I finally got around to turning the radio on the other day and now it makes and awful buzzing noise when the truck is running. Doesn't matter if I play a cd or listen to the radio. It does NOT do it when the truck is turned off and the key in the acc. position.

My first thought was the new plug wires I bought did not have the RF shielding, but upon further investigation the box they came in states they are RF shielded.

What now?
