Hmmm

I assume you haven\'t added anything to the car recently?

If not, then I would guess (warning: armchair speculation) that it\'s an age-related wiring issue - either a ground rusting out, or a worn/frayed insulation allowing a short to occur...

As to how to trace it - I haven\'t got the foggiest - sorry

I would check if the the black earth wire has come away if it\'s an aftermarket headunit
