There's a ghost in my machine! OEM radio spontaneously began receiving 12V power although ignition is NOT in the "on" or "accsy" position. Worked when keyed for the last 8 months or so then BOOooo, radio operates without being keyed through ignition. This is only the latest in a string of weird spontaneous occurrences. Guessing my recently deceased uncle is still driving His car when I'm away. This isn't normal...or is it? ?
