Paul,

Agreed....however...i understand that the cig plug steps down the voltage from 12 to 6....otherwise i think they would have offered the hardwire option...

i tried putting a ground loop isolater in the path..but it literally killed the signal

Crutchfield suggested that i wire the cig lighter plug into the wiring of the head unit...as you allude to...and i think that is the way it will have to go

i was just wondering if in fact anybody had actually done this...
