Clarion drb4475 set the clock

Page 51 of the manual, under General Setup Menu, is Clock.
Here is where you set time, AM/PM, or 12/24 hour clock,

You can check on ebay for the face plate, but they are hard to come by. I would suggest that you call Clarion to see if they sell faceplates for your unit.

This should do it for the 235.. you have two different mode #'s listed for some reason.

Setting the Clock
1) Press and hold the BND button, and then press the DISP button to display the clock display.
2) Press and hold the BND button, and then press the DISP button for 2 seconds or longer.
3) Press the SRCH Up button, then set the current minute.
4) Press the SRCH Down button, then set the current hour.
5) Press the BND button, then the clock is set.
Notes:
• If you select another operation mode while you are setting the clock, the clock setting operation will be canceled.
• If you remove the vehicle's battery for a check or repair, the clock will be reset, so you must set it again.

After spending an hour, here is how you do it. With the radio playing, press and hold the BAND button, until the word MANUAL displays in the bottom left. Then press and hold BAND, plus DISP (4). The radio will then go into Clock mode. You can change the hours by pressing the left scan, and the minutes by pressing the right scan. When finished, press the BAND button. To exit MANUAL mode, press and hold the BAND button.
