How do you change the aerial on your citroen c3 pluriel?

To change the aerial on a Citroën C3 Pluriel, first, remove the plastic cover around the base of the aerial by gently prying it off. Unscrew the aerial from its base, which may require a wrench or pliers depending on how tightly it is secured. Replace it with the new aerial by screwing it into the base and reattach the plastic cover. Ensure everything is snug and secure to prevent water leakage.
