Does anyone know why when I plug a charger into my cigarette lighter socket I can not listen to am because of interference and how can I sort it cheers
I can only guess that the charger is lacking in any radio interference filtering . I presume it is very close to your radio ? Is it a cheapo jobby from the market ?
Replace the socket, they are only made of steel rather than copper or brass, there's probably corrosion on the base contact in the socket, this will cause interference.
