Navigation Radio Clock Set Procedure
WARNING: This page is about a different car, the 2012 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The navigation radio requires a GPS signal to sync the clock in the vehicle. To correctly set the clock after navigation radio replacement and programming is completed, perform the following to avoid future misdiagnosis:
- Move the vehicle outside with a clear view of the sky.
- Using the radio controls, select the navigation full map display screen.
- Verify that the "No GPS" Icon is not present on the top of the full map screen.
- After the GPS signal is confirmed, adjust the time on the radio Time Setting screen.
- Vehicle OFF, wait at least 5 minutes.
- Ignition ON, radio ON confirm that the time was saved.
