How do you replace the antenna of a 2007 Saturn?

To replace the antenna on a 2007 Saturn, first, carefully unscrew the old antenna from the mount on the roof of the vehicle. If it's stuck, you may need to use a wrench or pliers. Once removed, take the new antenna and screw it into the same mount, making sure it's securely tightened. Finally, test the radio to ensure the new antenna is functioning properly.
