24H are displayed, press the pushbutton located under the desired option to select the default. Press the clock button again to apply the selected default, or let the screen time out.
