Hi when my kajar was 6 months old the radio lost DAB & FM, I eventually got my local service department to change my aerial, apparently there was corrosion occurring. Now all is well

I also suspect corrosion somewhere in antenna circuits. Need to to go to official service, but as my family is using the car each day to avoid public transportation in COVID times, will have to postpone the visit to the service until better times or holidays.
