When the engine is running, the radio is turned on, and as soon as I turn the steering wheel left or right, I get a buzzing noise? I had a DAB radio fitted and it was still there, so I took that out again. What on earth could be causing this noise? Yes I can turn the radio off but that’s not the point. Please help.
It’s possible that whoever installed the radio ran it through the power steering assist fuse, or some newer vehicles even have electric steering, causing fluctuations in the power being sent to your stereo.
