Poor Radio Reception Cars affected: Evo 4 onwards, GSR models (or models fitted with rear window glass antenna) Symptom: Poor radio reception. Problem and cure: From the Evo 4 onwards the GSR models were fitted with a rear window glass antenna for the radio (the top 2 'lines' across the rear window glass, seperate from the window demister). This antenna has a booster amplifier which is required to get a good reception. The booster amplifier requires a 12 volt feed to work but often this has been disconnected. Remove the radio from the facia (you may find it easier to actually pop out the facia surround, remove the ash tray first) and find the radio antenna cable. The feed cable to the amplifier runs next to the antenna cable (see photo), check to make sure that this has a switched 12 volt supply (switched via the radio being turned on or via the accessory feed from the ignition).   Approximate cost of repair: N/A Back to question page
