How do you replace aerial on VW Polo?

To replace the aerial on a VW Polo, first, ensure the vehicle is turned off and the radio is disconnected. Carefully remove the old aerial by unscrewing it from the base, which may require a special tool or a simple wrench, depending on the model. Once removed, install the new aerial by screwing it into the base securely, and reconnect the radio. Finally, test the reception to ensure the new aerial is functioning properly.
