How do set clock 2007 Silverado 2WD

Setting the Clock (H-clock symbol, O-pwr symbol, f-music note symbol)
Without Date Display
AM/FM Base Radio with a Single CD Player
This type of radio has a
H
button for setting the time.
You can set the time by following these steps:
1. Turn the ignition key to ACC/ACCESSORY or
ON/RUN. Press the
O
knob, located in the
center of the radio, to turn the radio on.
2. Press the
H
button until the hour begins flashing
on the display. Press the button a second time and
the minute begins flashing on the display.
3. While either the hour or the minute numbers are
flashing, turn the
f
knob, located on the upper
right side of the radio, clockwise or counterclockwise
to increase or decrease the time.
4. Press the
H
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
H
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
H
button again to apply the selected default,
or let the screen time out

This worked on my 04 CTS. This is a CTS without the GPS.

1) Turn key to On or Accy
2) Wait for the radio/clock display to load up.
3) Push the Tune/Select button at the lower right of the radio display. Nothing will appear to change.
4) There is a button to the right of the radio diplay with two horizontal lines on it. Push the lower of the two horizontal lines. The clock set option should appear.
5) Turn the Tune/Select button until the time is correct.
6) Push the Tune/Select button to lock the time in.

Hope this helps.

1st remove the positive wire from the post. Next remove the negative wire. Next remove any retainers that are holding the battery in the mount. After you free the battery, remove it from the vehicle. Reverse order of removal to replace. reset clock, and radio settings. IF your radio has an anti-theft device and it becomes active due to the absebse of power (battery removal) you may need to contact your dealer for the code to release the device. Good luck, I hope I have helped.

With the radio turned off, you will need to hold down both the seek and scan buttons to active the clock setting.

Try this, put the key in the ignition and let it be on the first turn right marked "ACC" or you can turn off the stereo and you will notice that only the Digital Clock screen will show. Turn the Volume/Audio/Sel knob and press on the "DISP" button simultaneously for about 4 seconds then release the "DISP" button. The digital clock will start blinking, and then use the Tune/Seek arrows pointing up and down to change the time. If the hour digit is blinking change the hour and after you have changed it press "DISP" then the minute digit will start to blink change it using the arrows, when you are done press "DISP" again or leave the clock for between 4 to 8 seconds the clock will start working normally.

I hope this works for you.

Good luck!
