• I have a wiring challenge - if I have a phone charger in the cigarette lighter socket then I have interference affecting the radio reception.

    What does this mean? I cannot listen to Radio 4 whilst driving - a frightful situation.

    Now, I suspect it's because the charger is a bit crap and is leaking into the ground circuit, which is shared by the radio.

    If I wired in a USB socket (taking switched power from the fuse box, in the drivers footwell) would this be sufficient separation to stop this interference?

  • Possibly. Ground issues aside, RF interference from USB chargers is possible if the circuit is badly designed or the manufacturing quality is poor - try another charger (12v to USB outlet) first.
