Fan noise behind 730 N?
 
Turned the truck off this evening, and heard what sounded like a fan running behind the radio. Put my ear right up to it, and sure enough, a faint fan-like noise coming from behind the radio with everything off. Is there some kind of "cooling-fan" behind the radio??

Yep; it's a cooling fan (two, actually) built into the unit that exhausts into the dash that will stay on until it gets down around 120 degrees internally... :)

Very strange, past couple mornings, first thing in the morning, after the car's been sitting all night, before I even start it, I've put my ear up against the radio and can hear the same thing??
