How do disconnect battery cable(s) at airport...

I have read that before about Edge (which I like) units causing battery drain.
Maybe just pull the fuse on the Edge rather than disconnecting batts?

I've had the edge on the truck since day 1 but since my new transmission has been in I only use it for the gauges. Is there a fuse in the edge unit or do you mean in the fuse panel? How do I know which fuse it is?...thanks...
